sometimes, it doesn't really matter what glow size engine was in there....What matters is what kind of performance u want and the AUW of the plane.

I had a Model tech extra that uses a .25 glow engine. i put an AXI 2820/10 and it flew..but it didn't have unlimited vertical and needed to be flown around 3/4 to full throttle all the time. Its now going in a Mini 3D. The extra is on the shelf.

TTYL,
Andrew T.

If it is a trainer .25 glow plane it can be converted with a cheap 16-17 turn car motor and a 3:1 GB. My dad made a Avistar fly on a 17 turn rc car motor and a gear box. It is a giant slow flyer but it flys.

What are you thinking of converting? What is the wing area?

I have a TT Slow Tiger 51 that was rated for a .25 and did a conversion with Mega 22/20/3, 2.5:1, 12-2000's, and 12x6 prop. It has a bit more power than it needs but is not a "prop hanger."

I also converted a Seniorita to Aveox 1409/2Y, 3.7:1, 12-2000's, and 11x7 to 12x8 prop. Still floats nicely and doesn't fly "heavy."

I guess it depends on your budget too. The brushed motors will also work well, many with 7 - 8 cell packs.

Just put the specs in a program like MotoCalc and run with it.

Keep 'em hummin'

I'd be surprised if the plane flew at all if you just put in an electric motor

The most important part of the electric power system is the battery. If you don't have enough Volts and Amps available at the battery, it won't matter how big the motor you put in is.

I generally regard .25-size airplanes as 10-cell conversions. 10 cells at 40 Amps is 400 Watts, plenty to give a plane that weighs up to 4 pounds healthy aerobatic performance.
