XK K124 『3.7V⇒7.4V』Vol.2 送信機設定 Transmitter settings 

☠BLACK BARON☠ Hovering all the time is very battery intensive. You might get longer flight times with pitch forward flights.

Hi mate, i have a 14 months old K124 and it has flown greatly over the period. However recently i had few crashes due to tail motor blow out. Swapped to a new tail motor, and with this one, after i spool up about half throttle just before took off, the tail motor kind of whined for a split second and kicked the tail to the left (heli nose turned to the right) and both motors will stop spinning. If i cut down the throttle then spool again, the rotors will start spinning again. What could be the problem? Is tail motor or faulty PCB board? Thanks in advance, appreciate your help.

ヘリも安くなったから何とか手を出せるようになったよね！

すげーマニアックw
