Default using two esc together

Prolly a dumb question but is there any reason why I cant use two speed controls on the same channel? I want to hook up two GTB ESC together and run them through one channel on my radio. I'm building a custom clodbuster and I want to have a one esc running the rear motor and one esc running the front motor.

I have never tried it but don't see why not. Just get yourself a y harness used to conect 2 servos together and give it a shot.
You also have to think about the power to your radio gear running 2 batteries and 2 esc's.

could use 2 TEU-101bk's in parallel with a Y adapter and just use a simple 6v battery pack for the RX's power (the TEU don't have a BEC)
that way you don't have to worry about frying your RX with too much current that 2 ESC's might feed it when hooked up in parallel

But that's just a guess.

That is a good point, one of the ESCs (or both) should have the BEC disabled to eliminate cross-currents between one BEC and the other.

Yes, it's as simple as using a y-harness between the receiver and the speed controllers. Depending on the speed controllers being used, the BEC circuitry can be damaged if you do not disable it. This can be done by removing the power wire from the y-harness leads where the speed controllers are plugged in. Doing this will require running a separate receiver battery (6v) plugged directly into the receiver. Since this is for a clod buster, there's plenty of room.

This option modifies a $5 wiring harness and leaves your electronic speed controllers untouched.

ok just to be clear I remove both power wires from each esc where they plug into the y-harness and then add a recv. battery to run the recv and servos.

or you could just unplug one of them and use the other as it normally would be used
