John they are available in Trylam, a far superior product to Dacron but an optional extra. The Blue Cheetah is in fact covered with Trylam.John Young wrote:Don't think that they are available in anything else?
I came from a Short wing Challenger, and at that stage I installed doors . Now let me tell you about adverse yaw

The problem with adding large winglets and extended vertical stabelizers is it detracts from rudder authority. I would have no problem with a Cheetah without the winlets, having come from the Challenger.
If you ask my opinion, I would buy the Cheetah, really great planes
