Cowling and mounting the Rotax 912

As you can see below the cowling had to also be extended, in order to expedite the process Zenair installed a metal strip and added the fiberglass to that. They are working on extending the mold now so that future cowling's will not have the metal strip.

With the motor attached to the mount we can re-install it back onto the fuselage. Though you can actually lift the engine by hand the cherry picker… Continue

First real result of the NTSB report

I was scheduled for a CFI-SP checkride tomorrow. I'm all ready for it. I've been boning up on all the stuff for the oral exam, which is reported to be a bear.



The DPE who I'd scheduled the ride with told me she wasn't comfortable flying in a Zodiac, and postponed the ride until the issue is better understood at minimum, and ideally resolved.



I understand and respect her decision.



I'm still annoyed, not at her, but at the whole situation. I've spent 6 months… Continue

End of Winter

Finally the winter is giving up and spring is on the way, looks like we can get back to work and finish the 801. We will be doing the weight and balance on thursday the 16th of April and then it will be on to organizing for the FAA inspection. Need to make sure all of the paperwork is in order and ready before asking the inspector to come. This has been a long time coming and I am looking forward to finishing the project. We have our annual ABC Supply SW Airfest coming up next month and it… Continue

Elevator Tip & Nose Rib Fluting/Crimp Dimensions

Re: Parts # 75-T-3-1 & 75-T-3-2. Caleb emailed me a .pdf file showing the crimp locations this morning. I'm impressed with how fast they got back to me. Thanks Caleb! I'm not sure if or when the updated drawings will be available on the Zenair site but Caleb has them if any other scratch builders need them.

June 23rd update: The new updates to the plans have the dimensions on them.

CH750 is nearly in the air

A big day on April 13th as we pulled the CH750 out of the hangar and started the engine. The 0200 roared to life and sounded like a million bucks. We ran the engine for about 15 minutes, then shut down and back in the hangar. The last remaining items are so simple (and small). I have three bugnuts coming from Spruce to attach mixture, carb heat and cabin heat. I safety wired everything last night. Once the bugnuts are installed it's time to weigh, complete weight and balance exhibits and submit… Continue

Finally got to taxi it

After nearly two years of building, I got the engine running, and taxied it around the airport. Pretty exciting. I am about ready to have the FAA bless it.

STOL 750 Flapperons

ALignment of the Flapperons took a bit of time and required more then one hand. I used a 20 mm spacing from the trailing edge of the wing to the leading top edge of the flapperon while in a semi neautral position. you can double check by rotating the flapperon and the 20mm gap does not change through rotation.

Here is a pictrue of the slats attached, the bent edge makes for a very clean line.…

601 Flying Carpet

Getting more time in on my 601 XL / Corvair. Cruised about 100 miles Sunday, 3000 RPM, about 110 MPH TAS at 5000 MSL. The air was smooth as glass and the Corvair never missed a beat. I've been tweaking the cowling to improve cooling, and this flight saw about 230 deg. oil and 350 - 370 cht's. I'm running the Ellison carb, and pull the mixture back just enough to bring the EGT's up to 1300 - 1350 deg., using a Cyberdyne mixture meter for guidance. This Zenith flies like a dream, and turns a lot… Continue
