Tracy,
Any chance we might see you at Oshkosh with your new RV8?

The heavier flywheel should he= lp=20 but there is more to it than that.

I was contracted to provide ECUs= for=20 the Itec Maverick, a powered parachute / car.  
I recently learne= d a=20 lot about idle requirements on engines without a propeller load when I vis= ited=20 their factory to work out tuning for the engine without a prop load (in gr= ound=20 mode).
  Been working on a new idle control strategy for the EC2/= 3=20 that I think will greatly improve the minimum idle speed and smoothness of= the=20 engine at low RPM.   Because it wasn't really needed in the past= , I=20 did not have a separate idle strategy in the EC3.  I'll report= =20 more when it's all worked out.

BTW, this is the first flying car I'= ve=20 seen that kicks ass on the ground!
