not I will be flying with the 170 or my O.S. But I just might drop the 170

<DIV><FONT size=2> I talked with Michael Rudinsky from
Boca Bearing while in Toledo. He did measure the bearings in my 3M 170
engine. The frt. bearing is the same as the frt. bearing for the O.S.
140 RX. Michael told me the rear bearing is a standard size, but they
do not stock it. Michael told me that he would order some and call me
when they came in. I have not heard from him yet. I will call
him tomorrow and let the discussion page know what he came up with. In
Toledo he also told me he would be able to offer the bearing in the ceramic
version for those that are interested.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2> On the installation of the 3M 170
engine question. I installed my engine on a Hyde ARI (A) mount for an
O.S. 140 RX. It was a direct bolt in deal. The exhaust clears
the mount with now problem. The 3M engines use an o-ring
manifold that the header attaches to, just like the O.S. You can
use an O.S., Harori, or 3M header on the 3M manifold, and will all
clear the Hyde mount. The only difference between the 170 and the
O.S. 140 dimensionally, is the 170s cylinder is slightly taller and larger
in diameter, otherwise it is all the same i.e. exhaust location, throttle
hook up, and fuel line hook up. The needle valve is slightly higher on
the O.S. than the 170, but on the 170 you can change the mounting angle of
the needle valve if needed to line up with an existing hole in your fuse if
swapping from a O.S. 140.</FONT></DIV>

<DIV>I can offer an answer for #1 only . . . .. . .</DIV>
<DIV> </DIV>
<DIV>Mike Darr had his 3M 170 at the Toledo show, the Boca person at the
show measured the bearings so they could offer replacements. I would call
Boca to see if they are available or when they may be
available.<BR><BR><B><I>GW <<A

<DIV><FONT face=Arial size=2>For those in the know regarding the 3M
170::</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1: I notice the rear bearing is a double
back ball bearing, I do not know what this truly means, but will Boca or
the US based 3M retailers have the replacement bearings available?
Any other substitutes? Don't want to be needing a bearing in the middle
of the season and be waiting for a bearing from Italy!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>2. Same question as above but regarding
rings? Do the retailers like BuyRC, PlanesPlus, AeroSlave, etc, have
replacements in stock, or plans to? Again, I do not want
to be without use of an engine waiting on a ring or bearing from
Italy!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>3. Will the 170 be a drop in replacement
for the OS 140? I have heard the bolt patterns are the same, but what
about the position of the nose ring, exhaust,etc? Completely
interchangeable with no refitting needed?</FONT></DIV>
