<DIV><FONT face=Arial size=2>Lance,</FONT></DIV>
<DIV><FONT face=Arial size=2> Thanks for passing that along. FYI the ARIA
mount for an OS160 places the thrust washer 6 3/8" from the firewall too. It
looks like we've finally arrived at a "standard" of sorts. Yeah.</FONT></DIV>

Dimension - Hyde "Type C"</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>These type C's are really new (the Mk III's
anyway). I would assume Merle's dimensions have not really
changed. Here's some info I got from Merle directly that others may find
interesting. I sure did:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV>Hi Lance,<BR><BR>I don't have any pictures. The new "C" MKIII mount
(isolator) looks the same as the earlier ones. Now I am using
rectangular 1/4" x 1/2" aluminum beams oriented/attached flat on the
mount. This makes the mount now usable with 18 pattern engines,
including the OS160 which is a wide crankcase engine.<BR><BR>Each beam has 6
drilled and tapped 6-32 holes - permitting a wide application range.
Beams positioned flat are even stronger. Overall length from firewall to
thrust washer is 6 3/8" for all YS, 3M, WEB, OS140, OS160, and OS120-200 4
strokes. Use of different beam bolt patterns even permits 6 1/4" FW to
TW for many engines!!<BR><BR>The "AR"(A)s (2 engine lug holes attachment) are
being discontinued and being replaced with all 4 engine lug attachment
aluminum beams. The newer mounts, that replace them, are being rated by
"CDR" (current drain reduction). The "CDR" range is from 60-95%, and the
mounts will be identified as "AR 60", "AR 70", "AR 80", "AR 85", "AR 90", and
"AR 95", plus a very light weight MICRO series, that are "MR 80", "MR 85", "MR
90", "MR 95".<BR><BR>The highest CDR numbers are the softest mounts and
require more airframe clearance for idle movement, plus softer mounts requires
exhaust attachment methods as we have discussed in the past, or a method for
the exhaust system to endure the "ride" or additional movement - overall
benefits of the very soft mounts are to the major high value airborne
equipment - such as servos, pots, gears, linkage, including entire
airframe.<BR><BR>All are for 4 engine lug hole attachment and position the
most popular engines at 6 3/8" or 6 1/4" from firewall to thrust washer.
<BR><BR>The "AR 80" is highly recommended by Mike Hester for the "beastie
DZs".<BR><BR>I will continue the firmer Type "C" MKIIIs.<BR><BR>The CDR rating
is an average for engines from 1.20 to 2.0 cuin. - the rating is approximate
for a 160 size engine. The aluminum beam mounts will no longer be engine
specific - except for those that incorporate the nose ring - the ARI series
must be set up for a specific engine due to varying front housing diameters
and etc..<BR><BR>I'm sure this will be confusing for a while - but with
consistent overall length and wide engine applications there will actually be
considerably fewer mounts to chose from - approximately 10 if all the
CDRs are in the mix - vs 25 to 30 - Central carries the "AR 80", and may
include the "AR 60"s and "AR 70"s. Also I have modified the firewall
attachment bolt pattern to permit use of either 3 or 4 attachment screws - the
new bolt pattern permitts the selection of either a "triangle" or "rectangle"
pattern - making the mounts interchange with other brands - plus permitting
the use with many engines makes the mounts fairly universal. The pattern
guys like to interchange engines, they can now also interchange some
mounts..<BR><BR>Best,<BR><BR>Merle<BR></DIV>
