Please tell us a bit about your UAV interest
I flew FC helis in Hong Kong the early 2000s and got tired of crashing them. Flash forward to 2014 and I purchased a DJI Phantom. I fell in love with quadcopters, and found the Arducopter. I've built 5 of these now (including a Turnigy Tricopter) and love the system. I'm doing case studies for my new book on Arducopter, DJI (Frank Tao Wang was a Masters student at HKUST when I worked there) and the IoT

"I'm saying R=1 ... but in my case, I just experimented"
"I think you could probably go with 1-10uF caps ... I just happened to have the 100uF laying around, and I had a lot of them. "
"The servo and that solved the problem. I put 100mF caps (I only need to pass 50Hz signals) ... it's a Chinese telemetry module, so their filtering is poor to nonexistant ... my bad, but I solved it."
"There is a simple solution which probably should be done to assure smooth operation of all servos when telemetry modules are connected -- put a 100 microF cap from the signal wire to the ground. The telemetry unit, even counting sidebands, is…"
"Here is a solution that chips away at the problem.
It seems that the servo jitter is caused by both RF noise and noise transmitted through the power rail. So I've put a Faraday cage (copper, grounded to the rail) around the telemetry radio, I cut…"

I've just finished the construction of my GoDiscover FPV foam wing from HobbyKing, with an ArduPlane controller. I ran into a serious jitter problem with my analog gimbal servos (your basic Tower Pro 9g micro servo). They are jittering all over…
