Mikrokopter Mikrokopter throttle, full range not available

[Bartman]

Hello everyone,

I'm trying to work out a problem with a Mikokopter FC2.1 (with MK BL 2.0's). The helicopter recognizes zero throttle as it is allowing me to arm the motors but the throttle channel in MK tool doesn't show the throttle position moving until it is at mid position. So the FC must be recognizing the zero position because it's allowing the throttles to arm but I can't get any throttle response because the channel 1 slider isn't showing any response in MKtool.

When I changed the throttle channel to 3, I was able to arm the motors and the FC responded normally. Using the same radio for a NAZA flight controller, I was able to see full throttle range in the NAZA Assistant so I know the channel is functioning within the transmitter.

Is there any way to calibrate a Mikrokopter throttle channel?

I also tried using subtrims and travel adjustment to make the throttle work correctly but it was of no help.

Any advice or ideas would be appreciated. Thanks.

Bart

Bart did you try the hidden menu stick calibration on the MX-20? Had something similar happen and the sticks were out of calibration.

Gary,

It's a JR 9503. Where is the hidden stick calibration menu? In MKtool or in the MX-20 radio menus?

Bart the stick calibration is in the MX-20. Not familiar with the JR's but maybe they have something similar. Basically you go through a full series of stick deflections and the MX-20 'calibrates' to those full positions.

Gary,

I don't think the JR has that feature. I've got to check another MK FC to see if it behaves differently and then maybe search the Wiki (joy!) for more info.

Thanks,
Bart
