Hello,

I've managed to get about 30 flights out of my stock Axe CP so far, and have tail-in hovering down pretty well. I'm ready to move on to side-in hovering, but the problem is that I'm not really getting enough flight time to get the kind of progress I'd like -- I only get one or two mistakes before the battery needs charging.

Well, the solution is obviously a better battery, and the TP 1320 3S LiPo looks like it's popular and will fit my needs pretty well. However, even on the stock battery, the motor/heatsink and battery itself gets quite hot, and with my flight times hopefully doubling or more with more power, I think the engine might be in danger of becoming too hot.

I've read about the heatsink-dremel mod, and I'm going to go ahead and do that, but will that be enough to keep motor temperature down through an entire charge of a LiPoly battery? Is there anything else I can do? I know brushless motors are a little more durable as far as heat goes and will give more power and longer run times, but I don't feel quite ready for that so I'm looking for alternative solutions.

On a semi-related note, is there any easy way to tell when the tail or main motor is going bad? I'd rather not find out during flight ...

P.S. On a normal 1320 3S LiPo battery and nonaggressive flying, does anybody have any idea on approximately how long a flight I could get?

Thanks!
