I was gonna post this on RCGroups, but I thought I'd post it on Castle's favorite forum instead
I did the most recent firmware update on my TB54, there was a popup that said something to the effect of "this update is not reversible". A bit concerned, I decided to do it anyway. I am regretting it big time. My outrunner just shreiks, jumps a bit, runs a bit then back to shreiking. It appears the ESC can't decide which direction to fire. Thinking it might be the motor, I put in a small inrunner w/gearbox, same thing.
The 2 motors I tried are:
Ammo 24-33 2500 kv inrunner
Waypoint 3014-16 1388 kv outrunner
Both these motors have been used extensively with my 54, never a problem before. I am hugely disappointed and missed a perfect flying day yesterday.
What can/should I do, I am pretty sure the 54 is less than a year old.
Help Castle!
