Tsands,

I'm also thinking of buying a sonic 25 low wing plane soon. I also have a 25FX laying around. I've seen it fly on both a .32sx and .25 bushing I beleive it was... The plane flew well with both engines, the 32sx being a little to much. But apparently they fly really well and land very well too. good second plane.

Anyways, let me know how your sonic flew with the .25fx I would really appreciate it!
