Hi There
46os that a gas engine Right
You will get better response if you were to post in a gas plane section.
This Section deals in ELECTRIC power.

The section your looking for if you haven't already found it - Aircraft - Fuel - Airplanes

If you haven't flown before, putting a bigger engine in a model just means you have a quicker way of destroying it.

With a trainer, the last thing you want is a more powerful motor, because it will be heavier, so it will need to fly faster to stay up. Plus the heavier the plane the harder it crashes! Butch
