About the BEC, did you try running the two speed controls together, or just asked the manufacturer about it? Thanks for the update and info.
I am waiting for the 2nd tekin rebel2....
_I am ready to install it.
....and in the meanwhile.... I smoked the BEC circuit of my single tekin rebel2 .
I was steering ONLY with the 5955 and a Futaba 9402 (110 Oz at 6V) in the reAR .
STRANGE BUT SADLY TRUE.
the esc is working . the bec circuit not at all, now.
Bye bye.....
