Yes, the tach thing will be a problem.
Maybe a coil wrapped around the plug wire would generate enough volta to trigger the tach in the TM1000 rpm module, couldn' hurt to try?
Next, is the prop thing.
I didn't realize the pitch is different on a large prop.
Seems like a 12" pitch would still give about the same speed as a smaller 12" pitch prop,
just a lighter load on the engine.
I think I'll break it in with the prop I have, just watch the rpm to keep it low enough.
Don't think it's the voltage that has anything to do with the TM1000 not reading the RPM. It's an incompatibility with the output of the RCEXL tach and the RPM input adaptor. Some have tried tapping straight into the hal sensor with luck.
Also the pitch isn't "different" on a large prop. It's just whatever gives the engine the proper load, and you can adust slightly with pitch and diameter to better suit the specific application.
