Have done repairs no soldering using Black Liquid Electrical Tape and heat shrink tubing, never as good as soldering but does work.

I went thru lots of tail motors on my Blade CP and Venom Night Ranger 3D, so I was wondering about motor issues on these S107G's. My first S107G should be here tomorrow.  I better start stocking up on spare parts so I don't get grounded.

Think i'll just get extra Heli's since there so darn inexpensive.  You get more parts that way, alot more...  Dennis

I found the problem.  The solder joint had cracked and the wire was making a very weak and occassional contact with the board.   Resoldered and flying again.   Thanks for all the helpful ideas.

I just replaced my tail motor. Pretty simple job, really. I'm airborne again! I knew that it was dead when I tried to turn it by hand, and ut felt like there was a dead spot. It would become harder to turn at one point in each revolution. Before you commit to replacing the motor, you may want to make sure that the rotor blade isn't pressed down too far.

I have never had one brake down but this may help.

I've only had one for 3 weeks, but in my research I have read several times it is common the tail rotor motor goes out on s107g's.

The tail rotor motor on my 107 has pretty much quit.  When I try to activate it (forward and reverse), it jerks a little like its getting the signal, but it won't revolve unless I give it a spin with my finger.   The revs are slow though and it doesn't have much power.  The minute I let off the throttle, I can't get it started again without helping it with my finger.   Think it's the motor or the board?    I ordered a tail motor.   Is this a common problem?
