O.K. However, the vertical position of the engine is not
important.
We can lower it below the upper cowl. Many different auto engines
have been put on the 701. But my favorite is the Harley. The LSA
world is vibrant and fun compared with larger, faster
experimentals. Jerry
That ought to shake your airplane apart :)

Yep. That is the problem. However, it looks cool and sounds
wonderful. The builder has grounded himself because the
vibration is
scary. Jerry
Jerry,
Probably for two reasons, ONE it probably needs balancing. I
balanced my
1200 cc and it ran beautifully without rubber engine mounts.
TWO, I don't suppose there is a dampener on the engine to soak up
the torque
pulses.
Paul, what's the torque reversals for a 2 cylinder - worse than a 4
cylinder?

Well the hog motor is strange. There is only on crank journal on the
shaft. It is sort of like a big one cylinder engine.
Probably fires the same as a one rotor. Once per rev.

Here are the 3D's. I lowered the engine. How much clearance will
you have
for the prop with a 3 inch lower thrust line?

That would be six inches with a 68" prop. Jerry
That ought to do it.

This is the lightest and cleanest engine mount ever designed for the
701. I would like to build the drive but there are two one the
market and I have plenty of time. What do you think of just
bolting the single rotor together without the eccentric or rotors for
mocking up purposes. I could build the engine mount, intake and
exhaust? I am depending on others to come up with the cut down
eccentric and the aluminum side plates in the near future. Do you
think this is realistic? Jerry
Sure it weighs less too.
