Rodo,

Good point!
Will do.
I'll re-do all soldering on this controller

I swapped ESC from sev2 to this heli, both YEP 45a.
Will do the test tomorrow
Not ready to spend money at this time.

Thanks

I had the same problem. Ended up being the ground wire from the BEC was almost frayed through. It was hanging on by 3 strands of wire. I put a new plug end on, added a cap, and wire mesh to protect the wiring. It worked great. I would check all the connections from battery to bec to esc to rx to servos.

I'm using both the YEP 40A and the YEP 45A on 6S with KST DS215MG's and the Tarot 450MX. I'm not using the BEC on the 45A, as I'm running that heli HV. Both are working well, but being 6S, the motor amps are probably well down.

it strongly depends if the YEP is a v1 or v2 version the old one doesn't have problems at all while the v2 version seems a problematic ESC for a lot of people. I have several YEP's v1 versions on my heli's and they never failed. 3x40A, 2x45A, 1x80A all using the internal BEC
