Both wings were sanded with KF4 airfoils. When I rebuild it I will probably make the front wings almost as large as the rear. The power to weight was good. It was fairly light. The fuse was only three pieces of green foam in a triangle configuration. I had used tape on the inside to hold it all together. During a motor test, it had enough power for vertical flight. The next version will be better, maybe not a success, but better. Thanks for all the input and suggestions. I think we had the CG to far forward. Normally with forward swept wings, it is farther forward. We didn't want it to do the nose up no control thing.

Here's a reliable Centre of Gravity calculator for canards:
Sorry I "cannot post links until I have 10 entries on here", but you should find it if you go to :
adamone (.) rchomepage (.) com (/) cg2_canard.htm

I do lots of scratch built canards and never without the CoG calculator.

Looks promising: Good luck

Thanks. I will give it a shot when I start the rebuild.

your problem might have been your canards were reversed. you probably already know this but your canards have to go down in order to pitch the plane up.
