It's certainly going to be an interesting challenge getting the power balanced!

Looks like you are using the same transmitter i use...Great product!
I sure do.
They are a brilliant budget price RC radio TX!Trying to get the power differential thrust balanced while using two different manufacture brushed ESC's has been a nightmare. I think this challenge may have beaten me, and it'll maybe end up with an aileron servo. 😪

Whats your problem with it? I have figured out quite a bit with the FS-I6 and the FS-I6X......
I've used differential thrust a couple of times before with my twins and had no problems, but this is with brushed motors and different esc's. Different manufacturers, and one is a 5A the other a 10A. They are not behaving the same, the power they are putting out isn't balanced as the throttle is opened. I balance the thrust in the mix but the thrust changes as you open the throttle. Impossible to control a plane like that. You need constant thrust level apart from when I use the rudder channel which is the slave.

Suggest taking esc's and controlling them motors as designed: one left and one right for each esc. Motors need to be in same position inboard or outboard. Difference in power will tend to cancel out but should still act normal unless youre using two channels for motor then it's a mixing control issue in the TX.

Try calibrating them together, I know I had that problem with my esc's (though I had tow of the same ones) They weren't starting up at the same time.

If connected without mixes thrust appears to be the same. Anyhow finally last night in one of my many variations one of them gave up and was hot, so I have a matched pair on the way now. We will see how I get on with those.
The ESC's are set up with one channel for left motors and one channel for right, the idea being thrust is changed by using a mix from the rudder. I've used that successfully with brushless motors on my twins before.
Anyway, I've managed to burn one ESC out in my tests so have a new matched pair on the way now. With luck I'll have more success with those.
