A B1R will not work with a Holmes Hobby 7T Cobalt dude. 380 size motors only!

Also remove the signal wire off the CC BEC to eliminate problems.

Kinda mis-interpreted the whole specs on the drawing I pasted. I'm using the B1R ESC's that Tekin donated for the Active Kids program and their 55T motors. I'm also using the CC bec's, and 8-cell NiMH batts.
I removed the red wire from the ESC's reciever plug only and it seems to work ok after last nights shake down run.
Should I still remove the reciever wire from the BEC as well? (not to sound dumb, but which color wire is it? I'm trying to be very careful and route everything as professionally as possible. I'd like to make sure it's right so as not to burn up "4" rigs that are full of the best parts (mostly) that vendors and sponsors have donated to. Thanks for the help.

Wired it up per CC's directions and kept it clean lookin'.The B1R is silly small but really packs a punch.
Thank You Jim, and the rest of the Tekin crew for the goods to get these Kids Crawlers going. Hope it brings a bunch of new buyers to your door.

Ok tell me if this is normal I've been running my B1r for almost a year. I installed a robotic servo rated for Lipo power. I'm only running a 2 cell LiPo 8.4v. So I hooked up a lead that goes from the battery to the RX, so I should be getting 8.4v to the RX on a full charge. I did not disconnect the red wire from the B1r (didn't think it would matter on a 2 cell) and 2 min into my run, poof it fried the B1r. I'm assuming that if I would have disconnected the red wire it wouldn't have fried? I really thought that I'd have issues with the RX or servo from over volting not the ESC.

Any help?
