I hope this isn't common knowledge but I thought I would share with my fellow beginners.
If you ever get a tm1000 telemetry module from spektrum be carefull of where you route the antenna. Make sure it isn't near your servo leads.
I spent two days trying to rectify servo jitter on my digital servos. I cleand the pots tested wiring but couldn't truly get rid of it. (minor and mostly when centering). By accident I discovered when I pulled the tm1000 out ALL the jitter was gone.
I so I put the tm1000 telemetry module in my hand and fired it up. If I put antena near any servo lead, Jitter (didn't matter what lead). Pulled it away and it stopped.
Hope this helps someone from pulling their hair out
