THanks for the input on the throttle. I TH ink I will settle on this for owner
http://www.aircraftspruce.com/catalog/appages/a820.php
A-820 CONTROL 36" BLACK KNOB 05-09436 $50.50
They have 11 in stock locally here in Canada and I can cut to length.
Thanks again for inputs.

PAt, I would have to look but I think the models 1 to 3 are a bit different than
the IV model. Something tells me that is like 12 to 16 range.
I got a model 2 manual in shop, will look and let you know

Luis ,
That kind might work but I think suited for the 912s.
The 582 have a bellcrank up front that joins the 2 carbs and the oil injection
cable. Only needs to be about 2 feet long or less.
Thanks

I too went with the Vernier throttle because the friction adjustment would
not hold the throttle position very well on the old one. I always had to
tighten it. The Vernier was much better but on a few occasions I accidentally
hit the center knob with the palm of my hand and ended up going around on a
short strip as the engine went to full power because of the carb springs
(Vernier disengagement)
I now have a counter balancing spring going from the throttle bell crank
to a spot next to the Vernier attachment point at the throttle quadrant. It
is a long automobile throttle return spring about 10 inches long. I now have
a perfectly balanced system. I can push the Vernier button in and the
throttle will advance very slowly or not at all. It's GREAT! just like a "normal"
throttle system. Thanks to Lowell Fitt for this idea.
This particular solution will not work if you don't have the older
bellcrank system but perhaps you could come up with something similar.

to the model 3?
Pat, you should get someone with a model three to verify this information. For
what its worth, a weight and balance program I downloaded years ago from the
old "Kitfox Builders" website uses the same arms for the models 3 and 4. The
forward CG limits are the same. The Rear CG limit is different. For the Model
3 this program lists 14.28 inches.
If I remember correctly, the old skystar factory did some additional testing on
the Model 4 and increased the rear CG limit to 16 on the Model 4 only.
I'v always wondered if a person could do an empty weight and balance, then do several
more weight and balance with a known weight at each of the loading locations,
then run the math backwards to find the Arm for each location???

| Subject: | Re: Kitfox 7SS w/Corvair Engine |
Thanks, fellas for your help. While Brady thinks a corvair on a fox
would be possible, listening to you, the builders, suggests that the
result would likely not be good. May just have to look to the
Jab3300 or Rotax 912ULS as better though much more expensive
alternatives. Thanks again.

Tom, Thanks for reply. I since have found an explaination of computing the
CG envelope using mean avg cord of the wing. It was in my builders manual.
It also listed the Mod 4 forward cg as 10.2" which followed the formula of
20% of MAC. In addition it listed the rear CG as 16", 16" does not follow
the 28% of MAC. formula. The 14.28"is 28% of the 51" MAC. I had heard that
the factory had extented the rear CG after tests., and wondered if it also
applied to the model 3. Thanks again.
