hi i built a super decathlon it is very tail heavy are these planes just that way . I put a saito 150 in it thinking that was enough weight but i guess not it looks like it will need 1 pound of weight or more thanks.

You didn't say which design/kit. I expect it matters. I built a Dynaflight SD and it was tail heavy. Had to add significant nose weight even though I was running a Quadra 42 with mag ignition. Still flew well all was said and done.

Move everything as far forward as possible. After that, it takes as much weight as it takes. Just add it and go fly.

thank you all for the info i just added the weight and balanced it .
