If it won't arm;

- rx cant see the tx
- 3-in-1 is seeing throttle input
- 3-in-1 not seeing any signals from main and/or tail channels

For #1, clean the rx pins. Put a kink on the legs to grip better.

For #3, open the 4-in-1. Split apart teh rx pcb and the 3-in-1 pcb. Clean the exposed pins. Reassemble the 4-in-1.

Other than those you are looking at replacing parts.
Turn on a dime. Flip like a quarter. Feel like a million bucks.

Looks like the throttle pot on my tx is toast!!This is good news though,as now I can get the new tx I've been saving for,just a little sooner.This is perfect timing anyway as I started building my MINI TITAN on Thursday and now I can use my new TX for both!!!

I put the pot on the meter and it was dead, took it apart to confirm and the contact strips have worn away
