I hope this is not the Belgian Lazer 3D. If it is you are way over powered. This plane was designed for a 46 2C. I have one with an OS 70 on it and that is overkill. I get off the ground in less than 3 ft and have vertical at 25-30% throttle. Having said that the power is just right and the plane is a blast. 13 X4W APC prop.
