I have an nice older pattern aircraft. It's a Desafio II and I'm not 100% sure of where the CG should be located. Does anyone have one of these or a set of plans they could look at to help me out on this? I tried using several of the calculators available on the web and got conflicting dimensions. (Also posted in the newer pattern forum)
Thanks -Bill

Hey Bill,

I don't have a Desafio II but I do have a Desafio S kit (that I got for an absolute STEAL on a popular auction site!) I don't know the relationship between the two but I can tell you what I know about the S version.

The wing chord at the root is 16 3/8". The plans show the CG as 8 3/4" forward of the TE of the wing. If your wing is the same chord, that is probably a good start.

This is supposed to be an awesome aircraft! I think the S model took third in World in '94 or so. What kind of engine do you have in yours? I've got a Thunder Tiger Pro 1.20 RE lined up for my S model.

I have the plans and instructions for the S model. Give me a holler if there's anything I can help you with. And most of all, please let us know how flying this plane goes. I'm hungry for info on this plane!
