Motors won't stop

Hi all,
I've got the following problem.
I've been building a MWC (with BMA020 in X configuration) and I'm controlling it with a Futaba FC18 (first version, so "rather old").
When I use the menu 13MIX-TYPE(AC2) on my TX, everything works well. :D
I can arm and disarm my motors without any problem. (All channels are set to 110%)
But… with the TX in AC mode I can’t get the copter to a stable altitude. :(
One “down-click” on the throttle and copter descends and one “click higher” the copter ascends too much.
So, I tried the 13MIX-TYPE(HR3) mode on my TX to get more control on the throttle curve.
Everything is working nice so far, I can arm the motors, the throttle is better, but…….I can’t DISARM the motors. I have to pull the battery plug to shut them off.

Please can anybody give me some advice, even better the solution. :idea:

Test this.
In config

Code: Select all

/* this is the value for the ESCs when they are not armed
   in some cases, this value must be lowered down to 900 for some specific ESCs */
#define MINCOMMAND 1000

Do your Yaw rc-value reach 1100 - 1900 in gui?
1100 is the limit to disarm.

You can also use a arm switch set in the gui.

Hi Patrik,
You gave me some good advice. :D
In the AC2 mode the values for the yaw were Left 1054 Right 1973. Arm/disarm OK
In the HR3 mode the values for the yaw were Left 1590 Right 1865. So NO arm/disarm.

I did some experimenting in the submenu's of the HR3 mode and came out to the next values.
YAW Left 2000 and YAW right 995, so......... arming OK and disarming OK.
Still have to figure out what exactly I'm doing, cause I don't (yet) :oops: But I will.

Thanks for your advise,
Greetz from Holland
