בעיה עם HEAD TRACKER + CPPM

סליחה שזה באנגלית העתקתי את זה מ RC GROUPS
חשבתי שאולי מישהו כאן מכיר ויכול לעזור לי בבעיה .

Hi i am using Dragon link + dragon OSD systems when they are connected throw CPPM and working fine . lately i added Head Tracking Module using turnigy 180 for pen and HXT900 for TILT. they are connected to the dragon link directly from channels 5-6 (my osd control channel is 7) . now the issue is that when i am moving the pen servo (turnigy 180) my tilt servo is getting interfirence and jumping up and down all the time when the pen servo is moving. as for now i tryed to move them both throw the aux sticks at my TX and also from the trainer port and with the Dominator Head Tracked.

Any one know what is the issue might be?

Many thanks
