Throttle Reversing Bell Crank

Some time back, I replaced the Bing carb on my STOL 750/Jabiru 3300 with a Sonex/AeroConversion "AeroInjector" throttle body carb.  The AeroInjector's throttle body slide operates in reverse to most other carburetors in that the throttle cable pushes in to close the slide and reduce the rpm's to idle and the cable pulls the slide open for full throttle.  Typically, most builders use an AeroConversion throttle quadrant to reverse the cable direction.  By attaching the throttle cable below the…

Center Wing Adventures Day 166, 391 hours

I have been lax at keeping up with my blog entries but I haven't been idle. I have been dealing with a number of issues created by the factory and by me.

I backtracked a lot of rivet work when I discovered the factory installed L angle on the spar at the gear box stations blocked me from back riveting the flanges of the channels to the spar. This also required ordering AN3 bolts to replace the solid rivets I removed.

I was missing the two lower plates that are…

Hi everyone,  Richard Young, an aviation buddy, has been at it again trying (and I think succeeding) to be a media star when it comes to our flying interest.  In this 5min YouTube, he has 'nailed it' for those wondering what it's like to have your own, self built 'magic carpet'.

Flying my 601XLB

This is Tangier Island we flew to in August.  It's a quaint village struggling against time and climate change and sinking into the bay.  We had a group of four aircraft for this almost 70 mile trip.  There are many great restaurants and normal tourist shops.  If you go it's short and has many frost heaves creating a roller coaster landing and take…

Stol CH750 poh

I recently purchased a 750 with an O235 in it. I was wondering if anyone else has the same motor and what some of the operating speeds were. The poh that came with the plane was a generic one for a 701. Any help would be great. Thanks.

CH601HD Main Gear Spring/Rubber Bungees and Dual Controls???

Hi everybody just starting a build on a CH601HD and this is my first post, I have a few questions.

I see that Viking makes the nose spring bungee kit, I was wondering if anybody makes a similar kit for the main gears on a CH601HD? or if anyone has made their own I would love to see it.

Does anybody have a kit or drawings for dual controls in the CH601HD? I see Zenith has the kit for the later models but not for the CH601HD. Thanks

Dynon p lead resistors

Hope to solve soon but do any of my fellow builders have experience in the total resistor value needed to solve erratic rpm readings on Dynon HDX unit and Continental O -200? Tried 30k, 62k, 92k, off p lead and the display still goes bonkers at rpm exceeding 2300. Thanks in advance.

Flying DART Exercise (Disaster Airlift Response Team) in my Zenith

This was my second year to participate in our local county's DART exercise.  I flew three missions during our mock exercise last weekend. We deliver food to food banks in the area using donated food as our load for practice.  All loads were weighed and loaded in general aviation aircraft at the pilots direction. I flew 100 lbs on one trip and 75 lbs the second. Took pics of all the bridges on my recon flight. The STOL CH 701 is perfect for this. This really is a good program  and it enhances…

Rudder Trim

I have spent a little time experimenting with rudder trim, and I think it would be worthwhile to share my experiences with the group.  I know that most of you are probably saying "Why?" to the concept of rudder trim for our STOL aircraft.  In most cases, it is probably not necessary.  However, I found it useful.  I'll explain.....

The Aerosport IO-375 makes 195 hp, and lots of P-factor.  With that power plant, one can point the nose up and go.  In the 801, I can also haul a…
