Throttle Trim
•Throttle neutral adjustments can be made by moving the throttle trim to the left or the right.

When using a electronic speed control, please set the throttle trim to neutral and make adjustments to the speed control. On a gas powered
model, set the trim to the point where carburetor is fully closed in accordance with the engine instruction manual.

and inspect your throttle linkage.
