Hi I found a post from Paul Newell 2007 I think. I built the Microtrol system when it first came out with parts from chap in Sunderland. It did work with a little help from an electronics engineer/scope etc. It was used only once resulting in a crass which quite put me off! I still have the set but it is now not working - no RF output from the TX. Anybody with any suggestions on the fault? Dave
