You're going to need quite a bit more power than what you can get out of a 7-cell 1000mAh battery. The laws of physics say that to overcome gravity and drag, you need X Watts for Y weight.

.25-size conversion are in the realm of 10-cell, 3300mAh NiMH battery. You might be able to get away with 8 cells and a brushless motor, but the cells still need to be the large 3300mAh size to sustain the high currents necessary.

At around 4 pounds, you'll want at least 300 Watts. One inexpensive power system is the "Gary Wright E3D" power system that I've recommended many times in the glow to electric conversions forum.

Practically any hobby shop, local or online, in the USA can get it for you if they don't have it on the shelf. Kyosho is one of Great Planes's major brands.
