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.…

STOL 750 final wing assembly

The Slats attach with simple clecos alignment was all set through the pre-drilled holes.



The fiberglass parts aligned well and installation was simple fare.



THE Rudder is installed as is the stabilizer. Stops and alignment is done the same as the… Continue

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

A quick trip to Washington and back (Another 1,330 miles for the log book)

On Friday I flew 664 statute miles from Santa Rosa, CA to Shelton, WA to visit my brother Alan and his wife Nathalie who have a Zodiac XL which is a twin of mine. The flight north was one of the more challenging I have experienced. In Northern California I got to choose… Continue

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 !…

UL260i? Yeah, its really that light!

Our ULPower FWF kit is coming together. The cowl will be back any day now. As you can see, the engine hangs out there quite a ways. Much time was spent on determining where the engine should be located to make the CH650 remain in CG with about any possible loading scenario. The engine comes in at 170 lbs. with prop, baffles, and oil. A very light 95hp, and now there is a high compression 260 that burns 100LL and is 105 hp. The empty weight of the 650… Continue

750 Panel Parts in Particular

As our deadlines approach, many things are coming together. Installing the fuel tanks is all that remains of component building. The panels is finished and is on its way to being mounted permanently. We have an MGL avionics Enigma EFIS/GPS/engine monitor and their new V-10 comm radio. The V-10 weighs almost nothing and interfaces easily with the Enigma. The Garmin transponder and a Van's (sorry) map box complete the… Continue

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

What is your experience using automotive gas in airplanes?

I fly a 601XL with a Jabiru 3300 engine. The other day I ran into an old-time pilot who has been using automotive gas in his airplane for many years. He reports no problems, in fact he had only good things to say – like longer engine life since he switched. Jabiru does permit the use of premium auto gas in the 3300. I am contemplating the switch for the following reasons:



1) Longer sparkplug life. I have gotten 170 hours out of my last two sets of spark plugs which is hours 70 more… Continue

Testing Phase 1

After 205 inches of snow this winter, I'm finall able to start knocking off some test time on my 601 XL. I flew the 11th hourof testing this arternoon. What a teriffic airplane ! I'm getting more at ease in it with every flight. The Corvair is running strong, and I'm seeing 1000'+ climb rates with my 190# and full tanks. I initially had to adjust the horiz. stab. angle down 2 deg. I'm still tweaking my cowling a bit to improve cooling at high climb rates. The flaps are a real asset on the XL,… Continue

701 Scratch Builders Compare Ideas

I'm very close to first flight after 5 years of building. I wish Zenith would have had this site up and running 5 years ago. I have learned alot from other builders. But scratch building has its own world so I'm creating this blog for scratch builders (701), such as myself, to have an avenue to share ideas (and frustrations). The feeling of success in your building is well worth the frustrations that are mostly unavoidable. So just share what your going through right now and don't be afraid to… Continue

Back to Wings

Back side of the wing, the rear spar is a two peice affair with a doubler channel, this makes assembly quite simple and fast. Best part is the trailing edge being a bent unit which makes the trailing edge very attractive.

Front skin cleco's right on.



Look close at this picture, the amount of time that will be saved in slat alignment from the… Continue

601 HDS Move radiator rearward or fit front undercarriage stop?

I am finishing a 601HDS that is fitted with a Subaru ea81 motor. The water cooling radiatior is fitted under the fuselage, close behind the front undercarriage. As there is no stop on the front undercarriage, it is possible for the wheel spat to impact with the underside of the radiator.



What is the best solution to this problem?



I have contemplated fitting a pair of steel cable stops to the front undercarriage to limit their travel and also to relocate the radiator… Continue

Another Fun Factory Workshop

We "graduated" another class of proud new aircraft rudder builders today:

Despite the apparent slowdown in the economy, this group was proof positive that there's still optimism out there and that folks still want to have fun building airplanes. The full workshop (12+ rudder tail assemblies of both STOL and Zodiac designs) included six husband / wife teams, plus four father / son teams, and was a lot of fun (even for the organizers). The… Continue
