Reversing servo at APM

Hello all,

I just finished building up a new bixler and I hope to get it in the air this weekend. It’s driven by a APM 2.8 with Arduplane 3.4.0 (displayed at Apmplanner2 at start.)

My Problem: The servos turn wrong in FBWA and I cannot find parameter SERVO1_REV in full parameter list as I read in plane documentation. If I try to change at MissionPlanner (param is displayd there), the plane answers an error.

Has that param a new name? Can’t wait to fly…
