> Jerry,
> Send the S-beam with the Barry Mounts installed. Also, send me your address so I can mail a
check for $??? This is for an acro biplane with "G" limits of (+) (-) 6. I remember you did some
"scientific" tests with a block of wood and a truck tire. Are you comfortable the S-beam will
handle these loads?

>>> Hi Jerry,

>> Randy, I do have S-beams available. Do you want just the beam? Or do you want the Barry
Mounts installed? This involves no more than welding a Barry Control snubbing washer to a 3 inch
long bushing. If you don't know what I am talking about, I can send a picture. Jerry

Randy, there is no doubt about the adequacy of the S-beam to deal
with any flight imposed loads including hard landings. I will have
to order a set of Barry Control bushings and snubbing washers which I
will do on Monday. Once they are received I can quickly assemble a
beam and send it to you. The beam will come ready to install. Are
you aware that the RX-8 oil pan will require modification to fit the
S-beam? Also, are you aware that the S-beam only controls the front
of the engine. The rear engine load is controlled by a strut that
goes to a hard point, usually on the firewall. There are drawings
and photos of how different builders handled this. I am sure you are
aware that Paul L. will design a bullet proof engine mount for you
using the s-beam. His drawings are the way to go. The engine should
be installed far enough forward to have adequate room between the
engine and firewall. This will have very little effect on the c.g.
if the plane was originally designed for the 0-320. If I was
designed for the 0-360 than you can move the engine forward even
more. Fine tune the cg later with battery placement.
The price is $100.00 plus shipping.
Regards, Jerry
Jerry, how long are your beams? Randy has a narrow
fuse as it is single place bi plane. Therefore I cut the beam
down to 22 inches. BTW that also makes it much stronger
than the 30 inch beams.
