flex plate while we are running with flex plate only.

Paul, almost any engine will rev to destruction if you open the throttle
with no load on the engine whether it has a flywheel, or not. The trick is
not to leave the throttle open when you start them up. I ran my turbo 20B
with a light weight aluminum flywheel (about 8-10 lbs, I think) and the
Ross gbox, but without the prop, for several hours. It sure would rev fast,
but it's really no different than stepping on the gas of a manual tranny
(in neutral) car.

There is a big difference in flywheel weight and rotational inertia.
The flex plate normally has a heavy torque converter bolted to it
and the rotary manual transmission flywheel and clutch 
plate cover is 35 to 50 pounds. The rotary engine angular acceleration IS
much much faster than just about any engine.

This is not to be taken lightly. It could be fatal under the wrong 
circumstances. PLEASE be careful!
