RE: conversion from.25 to electric help?
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.
