We've changed out the original Sensenich fixed pitch wooden supplied with the Jabiru 3300, for a Whirlwind GA-J2B 63" ground adjustable. However, it seems hard to get speed or economy. Anyone have some happy experience with the CH750/3300 to share ?
Hi Fellow Zenith flyers and builders, I'm in the process of fitting a new propeller to my CH701. I'm running a Rotax 914 turbo (115hp). I'm not keen on a constant speed propeller, so what propeller would be appropriate to get good results for my aircraft? If you have any experiences good, bad or otherwise, please let me know. Volkys
Between our local chapter meeting (Chapter 182 - Memphis) this morning and a DU banquet this evening, I didn't have much time to play in the garage today. Busy schedule during the week prevented me from getting any angle iron for a bending brake. So this afternoon I cut out the form for the second wing spar. I traced it out using the 1st spar so the hard work was the cutting with the Olfa knife. Fortunately, it cut cleanly. Winter weather moving in again tomorrow so play time might be…Continue

Completed the right tip. I've decided not to install lights, as far as I know they're not required for RAAus rego and I don't plan to fly at dusk. In any case, I can always make an access point in the tip later if required.
Really don't know why they didn't make the entire tip out of plastic, it would have been much easier to install than a separate nose tip!…Continue
Cut out the spar web doubler today. Used a dremel saw and smaller dremel tool to do the cuts on the .063 thickness aluminum. Went through a number of cutting wheels!! Also measured and cut out the upper and lower spar caps. Now I need to find a bending brake to take care of the 90 degree bends for the spar tips and doubler. Maybe I can build one.
Root nose rib 75-w-4-1 drawn out does not match to root rear rib 75-w-4-2
if I where to make the nose rib x=0 and y=90 instead of 80, and do the same to the rear root rib, it would look more like the drawing of the nose and rear rib together, on pg 75-wa-1
Last week I disassembled the wing, deburred everything and primed the joint surfaces.
I decided to rivet the rear structure - rear spars to rear ribs, rear strut bracket etc - but not to rivet the ribs to the main spar at this stage, in case any shims were needed to pack out the nose ribs.
Riveted the lower trailing edges and lower rear skin to the framework, turned the wing over (carefully!) and clecoed the nose ribs back on.
This week I clecoed the nose skin…Continue
Another decent weekend and I was able to get out in the garage. Got the lightning holes drilled for the spar. Also got the spar tip and the spar root doubler cut. Finally, I was able to draw the pattern for the spar web doubler. I expect I will have to machine cut it. I bought some cutting wheels for my dremel tool. Will see if I can do a rough cut with it and then file it down to specifications.

Has anyone attached a GoPro camera to the wing of a 601 XL? I am looking at ways of doing this - I hear the 3m adhesive mount will be strong enough but it would probably take off the paint when trying to remove it at a later date. Any advice?

Last week I had the the privilege of visiting a working U.S. Navy carrier out at sea as part of an EAA group. Fifteen of us were given a first-hand look at life aboard an aircraft carrier and Navy life at sea. This was truly a unique and unforgettable experience.…Continue

After realizing that I cut the original wing spar form from the wrong thickness metal, I was able to take advantage of a warm Saturday to cut a new form with the correct stock. I was able to use the original stock as a guide as I cut the form with an Olfa knife. It wasn't easy but I got a straight and clean cut. The form in the photos look ragged but I left the protective coating on.
If anybody could help I would appreciate it.
My 750 is nearly complete at as a kit. When I built the wings I ran the supply fuel lines at the lower fitting and the vent line to the fuel tank on the opposite side on top of the tank. At the time I didn’t consider what type of engine I was going to install. Now that I have decided to install a fuel injected engine, I realize that I need use the vent lines I ran for the return of the fuel to the tanks. But because there are only two…Continue
Yesterday I finished the last of the wing ribs. All nose, rear, root and flaperon ribs are done and I have cut material to form flaperon spars, rear wing channels and cut material for the wing spars.
Question, I wanted to post this as a status as many do but I don't know how. Can anyone teach an old dog a new trick --thanks.
Thinking about visiting "down-under" this Summer or Fall (your seasons) and wondering when and where the most popular home-built aircraft fly-ins might be. It would be great meeting fellow builders/flyers.
