I have started looking at my Futaba 8UAP for programming a three engine project. Later I will be looking at a JR 8103 for similar capabilities for a friend.

Here is what I would like to accomplish:
1. Top left corner switch shuts left engine down to 4,000 RPM and un-slaves engine. It’s the E or gear switch on my radio.
2. Top right corner switch shuts right engine back to 4,000 RPM and un-slaves engine. It’s the G switch on my radio.
3. Left pot (channel 6) changes the differential between center to left outboard. Left engine = channel 6.
4. Right pot (channel 7) changes the differential between center to right outboard. Right engine = channel 7
5. Throttle trim trims all three engines.
6. Sequence shutdown will be by trim pots.

Someone might already have experience and know the pitfalls. Any advice will be appreciated.
