HI can anyone help me please i have bought a ripmax 25a xtra brushless speed controller and can`t get the throttle to work lower than half stick. It stops when it moves lower than half way and only picks back up when it is back over half way. I have a futaba 6exa and have messed with the EPA and TRIM settings and wiped the model memory and still have the same problem. Has any one else had this happen to them as any help would be great.

Where is the trim?

I'Ve just re-read you post - lower? Since you have a Futaba you must reverse the throttle action. Pull the lever to bottom, reverse the servo function, push up and it should work.

Thanks for the info cheers Paul.
