Will try and get a pic Dave but the electronics unit is the rx and the arduino onto a circuit board with the mosfet driven relays. The arduino is fine but the rx is sliding off its pins. So its mainly a cable tie or glue gun kind of job.
Yeah the speedos are the 85a's. I did some research and knew that they should do fine. Had an interesting chat with Gary from team saint and it might be a consideration to create a heavy with 4 E30s and 4 85a speedos. I do however have a wotty just lying about so should plan something around that.
And finally cheers Chris
