Tail rotor issues Falcon 40 electric

[newjack]

Bought my first helicopter, a "Falcon 40" about two months ago. Current problem: the tail rudder no longer has sufficient authority to counteract the main rotor when the heli starts to climb (even with full right trim). Burnt up one tail motor before this, is it possible that the new motor is tired (partly burnt)? or is the helicopter brain not sending enough juice to the tail? I've replaced the tail gear b/c I though it might be slipping (didn't fix the prob). Any suggestions?


Thanks,
Isaac

Oh, and the reason I haven't switched out the tail motor again is it seems to have the same amount of power it used to (spinning it flat on the ground for example).

also posted this on the "electric" forum before I found this forum

You should always "break in" brushed motors.

Take a small low volt battery pack 1-4 cell NIMH run the motor (with no load) for 5 minutes.
Then Switch the polarity and run it again for a few minutes

this will break the brushes in evenly,lengthen the motor life, and increase the performance of the motor ;)

hope this helps

Thank you, will do that when the new motor arrives. Any website that sells motor heat sinks? It's 110 out there...
