Wow thanks Grant for clearing that up, I got up and running for a bit today.
Yes, I'm using 3.0.1. I have a Spektrum DX8 for my radio and a Sony Xperia Z4 Tablet for running Tower. I'm running a 3DR PPM encoder for the RX.
I had a bunch of problems with the arming checks and I am not quite sure how to arm in MP, so that's why I took them all off and I'm fine arming with just the hardware safety switch. I plan to go back and revisit as I understand the settings better.
You were totally right about the RC_MAP. I changed them back and the throttle and skid steer worked fine, albeit on odd radio sticks. I tried to change them in MP, but they didn't seem to change after a few restarts.
I manually reversed the throttle setting on my radio. It now works as it should on the left stick.
The rudder was a bit trickier as it was on the right stick for up/down. I had to manually switch the plugs on the PPM encoder for 2 and 3, then it worked fine. Right stick-left/right.

1. I need a bigger battery. Going to go get a large 12V marine battery.
2. Mount the sonar unit.
3. I'd like to get rid of this DX8 Radio and upgrade the Pixhawk radio to an RFD900 and use a Logitech 310 gamepad with the tablet. What are the procedures for getting that to work with tower?
