Guys,
One of my Align ESC's (the one that came with the SE V1) has much less power than the other one. I put it in my other 450SE to see if it was the motor or something else but its the same. I resoldered all the connections and they're fine. Now there is no increase in headspeed when I switch into idle up. I thought it might be in gov mode but checked the programming and its not. For quite awhile it was just less powerful but still ok. Now it seems to be less. I just went out to fly and had trouble completing stationary flips. I've tried it on 3 different motors so that's not it. Ideas?

I had the same problem with a Castle Creation 35a controller. I replaced the bullet connectors going to the motor, one looked like a cold solder joint, and that fixed it. If you already tried that and reprogrammed it, I'm guessing it might have just gone bad, it's strange that it still works some though.
