  • 150% gain & no wag...Why???

    Why is it that i can put the gain right up from 75-80% right up to 150% with no noticable difference??? Surely the tail should be wagging more than an exited mut on speed?? It will hold regardless on full pitch climb outs. Oh it's a CSM 720 as most know anyway.

    What headspeed are you running?

      What you adjusting it on gear ch or Atv's?

          On the gear channel. As for HS??? i always run idle 2 100% flat but no idea on the actual headspeed

            Have you tried moving the ball outwards on the servo arm? This provides more mechanical gain and allows a reduction in the Tx.

                Are you sending the gain signal to the right channel?

                I had this once.

                I was adjusting the endpoints on the gear channel (5) all the way from zero to 150 and it made no difference at all. Found out eventually that I had the gyro sens function enabled on the Tx (DSX9 for me) and the gain signal was in fact going to Aux 2 channel (7) so my adjustments weren't doing diddly squat!

                  +1 Ive had this too Led me a bit of a dance for a while....

                  What length servo arm are you using ?, CSM recommend a min of 15mm from servo center to ball. Does the gyro have full use of the tail slider?

                  And as a thought, you havent changed anything with the pc interface that could limit the servo response?

                    Hey guys, I have seen this heli and the servo horn is the correct size for the tail. Logo 500 with a JR 8900G (Round disk) I'm using the same servo on my Logo 500 without issue. It's a gyro thing...
