Problem with altitude_wait command

Hello,
I’m new to this forum, but I’ve been messing around with the px4 for a few months now. Thank you in advance for your help.

Recently for a project I’ve been trying to use the altitude_wait command for balloon launches. The command gives 3 parameters: a target altitude to wait for, a downwards velocity in case of early balloon popping, and a time interval for how often to wiggle the servos to keep them from freezing up. I have had no problems in testing with the first two parameters, however, the servo wiggle command had given me some trouble.

Basically, no matter what the “wiggle time” parameter is set to, the autopilot continuously wiggles servo 1 only. I’ve tried many different settings, but no matter what I just get a constant wiggling of servo 1. This is a flying wing design, so there are only two servos, but the second one won’t wiggle and the first one won’t stop wiggling no matter what the interval is set to.

Does anyone have any experience with the altitude_wait command?

Thank you again,
