Hi,

Are the new EIS prop hubs interchangeable with the old? Also, are the prop bolts on the EIS 50, 64 and 86T the same size as the magneto versions?

Thanks.

The EIS engines are the same engines as the CI engines, they just have a different ignition system. The flywheels are different, though. Everything else would be the same.

Thanks for the reply. I noticed the 50/64 EI conversion kit comes with a new prophub, so I was wondering if I could reuse the old prophub on the smaller EI flywheel.

Also, I have a Fuji 86T and would like to know if I can turn the cylinders 180deg, such that the carb in on top of the engine and the muffler still pointing downward. I should just have to turn the pistons 180deg as well, so the ring gap is on the same spot on the cylinders, correct? I would like to use this engine in a 33% Su-31 and would prefer not to have the carb between two hot mufflers.

Volfy,

We're sorry, but the cylinders cannot be rotated to put the exhausts down and the carb up. Rotating the cylinders would cause misalignment of the bypass ports inside, and the gaskets wouldn't seal properly.

Thanks Bill for the info. Oh well, it will work fine as is.
