M51, what material is the 3W sensor made from and have you tried the twin sync yet with this setup? As one of the oringinal beta testers for the Zenoah engines, I had no luck using metal bracket standoffs to hold the twin sync hall sensors on the G-26's. I had my magnets in the spinner backplates. The hall sensors were JB welded to the brackets , but appeared to produce inconsistant sensor pulses to the twin sync. I believe it was too close to a ground source, and remember, JB Weld conducts electicity. I wish I could remember the exact symtoms incurred using the metal brackets, but when I switched to thick plastic brackets, the twin sync worked fine. If you only have 1 North pole magnet on that 3W crank, and the sensor mount is made from non-conductive material, it should work fine. Let us know. Thats a nice clean setup and that technique may also work with the Revolution GT-26. Rick Simmons
