You might be able to fix the issue yourself by using this procedure:

Using a radio that will correctly calibrate the MMM:

1. connect a servo to the throttle channel and power the RX with a battery
2. note the servo positions at max throttle, neutral, and max brake

Then, using the KO Propo radio

1. connect a servo to the throttle channel and power the RX with a battery
2. adjust the end points so that the servo positions match the other setup

Thanx!
