.25 sized 3D's?
I got a giant scale planes cap .25 and it isn't the best for 3d. It is too heavy and it comes out tail heavy even with a big engine.
The person who owned it before me crashed it once and repaired it and never liked it. I bought it cheap and put an enya 35x heli in it. I added standard servos and mounted them inside the fuse. I did get the CG to be on the spar and it flew a lot tamer. I recently moved it between where I thought the cg should be and their recomended place and it flew good and was tail heavy like I wanted.
I liked the plane a lot and had fun with it.
