Paul,

Are the Barry mounts the same units as those used on tracitional aircraftÂ
motor mounts?

Joe Berki

No but they are made by the same company out of the same material and
they are
one tenth the cost of aircraft mounts. They are used on the Questair
Venture as well as a dozen or so rotary powered aircraft.Â

Hi All,
Which of the Barry mounts are being used with our rotary engines? Mine
is a 20B, so I'll need a little stronger one than for a 13B. Does anyone
know where the specs for the Barry mounts are listed? I cant seem to
find any...just part numbers.
Thanks,
John Bell

We use the same 22002 part numbers for the 3 rotor but a higher
load rating. They come in many load ratings up to 630 pounds each.
Here are the specs. McMaster Carr sells these under different part numbers.

"Versa-Mount Two-Piece Vibration-Damping Mounts"
130/50 (35A), 240/90 (55A), 380/165 (65A), 630/280 (75A) 6309K3    5.95
You want the  380/165 pound mount for the 3 rotor when using two for the
Schertz beam. The reason is there is about 684 foot pounds of torque
applied to the motor mounts from a 3 rotor.

If you don't use the wide mount Schertz beam design you are on your
own about loads. Contact Jerry@jerryhey.com for Schertz beams.

Here are some 3D's of  a 3 rotor RV10 installation.
The same idea will work on your Velocity. Send me a sketch
of the firewall hard points and I will do something similar for the
velocity.
