Hey, guys I just joined. I'm trying to wire up the radiomaster ER5A with the Flite Test FT Power Pack B Radial v.2. I've managed to bind it to my receiver using the ELRS phrase. But my issue now is that my motor is not responding to my throttle stick (the left stick). Instead my motor is responding to the right stick 'Ail' signal from my receiver. (aka moving the right stick leftward). It will then make a double beep, move a tiny amount and stop. My servo works just fine when I move the right stick up/down. Nothing happens when I move my left throttle stick.
I have a radiomaster Tx16 with internal ExpressLRS module.
Appreciate any tips! Thanks!
