A question for the guys that have a handle on electric flight....

Oops... forgot some critical info: the packs are seven cells.

Thanks again, Bob

If you have the money go for brushless. You need a new esc. Hacker is the best. shulze has also good stuff. spend between 300 and 500 $ buy some GP 3300 Cells. (7 * 6$ ) Check your charger, not all chargers are suited for NiMh cell . ifso stay with 2400mAh Nicd cells.

If money is a problem just go for 3300cells and a hotter motor.

If you don't have the money,LIPO cells wiill net you about 70% increase in power to weight, and give longer flight times for less money than a brushless, which will net you 25-40% increase in power to weight, and probably no increase in flight times.

Check out the AstroFlight.com website -- sticking with what you hve for an ESC, an ASTRO Cobalt 05 is close to the mark (going into my next eStreak). If you want to go brushless, I'm not sure but a quick run of MotoCalc will give you the motor that works for waht you ahve ($$$$ thought)

Thanks very much for the tips!
