Ok, im confused. An eagle 2 is a highwing trainer with a flat bottom airfoil.

This is not your plane though.

I would guarantee that a 1/3 scale bipe would need at a MININUM A 90 2 STROKE, OR 12O FOUR STROKE ( if its light and slow)and probably much larger.. oops dont mean to shout.
Big motors cost money. Search under GP christian eagle, pitts special. or Dave patrick ultimate. Try to compare size and weight of these models and see what motors are reccomended. These are acrobats and do tend to use motors that seem excessive. Find what is closest to your model and work from there. If it is 1/3 scale you may also need to get some high torque servos and a larger 6v battery pack.
