Rctimer 30A esc cutting out with KK board

I've had a problem with HK SS 25A programmable esc's stopping briefly due to them not keeping up with the signal speed of the KK blue-boards. I changed the esc's back to the old SS 45A ones and it worked ok. That was 3 weeks ago.

Time to build a hex. I ordered 6 rctimer 30A esc's http://www.rctimer.com/index.php?gOo...6&productname= as others have had a great run with them. 1st flight in the park tonight and the motors all cut out for 1/4 second just like the SS prog ones. I sat the hex on the ground under power and it did it again. Definitely the same problem.

Anyone else have this problem with recently bought rctimer esc's?

If you have the red wire from more than one ESC connected together they will do that. I had several crashes before I figured that out. Cut the red wire on all but one ESC – I use a servo extension so I don’t have to modify the ESC.

Yup - tried that thanks!

All red wires were cut and the esc's were programmed with a ubec. I use a separate ubec on-board the hex.
