3M Mintor 170 questions

Mon May 5 10:20:31 AKDT 2003

Hi Eric,

I've had the Bolly 480, 590, and 565.  The 565 worked the best on the
ST2300.  However, each of these pipes was easily outperformed by the ES.
The 3M carbon pipe has the first baffle in the same location as the ES
2-cycle pipe I have and it looks very similar in overall dimensions.  If I
remember correctly, the first baffles of all the Bolly pipes were a lot
closer to the neck opening than the ES or 3M pipes.  The 3M carbon pipe has
an AL neck insert, and its note is similar to an Asano pipe I've heard run
on Donny Wright's OS RX.  The Greve pipe has a longer first baffle
dimension, so you'll need to run a shorter header length to get the same
tuning as the ES/OS type of pipes.  With the 17 x 13, you'll need all the
power your can muster mister!

I noted a 2" difference in the 1st baffle position in the Bolly pipe to the
OS and OS clones. Do you have tuning distances for the 17 x 13 APC and the
Bolly pipe, by any chance??

Regards,

Eric.

I currently have spare bearings/pistons/sleeves/O-rings/cyl-heads for the
3M140 and will be stocking the same for the 3M170. So, getting spare parts
should not be a problem.

For those in the know regarding the 3M 170::

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!

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!

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?

Many Thanks

GW
