Thanks I am on holiday from this weekend for 2 weeks I will contact you when I return.The ignition system is home made, based upon information cleaned on this site. I can send you a board and instructions, not hard to assemble. A few have commented on track widths etc and suggested improvements. I have tested one for many hours on a test rig and it is still fine, in fact it is the one running the engine in the video. Besides I have several boards in stock as there was a minimum order.
If you would like one, let me know where you are and I will send one.
