i had a little scare a few days ago ..i would fly my yak up , cut the motor to glide for a while then when i try to turn on nothing would happen[X(], but steering worked so i had to glid it down and land on top of thorns lol ......
but after trouble shooting i realized the throttle trim was set to +20 which was confusing my 20 amp esc and motor so after i put trim at 0, the motor has come on everytime ...
fixed!

.....just my experance with this esc so far
