Personally,

I dont think that the light motors will do it justice. For 3D you will need a gas motor. Maybe you should put a G-38 on there. I have one on mine and its just a site to see.

[:@] This is one of my biggest R/C pet peeves...Guys that put gas motors on 1.20 sized and smaller airplanes and wonder why it doesnt 3D all that well.
