<p>Any Cruzer builders having issues with outdated drawings? It was redesigned a couple of years ago to make it conform to much of the Super Duty model but the drawings I paid for are woefully outdated. I have to jump between the STOL, SD and Cruzer drawings to try to figure out the building sequence. All three models have some commonality, but you have to figure out for yourself what applies and what doesn't. Additionally, my pick list was also outdated and I make almost weekly calls to Mexico…</p>

It was redesigned a couple of years ago to make it conform to much of the Super Duty model but the drawings I paid for are woefully outdated.

All three models have some commonality, but you have to figure out for yourself what applies and what doesn't. Additionally, my pick list was also outdated and I make almost weekly calls to Mexico to get a lot of the small hardware which was not shipped with my kit. Midland messed up the construction of my wing spars and made the gear/strut fittings wrong. I spent a half hour venting to Nick in Ontario about my frustrations. I hope it helps.</p>ruddere cables cross under consoletag:zenith.aero,2024-03-05:2606393:BlogPost:9263722024-03-05T23:22:09.000ZLouie Lacyhttps://zenith.aero/profile/LouieLacy

<p>Hello everyone,</p>
<p></p>
<p>I recently purchased a partially completed CH701 kit from a local EAA chapter that had inherited it from a member that had passed away. The fuselage, empanage, and wings are mostly finished. Anyway I was looking at the wings and the notes the previous builder had made and he made the wingspan roughly five feet longer than the plans called for. So the final wingspan is 32 feet instead of the 27 feet. this also includes an extra two connectors for the flapperons…</p>
<p>Hello everyone,</p>
<p></p>
<p>I recently purchased a partially completed CH701 kit from a local EAA chapter that had inherited it from a member that had passed away. The fuselage, empanage, and wings are mostly finished. Anyway I was looking at the wings and the notes the previous builder had made and he made the wingspan roughly five feet longer than the plans called for. So the final wingspan is 32 feet instead of the 27 feet. this also includes an extra two connectors for the flapperons on each wing so there are six flapperon connectors on each wing instead of the four. </p>
<p></p>
<p>I wanted to reach out and ask if anyone had experience with extra long wings for the 701 and what kind of performance changes or build changes i should expect as I complete this project. <br/></p>
<p>Anyway thanks in advance, I am sure I will have way more questions as this projects gets rolling. </p>

<p>The hanger side of my hanger home (~4 years in the building- a one man job) is done except for the epoxy on the floor. The residence side should be ready this spring. The strip (1SC1, 1200 feet of grass) will be fully ready this spring as well. Looking forward to getting up in the morning, pushing that hanger door button and going flying. Hope to see some of you at SunNFun this spring. …</p>

<p>Zenith Aircraft Company is returning to Texas with its popular <a href="https://zenithair.net/builder-workshops/" target="_blank" rel="noopener">hands-on workshop</a>, to Boerne (pronounced "Bernie"), just north of San Antonio. The workshop will be held <a href="https://www.zenithair.co/zenithstore/product/february-workshop/" target="_blank" rel="noopener">February 23 & 24, 2024</a>.<br/> <a href="https://zenithair.net/builder-workshops/" target="_blank" rel="noopener"><img src="https://storage.ning.com/topology/rest/1.0/file/get/7991066878?profile=RESIZE_710x" width="175" class="align-left"/></a>The workshop will begin on Friday morning, February 23rd, inside a spacious private hangar at <span>Boerne Stage Airfield (5C1).</span></p>
<p>Zenith Aircraft’s hands-on workshops are primarily for first-time kit airplane builders and have become popular with sport aviation enthusiasts who are considering to build their own aircraft and are unsure if they have the required skills, workspace and tools. During the workshop each participant builds and assembles their own Zenith aircraft rudder tail section from a standard Zenith kit. The two-day workshop concludes once participants have successfully completed assembly of their own rudder tail section of the aircraft.<br/> In the process of building the rudder assembly, participants tackle many activities including learning how to read drawings (blueprints) and work with assembly instructions (manuals) under the expert guidance of factory staff. They learn the procedures for putting together an aircraft assembly, including drilling and blind riveting. In the end, they have an assembled rudder that is ready to install on a Zenith kit airplane.</p>

Most importantly, they learn that kit building is enjoyable and something that can engage the whole family. Many of our prospective builders bring their spouses or other family member, who often encourage them to move forward with the rest of the kit. With modern technology, such as final hole size CNC match drilled parts, and good instructions, aircraft construction has become much easier than most people think.”</p>

<p>The hands-on workshop is an excellent way to learn about building your own (amateur-built) kit airplane and about the many advantages of owning and flying an airplane that you’ve built yourself. Kit aircraft is a segment of general aviation that is growing (while much of general aviation activities continue to decline year over year). For many, building an aircraft is a very rewarding experience, and today’s modern kits make it easier and quicker to build than even before.<br/> Standard workshop fees are $375.00 (or $425 for the CH 750 Super Duty model) and include the complete rudder kit for a Zenith aircraft. Additional helpers are encouraged to attend and can participate for free. To learn more about the workshop program, <a href="http://www.zenithair.net/builder-workshops/" target="_blank" rel="noopener">visit zenithair.com</a> or call Zenith Aircraft directly: (573) 581-9000 (Mon – Fri, 8 – 5 Central). Space is limited, and prior registration is required for the rudder workshop. <a href="https://www.zenithair.co/zenithstore/product/february-workshop/" target="_blank" rel="noopener">Click here to register</a> for the February workshop in Texas.

<p style="text-align: left;">Zenith Aircraft Company is returning to Florida in early December to host its popular hands-on kit aircraft building workshop class. The workshop will be held <strong><a href="https://www.zenithair.co/zenithstore/product/december-workshop-florida/" target="_blank" rel="noopener">December 1 & 2, 2023</a></strong>, on the <strong>Sun ’n Fun Expo campus</strong> (home of the annual <a href="https://flysnf.org/" target="_blank" rel="noopener">Sun 'n Fun Aerospace Expo</a> each year in April).</p>
<p style="text-align: left;"><strong><em><a href="https://www.zenithair.co/zenithstore/product/december-workshop-florida/" target="_blank" rel="noopener">Registration for the workshop class in now open</a>. Space is limited so register early to secure your space.</em></strong></p>

<p>The Florida workshop will start on Friday morning, December 1st. The hands-on workshop class is aimed primarily at the first-time Zenith kit airplane builder, and has become popular with sport aviation enthusiasts who are considering to build their own aircraft and are unsure if they have the required skills, workspace and tools. During the workshop each participant builds and assembles their own Zenith aircraft rudder tail section from a standard Zenith kit, typically completed at the end of the first day.</p>
<p>The Sun ‘n Fun Expo campus in central Florida (conveniently located between Tampa and Orlando) is the “perfect time and place” to bring the Zenith workshops back to Florida this year, according to Sebastien Heintz, Zenith Aircraft’s president.</p>
<p><a href="https://zenithair.net/builder-workshops/" target="_blank" rel="noopener"><img src="https://storage.ning.com/topology/rest/1.0/file/get/10838742079?profile=RESIZE_710x" width="710" class="align-full"/></a>In the process of building the rudder assembly, participants tackle many activities including learning how to read drawings (blueprints) and work with assembly instructions (manuals) under the expert guidance of experienced staff. They learn the procedures for putting together an aircraft assembly, including drilling and riveting. In the end, they have an assembled rudder that is ready to install on a Zenith kit airplane.</p>
<p><a href="https://www.zenithair.co/zenithstore/product/december-workshop-florida/" target="_blank" rel="noopener"><img src="https://storage.ning.com/topology/rest/1.0/file/get/12245190652?profile=RESIZE_710x" width="710" class="align-full"/></a>“The rest of the kit is constructed the same way as the rudder, using the same tools,” said Sebastien Heintz, president of Zenith Aircraft Company. “People get far more out of the workshop than just a finished aircraft rudder: they go home with the knowledge, skills and confidence they need to build their own airplane. Most importantly, they learn that kit building is enjoyable and something that can engage the whole family. Many of our prospective builders bring their spouses or other family member. With modern technology and good instructions, aircraft construction has become much easier than most people think, and our workshop classes are good examples of this: most participants now complete the rudder kits during the first day.”</p>

<p>The hands-on workshop is an excellent way to learn about building your own amateur-built kit aircraft and about the many advantages of owning and flying an airplane that you’ve built yourself. For many, building an aircraft (from a kit) is a very rewarding experience, and today’s modern kits make it easier and quicker to build than even before.<br/> Standard workshop fees are just $375.00 (or $425 for the CH 750 Super Duty model) and include the complete rudder kit for a Zenith aircraft. Additional helpers, such as spouses or other family member, are encouraged to attend and can participate for free. To learn more about the workshop program, visit <a href="https://zenithair.net/builder-workshops/" target="_blank" rel="noopener">zenithair.com</a> or call Zenith Aircraft directly: (573) 581-9000 (Mon – Fri, 8 – 5 Central).

<p>I made a post on this topic somewhere in the blogosphere earlier and now I can't find it. So, I will try again here. I am looking at purchasing a circa 1997 "hangar find" Zenith 601 Kit (does not include an engine or the finishing kit). A local EAA technical counselor who has assisted with two Zenith 601 projects advised me about a wing spar AD. The wings are complete and in a cradle. Looking around at all the places I can think of I cannot locate any information on the wing spar AD. I also sent an email to Zenith yesterday and have not heard back from them. </p>
<p>The current owner of the old kit is looking for the builder’s log if any. Anyone have any further information they can share per the wing spar AD and what it would look like? I don't really want to disassemble completed wings to satisfy an AD but, obviously for safety, I will if I have to.

<p>I’ve got a little over 350 hrs on my 801 with IO-375 now.<span class="Apple-converted-space"> </span> I really like the engine - lots of power….. and heat. Piston oil squirters shift some of that heat into the oil, and it can be a trick to manage.<span class="Apple-converted-space"> </span> I found myself needing<span class="Apple-converted-space"> </span> to make a couple of adjustments along the way to get control of oil and cylinder head temps. It has been a fairly long journey to get it where I want it. Now that I am there, I figured it was time for a write up.<span class="Apple-converted-space"> </span> This is how one guy did it…..<span class="Apple-converted-space"> </span> I’m sure there are also other ways.</p>
<p></p>
<p>I solved the oil temp problem first, so let's start there...</p>
<p></p>
<p><a href="https://storage.ning.com/topology/rest/1.0/file/get/12219279282?profile=original" target="_blank" rel="noopener"><img src="https://storage.ning.com/topology/rest/1.0/file/get/12219279282?profile=original" width="200" class="align-left" id="img165026" name="img165026"/></a></p>
<p><span class="Apple-converted-space"> </span> I recognized when building that the oil cooler provided with the FWF would not transfer enough heat.<span class="Apple-converted-space"> </span> So I started with an AirFlowSystems 2006X, which has 13 rows and dissipates heat better than other coolers of its same size.<span class="Apple-converted-space"> </span> It looked like a good match for the IO-375.<span class="Apple-converted-space"> <a href="https://storage.ning.com/topology/rest/1.0/file/get/12219271485?profile=original" target="_blank" rel="noopener"><img src="https://storage.ning.com/topology/rest/1.0/file/get/12219271485?profile=RESIZE_710x" width="200" class="align-right"/></a></span> I mounted this on the firewall, and pushed air through it with a 4 inch SCAT tube connected to the front of the intake.<span class="Apple-converted-space"> </span> In theory this should have worked great, but it did not.<span class="Apple-converted-space"> </span> I hit oil temps around 225 in early climb, and had to adjust my flying to keep the temps from climbing higher.<span class="Apple-converted-space"> </span> I measured the pressure differential across it, and found it to be about 10 in Wg, which should be enough.<span class="Apple-converted-space"> </span> So despite a good cooler, and good pressure differential I was not getting enough cooling. I verified Vernatherm function (boiling water test), Engine timing, and confirmed that oil was flowing through the cooler without obstruction.</p>
<p></p>
<p><span class="Apple-converted-space"> </span>I got the idea that the angle of attack was causing decreased airflow through my intake - with less mass flow across the oil<span class="Apple-converted-space"> </span> cooler.<span class="Apple-converted-space"> </span></p>
<p><span class="Apple-converted-space"><a href="https://storage.ning.com/topology/rest/1.0/file/get/12219271881?profile=original" target="_blank" rel="noopener"><img src="https://storage.ning.com/topology/rest/1.0/file/get/12219271881?profile=RESIZE_710x" width="200" class="align-left"/></a></span></p>
<p><span class="Apple-converted-space"> </span>I moved the oil cooler to a new position <a href="https://storage.ning.com/topology/rest/1.0/file/get/12219272257?profile=original" target="_blank" rel="noopener"><img src="https://storage.ning.com/topology/rest/1.0/file/get/12219272257?profile=RESIZE_710x" width="200" class="align-right"/></a>directly ducted off the lower cowl where it would get more air flow with increasing angles of attack.<span class="Apple-converted-space"> </span> The air pressure differential across the oil cooler did improve, but the hot oil temps remained.</p>
<p></p>
<p><span class="Apple-converted-space"> </span>Next I measured my inlet and outlet areas (inlet 510 cm2) and outlet areas (412 cm2 - lower than most 801s due to the float mount bar).<span class="Apple-converted-space"> </span> Despite researching the optimal inlet/outlet ratio, I was not able to determine what the ideal numbers were for our STOL craft.<span class="Apple-converted-space"> </span> So I decided to add cowl flaps to experiment with a larger outflow area.<span class="Apple-converted-space"> </span> The cowl flaps about doubled the exit area when fully open.</p>
<p><span class="Apple-converted-space"> </span></p>
<p><a href="https://storage.ning.com/topology/rest/1.0/file/get/12219279065?profile=original" target="_blank" rel="noopener"><img src="https://storage.ning.com/topology/rest/1.0/file/get/12219279065?profile=original" width="210" class="align-left" id="img378851" name="img378851"/></a>They are adjustable, so I can set them <a href="https://storage.ning.com/topology/rest/1.0/file/get/12219279470?profile=original" target="_blank" rel="noopener"><img src="https://storage.ning.com/topology/rest/1.0/file/get/12219279470?profile=original" width="200" class="align-right" id="img610248" name="img610248"/></a>where they work best. This did the trick. Oil temps came down nicely and now only get up to about 210 with prolonged climbs in hot weather. They stay a pleasant 180-195 in cruise. Oil temp issues solved.</p>
<p></p>
<p>So now on to CHTs. <span class="Apple-converted-space"> </span></p>
<p></p>
<p>Unfortunately adding additional exit area to the cowl did not correct CHTs.<span class="Apple-converted-space"> </span> They were also climb limiting, with #4 reaching 425 pretty quickly in hot weather. I made several attempts to tighten up the baffling using RTV saturated fiberglass cloth.<span class="Apple-converted-space"> </span> In the end I thought I had it pretty tight.<span class="Apple-converted-space"> </span> It passed the light test easily.<span class="Apple-converted-space"> </span> But the CHTs remained high.<span class="Apple-converted-space"> </span> After several test flights I came to the conclusion that my baffling was as tight as I could make it, and was still not adequate. <span class="Apple-converted-space"> </span></p>
<p></p>
<p>I decided to make a plenum.<span class="Apple-converted-space"> </span></p>
<p></p>
<p><a href="https://storage.ning.com/topology/rest/1.0/file/get/12219272683?profile=original" target="_blank" rel="noopener"><img src="https://storage.ning.com/topology/rest/1.0/file/get/12219272683?profile=RESIZE_710x" width="200" class="align-left"/></a>The plenum started with a 3D scan <a href="https://storage.ning.com/topology/rest/1.0/file/get/12219273055?profile=original" target="_blank" rel="noopener"><img/></a>of the engine and cowl.<span class="Apple-converted-space"> </span> I imported these into CAD, and then created a plenum shape mold plug that sat just below the cowl, and mated up to the cylinder heads. I split the plug design into three pieces so that the layup would have adequate draft to be removed from the mold.<span class="Apple-converted-space"> </span> I cut the mold plug out of polyurethane tooling board (RenShape) on a CNC router (AvidCNC).<span class="Apple-converted-space"> </span> The size of the plug meant I had to make it in several pieces, which were then bonded together. The mold plugs were bonded to MDF<span class="Apple-converted-space"> </span> to create flanges.<span class="Apple-converted-space"> The plugs came out great. </span>I sealed the mold plugs and MDF and added some wax fillets, then I laid up the molds. <span class="Apple-converted-space"> </span></p>
<p></p>
<p><a href="https://storage.ning.com/topology/rest/1.0/file/get/12219273697?profile=original" target="_blank" rel="noopener"><img src="https://storage.ning.com/topology/rest/1.0/file/get/12219273697?profile=RESIZE_710x" width="200" class="align-left"/></a>The molds came out functional, but not as great as I would have liked them.<span class="Apple-converted-space"> </span> I was rushing the process a little in order to get the plenum on before Oshkosh.<span class="Apple-converted-space"> </span> I had to do quite a bit of resurfacing<span class="Apple-converted-space"> </span> on the finished molds, but I stall have the plugs and can make new perfect molds if I ever want to. <span class="Apple-converted-space"> </span></p>
<p></p>
<p><a href="https://storage.ning.com/topology/rest/1.0/file/get/12219273872?profile=original" target="_blank" rel="noopener"><img/></a></p>
<p>I decided to lay up the plenum in carbon fiber, with high temp epoxy (450F tolerant).<span class="Apple-converted-space"> </span> I would have preferred vacuum infusion for the process, but I was not able to get the high temp epoxy in an infusion viscosity.<span class="Apple-converted-space"> </span> So I laid <a href="https://storage.ning.com/topology/rest/1.0/file/get/12219274497?profile=original" target="_blank" rel="noopener"><img src="https://storage.ning.com/topology/rest/1.0/file/get/12219275484?profile=RESIZE_710x" width="200" class="align-left"/></a>it up using a traditional wet layup technique with vacuum bagging, and then let it cure overnight.<span class="Apple-converted-space"> </span> I also placed saturated carbon fiber into sealed bags, and then packed them up agains the lower cylinders to form the lower cylinder baffling.</p>
<p></p>
<p>I spent the next day temperature ramping the plenum parts in the oven - which is about a 12 hour process to achieve the strength and heat tolerance that this epoxy was chosen for.<span class="Apple-converted-space"> </span></p>

<p>I trimmed them up to fit as well as I could and then mated the lower pieces to the uppers.<span class="Apple-converted-space"> </span> This mating was done mechanically with #8 screws and nuts.<span class="Apple-converted-space"> </span> Sealing up the joins was accomplished with RTV.</p>

But since I now had access to the pressure area above the cylinders (much better than with a cowl), I decided to test it with a leaf blower.<span class="Apple-converted-space"> </span> I had an assistant blow the air stream into the plenum intake, while I felt around for air leaks.<span class="Apple-converted-space"> </span> I found several, and sealed them up. I suspect that if I had been able to do the leaf blower test on the original cowl </p>

<p>baffling it would have revealed large leaks.</p>
<p></p>
<p>Once the RTV was set, I made the first test flight with the plenum in place, and to my great satisfaction CHTs were outstanding.<span class="Apple-converted-space"> </span></p>
<p></p>
<p>I no longer need to step climb, or limit HP output for Oil temp or CHTs.<span class="Apple-converted-space"> </span> I am able to climb continuously, and if It is a hot day my hottest CHT might reach 410 (which I can live with).<span class="Apple-converted-space"> </span> All of my CHTs are under 400 in cruise, and usually 370-390.</p>
<p></p>
<p>I have to say that this was a long journey.<span class="Apple-converted-space"> </span> I did get some help along the way, and the most helpful and knowledgeable person that I encountered was Bill Genevro (of AirflowSystems) - who’s help was invaluable.<span class="Apple-converted-space"> </span> He was generous with his time, and provided very useful advice. I am glad to have finally reached a successful conclusion to my cooling troubles.<span class="Apple-converted-space"> </span></p>
