I have an ESKY V2.

I <span style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Times New Roman'; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; font-size: medium;" class="Apple-style-span"><span style="border-collapse: collapse; color: rgb(51, 51, 51); font-family: Verdana,Arial,Helvetica,sans-serif; font-size: 12px; line-height: 19px; text-align: left;" class="Apple-style-span">had to replace the tail motor.<span class="Apple-converted-space"></span>

Having done so, I cannot get the main and tail rotor to turn using the 4 in 1. The pitch/roll servos work fine.<span class="Apple-converted-space"></span>

The 4 in 1 flashes alternating red and green, then the light stays on steady red. I have tried multiple rebinding with no success, so what does this red light mean?<span class="Apple-converted-space"></span>

(The main and tail rotors both work together using a different receiver.)<span class="Apple-converted-space"></span>

Any ideas gratefully received.

Thanks

Resolved!

Have obtained advice from the forum at Heliguy.com which is well worth a visit.

Did not have the throttle trim at idle when connecting. Once this was changed, the heli worked fine.
