The ESC 25A means how much power (amps) speed controller can handle. And there are also speed meters for the airplanes http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=6778 orange68

PostSubject: Aircraft speed and size   Tue May 05, 2009 11:19 pm

Hi ayman,

Your question is an intersting one, in that if you just look at the size of the engine alone, that can mislead you as to the speed the plane will want to fly at. When I learned how to fly RC planes, I got an Eaglett 25 and it took a small engine. So after I built it and flew it, with help, this thing was pretty fast to try and learn on.

After that I got to fly a 40 size Eagle, much more docile, easier to control, and slower, yet the plane was twice the size and had twice the engine in it.

So, don't just go by the engine size alone. A lot of sport models are small, with small engines, and they are quite fast in the air. If you have a good local hobby store near you talk to the folks in there and tell them if your looking for a trainer or what you have in mind. Engine size alone is not a good indicator of the relative speed the plane will want to fly at.

Hope that helps,

Tristar
