RE: Eletronic engine syncronizer - no joke
GPF:
With the magnet and sensor in line the signal becomes erratic when the separation gets over ¼ inch, at 3/8 inch it almost never triggers. With the Genesys magnets not only ¼ inch or more away but off axis as well, you’ll probably be OK. If you can put the TwinSync magnet and sensor further off the axis of the Genesys magnet ring I’d do it – the more margin the les likely to have any interference.
In any case, you should do some careful testing to be certain the space is sufficient.
Engine? How about a nine cylinder genuine radial, 7 1/16 inch diameter, and swing a 20x8 prop? That’s the Technopower 9B engine. Call them at (714) 546-6194 and check on availability.
