Default mmm help

Unfortunately I'm having nothing but trouble with my system. I run an airtronics m11 with 2.4. Whenever I have the throttle sub trim to zero I have steering but no throttle. When I put the sub trim to 100 the esc turns fully on but full throttle is applied. Also no matter which way I reverse the throttle it is backwards. I have no clue what's going on please help

Try updating the ESC's firmware. This fixed my similar problem.

sounds like you may need to update the software maybe... ive never had an issue with mine doing this unless my motor wires were reversed.

Quickly can you please just go over the steps as to calibrating the esc. New to castle, just wanted to make sure it is calibrated correctly!

Thanks

max out your EPA's on the TX and zero throttle trim before calibrating.

You have some power or noise issue.

I also run a Spektrum system and was getting glitching problems. It turned out to be my fast high torque Airtronics Digital servo was pulling too much current on the BEC making the voltage dip and the RX was going goofy making the throttle glitch real bad. The fix for me was a "Glitch Buster" capacitor on the RX power. Novak, Castle, and Spektrum all sell them. Look up RC Glitch Buster and you will find a few diferent ones. Any will help. I just bought a few high grade capacitors and soldered up my own with a spare servo cable to plug into the RX aux channel port. Virtually all of my glitching is gone.
