Here's a new Embryo I'm working on. I've built two Big Cats before, one flew into some water and fell apart and the other went OOS. Both had an incredible climb and a decent glide, and would go way up in thermals. I built the tail straight and added a bottom wing spar, but otherwise no modifications.

I'm planning on doing a wing DT for this one, and a carved balsa prop -- maybe something like 7" diameter with 9" pitch.

Hope by now you have flown your third Big Cat. I like the simple design and mine flies just fine.

Bob did you mean that you didn't offset the fins for a left or right turn? What did you trim for - right climb and right glide or right climb left glide turn?

I have one to build and was thinking of right right.

 I fly mine Indoors to the left with about 1/16th fin offset, good fun.

Thanks Dave. Mine will spend it's time outside and I tend towards going right - right. It needs building first!

Mine also flies outside. Usually right/right  turns. Al Backstrum designed it and I knew him in Texas. Went with him to Muncie for the Outdoor Championships a few years ago.
