N20 Carbon brushed tail motor 8t:



N30 Carbon brushed tail motor 10t:


Pros:
Easy to install and inexpensive but over time will cost more than a brushless motor.

Cons:
Requires heat sinks, lasts about 30 full flights on average, generates a good amount of RF Noise.

This is the current standard tail motor found on many simple 4-channel single rotor electric helicopters. This tail motor does it's job decently. It typically comes with an 8t pinion or 10t pinion. It has a decent voltage operating range from 1.5v to 15 volts typically. The average life cycle is about 30 full flights before needing replacement.

Ways to increase the longevity:

1. Add a tail motor heat sink. Typically I use two or three as the heat sinks are skinny. X-treme productions sells a tail motor heat sink that is wide enough to cover the tail motor.

2. Tail jerking results from the tremendous RF(Radio Frequncy) Noise that gets generated. On the Excced Falcon 40/ Walkera #4, the noise causes random tail jerks when in flight. This can be minimized by getting a line filter and inserting between the Tail Rx input and the tail motor connector.
