My elevator servo on my trex450 pro v2 recently became very "jittery" around mid stick. No crash before the jitters. I took the top off of the servo, removed the gears, and cleaned under the plastic guard to see if that would help. It did not. I then removed the bottom and am trying to de-solder the three studs (see above the toothpick in the picture) so I can clean the brush and underside. I can not get the solder off the studs. I have used desolder wick and that did not help. Anyone have any suggestions? Thanks
