I just received the new plate mount from Jeff this morning, and it is very
impressive. You have to hold it in your hands to really appreciate its
lightness compared to the original  adapter plate.

Add in the fact that it is also the engine mount, and will accept whatever
starter you have, wow! If you are going with a TC PSRU, this is the way to
go. Truly amazing.

Those "cups", are they replacements for the stock engine mounts?

Yes. Most people don't use the stock mounts. They are very heavy and the 900
foot pound torque from the 3 rotor prop must be reacted by the mounts so
putting them on the PSRU adapter plate mount is the best place.

We use the low cost (under $10) Barry Controls 2200 series industrial rubber
bushings. This is the same mount used in the TIO 550 Questair Venture.
Lycoming rubber bushings are $100 each.

Paul, what's the best way to order the Barry mounts? I'm a little confused
by the Barry controls website.
We need the 22002 model yes? Best place to order from?

Contact local bearing supply houses.
Looks like the closest one to you is in Ohio.

Also McMaster Carr sells them. Choose the part # 6309K3
the 240/90 55A Durometer is about right but I would buy a couple
on both sides of that and see which ones give you the best vibration
isolation.

Not that vibration is any real consideration as Perry Mick
has been flying his long EZ for years with the rotary engine solidly bolted in  :)


The left side (pilot side) gets most of the load so put the harder
one on that side.
