OK,

So I had this great idea of putting 2 motors on my foamie. I have two 3 cell 750 packs and two escs. I want to use a mix to the motors so that I can change thrust.

Here's my question. If I plug the throttle lead from one motor into the throttle port on the receiver and the other throttle lead into my aux1 port, will I overpower my receiver?

Please respond, may be a goofy question, but help me please.

why would you want to do that?......[X(]

If your ESC's are using BEC (battery elimination circuitry) you should disable the receiver power from the second ESC by removing (disconnect) the red wire between the ESC and receiver. This allows one of them to continue to power the servos and receivers but prevents the two ESC from fighting one another in case the regulated voltage they feed back to the receiver is not the exact same value from each ESC.

Are you talking about the 2 ESC's fighting who makes the BEC voltage for the receiver or something else ? If yes.

Use Rodny's answer.

I have had two seperately controlled electric motors on airplanes.
Pulling the red wire from one of the ESC-to-receiver cables works. ( I actually cut the red wire in a short extension harness, rather than mess with the cable from the ESC itself.)
Then both motors can be mixed to respond to the throttle, or respond seperately.
There's no practical to do this for an airplane, it would be more useful in a boat for fancy manuvering on the water.

A aiplane with a mixer should work.
Use the 2 channels for ELEVONS.

Foward with variable amounts of left and right.

Edit:

If you use 2 Y connectors, you can run a left servo& elevator WITH the left ESC. Do the same for right function.

Just like a Russian.

I am wrong. You would need a 4 channel radio to do it . Left stick channels set up as elevons so they are only controlling the motors ESC's. Right stick other tail surfaces. Sounds better.

Yes, will work. Copy ch 3 to aux 1 then mix some rudder channel into the throttle channels +10% on one -10% on the other. Read the book that came with the radio for the details. Helps for taxiing a twin that won't turn on the ground.

Thanks all! Contrary to the movies, with the old bomb squad guy on the phone with headquarters - I'M GOING TO CUT THE RED WIRE!!!!!!!! I really appreciate the responses!

DaveFlynn

Read the instructions from the ESC first. You may not need to cut the red wire. Castle's ESCs for one work in parallel. It depends on the type of regulator used. I have 2 TB 18's in a GWS P-38, works fine.

My Feedback: (2)

Yep, check with the ESC manufacturer, you might be able to leave both BECs connected, which would provide more current for your servos. If you find that you do have to disconnect one of the BECs, then I'd suggest using a short servo extension with a clipped power lead, so you don't have to modify your ESC connector (you may want to use that ESC/BEC in another plane someday).

Just put one receiver for each motor.
Then you can give the ailerons to one receiver and rudder/elevartor to the other.
It will give you separate juice from the BEC to each receiver/servos.
But don't forget to put the SAME crystal on each receiver !
