I'm in the process of building a model c Avid and want to find a lexan turtledeck for it. Were the early Kitfox turtledecks the same or am I limited to finding one for the Avid only?

you could make your own lexan turtledeck from flat lexan sheet. if you have the turtledeck from the avid you can use it as a pattern or make your own pattern using card board.
once you have the pattern you can put the flat sheet in a metal brake to form it. if you don,t have a brake large enough do as i do and take it to a local sheet metal shop. you can find lexan at glass repair shops. hope this he;lps
Be careful with too much heat. Lexan absorbs a relative high percentage of water. Heat too much over boiling and the internal water will do just that and give a cloudy appearance where heated.
Since I just finished a Lexan project and am in the middle of skinning my doors, I took a piece and ran it through my brake. The bend was to about 110° or so. I found that to be a little more than needed to maintain 90°. there were no cracks or craze lines. Photo attached.

Hey HighWing;
How do you heat such a large piece of Lexan even enough to bend it?

I bent mine cold.
8 years and no cracks yet.

Good question, Roger. That is exactly the point no heat necessary. I forgot to mention that. I have heated Lexan for vacuum forming, though and to answer your question, my capacity is only about a square foot or so - I use my wife's oven when she is out of town - safer that way. You have to bake at 250° for a couple of hours to dry, then take up to forming temp and presto. Check my Avitar I formed the lenses for the internal wing tip lights using her oven. Got them on my new project too.

i am in the process of installing the turtle deck on my ss. i have the all lexan t/deck. do the sides and rear just lap over, or do you have to trim it to fit the fuselage?
I've bent a lot of lexan for safety guards on industrial equipment and never had a problem bending cold in a brake.
