With all 6 Aux outs used for BLHeli32. Where can I connect a servo?

Hi, Since the aux outputs on a PixHawk 2.4.8 are the only outputs that can be used for BLHeli 32, I have used all of them for my hexacopter. I wish to control my landing gear servos and tried to run them through the main 1-8 outs without success.
I have set SERVO4 FUNCTION to 29. Powered the rail, set all the LGR_ parameters, and set CH7_Opt to landing gear.
What am I missing?

Hi, maybe you’re wrong. I used output 1-8 for other things like for the landing gear and everything works perfectly, of course you have to indicate the function, otherwise the action doesn’t happen
