I used P/P rudder and elevator for scale reasons on many small electric WWI models and thought I had it mastered, however on my 50cc Extra I find p/p to be a whole different story.

I noticed the rudder servo was twitching, (JR DS8411). Tapping the servo or bumping the rudder stick got it to stop for a while.but it soon started again. I managed to break a cable, so I will be setting it up all over again. Is the digital servo a poor choice for rudder p/p or was it just my poor setup of the cables which was causing the servo twitch?
