BD-5 repaired (0 min 11 sec)


Heat shrink tube for motor to ESC plug.

Change propeller to GF 6*4E soft than APC 6*4E and much cheaper, no vibration more smooth.

Wait for next Monday morning test flight...

BD-5 suddenly lost power crash (0 min 19 sec)


I guess when add motor angles cause the motor to ESC plug loosen.

Add motor angles seems more easy to take off, or because after rain the grass more smooth.

Change 3S 2200mAh to 3S 2600mAh and add balance lead, total weight become 690g, m
Look like head heavy. No chance to test it.
