Hi</p>

I have bought that motor combo and have it on a 400 chipmunk (goldberg) I have a variety of 3 cell lipos (zippy ABF) from 15c to 30c and have had no problems with any of them. I have bought all these batteries from Hobby City and they performed flawlessly and they are now over two years old. I would recommend the Hextronik balance charger 2-4 cell (about 30usd) it is an adjustable and easy to use charger that plugs into a cigarette lighter. The rule of thumb I use is this 500-1100 ma I charge at 1 amp. 1200-1500ma I use 1.5 amps. 1500 &amp; up 2 amps. I use a 2200ma pack in the chipmunk (for nose weight) and an 8x4 APC style prop (hobby city) I can fly it until I get sick of flying it on that battery (Well over 10 minutes My transmitter timer is set at that) then I land and still can fly it again. I have also used a 1000ma battery and added lead and got a full ten minutes with out charging. That setup nothing gets nothing more than warm. (That makes things last longer as heat is a killer of batteries and speed controls.)</p>

I am not sure of the weight of that airplane you are setting up but if it is high wing under 2lbs you should be fine. My chipmunk is about 24 oz ready to fly with battery and it is a missile with that setup. Make sure there is good airflow through the motor compartment over the speed controller and battery. This will really help keep it cool and make things last longer.</p>

The 9x4.7 prop is a bit much and the motor gets real hot. (At least mine did.) The 8x4 works much better.</p>

I hope this helps.</p>
