otto you have mounted the two engines like me?
Similar. Mine are on the shoulders with counter rotating propellers. I use differential thrust for yaw control. I really like it.

I use a 6 ch receiver with my DX8. I plug one esc into the throttle and one into my aux channel. I have one mix that ties the aux to the throttle at 100% that is always on.

I switch the remaining 2 mixes with my landing gear switch. This lets me turn the differential throttle on and off. These two mixes are rudder to throttle and rudder to aux. I mix both at 50%, one negative and one positive. When activated the mixes advance the throttles to 25%. So at idle on the throttle stick you have 25% thrust on both motors with a differential thrust range on both motors of 0 to 50 percent using the rudder stick. At full throttle both motors advance to 75% with a differential range of 50 to 100 percent. This way both ESCs stay between 0 and 100 percent. Mine recalibrate the zero point if I go below the 0 percent point.

This setup generates plenty of yaw. I generally launch with differential off then switch on in the air. I have a transmitter warning to remind me to have the gear switch in the right position when I turn on the transmitter.

That's where controllers with fixed endpoints are better. You can easily mix to only subtract with rudder. That way even at full rudder you need throttle too. Safer when you do it for ground handling on a twin.

You're right. I'm too cheap for my experiments.

That would be fun. I always resisted this design because of tail weight. All my calculations indicated I'd have to put a lot of lead in the head.
