have both your throttle and brake endpoints (called EPA or ATV on your radio) on the throttle channel set

to between 100 to 120%. If you have a Futaba-made transmitter, make sure to have the throttle channel

set to the reversed position. See Castle ESC/Radio Calibration on page 10.

Problem: My ESC calibrates for the full throttle and full brake positions but won’t calibrate to the

neutral throttle position (yellow LED keeps flashing with single beeps).

Solution: Try moving the throttle trim one way, then the other. If your transmitter has a 50/50 and 70/30

setting for the throttle, set it for 50/50 and retry calibration. If you have changed the throttle dead band to

a narrower band using Castle Link, you may want to try going back to the “normal” setting.

Problem: My vehicle acts like it has “turbo lag” (poor acceleration/punch for the first few feet or

yards, and then it “kicks in”).

Solution: Make sure you’re using high quality batteries and a battery connector capable of high amp flow

(40-100 amps). Ensure connector is properly sized for your application. This behavior is very typical of a

battery pack that is having difficulty providing the power your system requires for top performance. Refer
