<DIV><FONT face=Arial size=2>Center and "snubber bolt" size is 10-32 stainless
steel with aluminum nylon lock nuts and aluminum washers. The engine hold
down bolts are 6-32 steel with steel washers. The Rotomount in my EMC complete
with all hardware, snubber block, lightly coated with epoxy and painted black
was 2.6 ounces. My clayton foster nose ring with 2 4-40 aluminum
bolts and blind nuts and lite ply mounting ring with lightening holes was just
under an ounce. So the total engine mounting assembly including everything
except firewall was 3.5 ounces. Firewall is 1/8" lite ply. The mount is
constructed of maple beams tapered and pared down to hold the engine and the
beams are glued to a 3/8'' plywood disc that has been lightened. The snubber and
center bolts are surrounded by silicone tubing of 2 different outside
diameters.</FONT></DIV>
<DIV><FONT face=Arial size=2>When I was building my EMC I was looking at every
piece that went into it to ensure I would make the 11lb weight limit, plane
ready to fly came out at 4861 grams or 10 lbs 11 oz. As a side note, I saved 24
grams in hardware but using either aluminum or stainless steel throughout the
plane. One good thing about the rotomount is you don't get the slight side to
side movement at the back of the engine that you do with the Hyde mount. Yeah,
it takes some work and we seem to be in an era of buy and fly but with
a little time and creativity, it can be done. Bob Pastorello has an excellent
soft mount also. </FONT></DIV>

<DIV><BR></DIV>Ed, <BR>I'm curious as to what size center bolt you employ in
your roto-mounts? I tried making one and the weight came out at a little over
5 ounces. I abandoned the idea in favor of a simplified version of a Hyde that
I can make at 3&1/2 oz. With the exception of the Sig rails mine costs
about 25 cents. <BR>Georgie

Rotomount and Clayton Foster nose ring get my vote. The Rotomount can be
made very light and it's adjustable for firmness and thrust angle. I've had
5 planes with it without any problems. Works on the same principle as the
Hyde mount in that it allows the engine to rotate along the crankshaft
centerline. A side benefit is it costs less than 10 bucks to
make.</FONT></FONT><FONT face=Arial><FONT size=-1>Ed M.</FONT></FONT>
