Wing attach

IT is nice to have help in the shop during the wing installation. Here we see Ryan using his head and after some whining we installed some foam cut offs from the seats on his head.

Wing installation is quite simple, install main spars to cabin frame so that they are centered and equal on both sides, then drill with a 1/8 th drill bit. Leave drill bit in place an repeat for other main spar, once again leave drill bit in place, this locks the spars… Continue

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

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.…

Sky Hummer 750 with Rotax Cowl

I told my Son that the 701 is called the Sky Jeep, he turned to me and stated that if the 701 is the Sky Jeep then surely the 750 is the Sky Hummer. I laughed and told him not to call me Shirley, but Sky Hummer is going to stick for the 750 in the Hanger.

I couldn't wait so I installed the cowl just to see how she is going to look. I like what I see! Alot !…

750 Wing Final

Inspection is over and I did not take time off to relax, I tried, wife let me sleep for 10hrs then I got up and found that my mind was too much on the 750 to be able to read a book. SO I got back to ordering parts for the panel and the wings. THE pictrue above shows the final installation on the bottom of the wings which is the strut attachments.



You really have to see it to believe just how flat… Continue
