thanks guys,
engine revs , I can set max revs on the signal reversing cable ( small pot on board )
Im more focused on the rotation jerkiness ( if that's a word ), I will try joes suggestions on the radio and see how we go.
if I cant get any joy out of that next will be an esc, the more play time with the radio the more confidant I am becoming at changing things up, also learnt write things down before I change too much LOL.
thanks for the help

cheers andy
