look the video of engine and motor in rc universe and look for brillelli GT and Yak , this is the setup I got with a 40CC you need the extra weith in this airplane on the nose, this plane is tail heavy, and use a pull pull system on the rudder, the landing gear is from a great planes ultimate 1.6 and is only 14.00 dollars from towerhobbies and fit perfect you only have to relocate one blind nut on the gear and is composite, even the plane look scale. I use a hitec 805 for rudder because I fly 3D. the plane fly 3D fine with this setup, and super powerfull for Imac.
