help, mini dragonfly

Hi

I am new to helis and I recently bought a mini dragonfly. The problem with it was that the back tail rotor stopped turning. It worked at the beginning and has stopped now.
Please can you help me

Thank you

hello, i had the same problem. i think it is because the motors are not really broken-in on the first few flights, and if you push the rear motor it will wear out since they are quite fragile. i have replaced the old rear motor with a slightly bigger one, and i have had no problems yet. you could always buy a heat-sink. they really keep down motor heat and extend their service lives.
