<p><font size=3 face=Arial><span style='font-size:12.0pt;font-family:Arial'>My
time with the OS 1.40RX goes back to 1997/8 when I bought four of them and a
tuned pipe from a small English hobby shop, on one of my trips to the UK.
Although I don't own the motors anymore I know where they are. :-)
The <st1:country-region w:st="on"><st1:place w:st="on">UK</st1:place></st1:country-region>
customs had a fit when they saw the pipe on their x-ray machine... Just made
the plane in time...</span></font><o:p></o:p></p>
<p><font size=3 face=Arial><span style='font-size:12.0pt;font-family:Arial'>The
first modification was a new carb-jet that OS provided FOC to cure a mid-range
gurgling problem. Back then, the motor was a novelty and not taken
seriously, even though it pulled my old Hydeout vertically out-a-sight.
Things went quiet for a while and around the year 2000 there was an upsurge of
interest. The EFI caught a lot of attention and then the experimenters started
working on their 2-cycles of all types. The second modification was to fit
stainless steel bearings :-)</span></font><o:p></o:p></p>
<p><font size=3 face=Arial><span style='font-size:12.0pt;font-family:Arial'>The
price of the OS 1.40 EFI made us look at the RX again. Dave Shadel came
out with a piston and liner. Fuel was modified to meet the spec's that OS had
always listed. Coolpower was always around 15/17-18 and often proved to be the
best fuel for the average pattern OS 2-c pundit. The OS 1.40 RX had a different
shaft and carb by then. The new carb had a bigger throat and the shaft had a
narrower mouth. Never got to try an old shaft with a new model carb. Did cut a
1.40 two plug head that was never tested. Found out that one OS "F"
did the job with less plug-fuss.</span></font><o:p></o:p></p>
<p><font size=3 face=Arial><span style='font-size:12.0pt;font-family:Arial'>The
Shadel liner is not a must but does give more power. I like it because it is an
aftermarket add-on that anyone could fit. Another aftermarket is the OS mixture
carb. I first heard of this from Jeff Carrish. I then got to fly one on
Dixie-Chicks-Earl's Temptation. The Webra MC testing got me interested and then
the flight-experience convinced me that this carb (Approx. $79) makes a big
difference. You have five points on the carb and seven on a JR 10X. You can
adjust the carb to perfectly match the behavior of almost any pipe. With the OS
Hatori and this carb on a 1.40RX it was just like flying the 1.40 EFI. ( This
motor BTW still had the std liner etc.)</span></font><o:p></o:p></p>
<p><font size=3 face=Arial><span style='font-size:12.0pt;font-family:Arial'>I
was so impressed with the tunability of this carb that I am fitting one to my
1.60 as soon as it arrives in the mail - checking for it every day...!!</span></font><o:p></o:p></p>
<p><font size=3 face=Arial><span style='font-size:12.0pt;font-family:Arial'>As
much as I like to only do easy after market mods, I did break down with the OS
1,60. The 1.40RX pump was so good that I grafted one to my motor and ran it
last season. The 1.60 Carb worked just fine and I am told that the 1.40 RX
carb works even better, at least in <st1:country-region w:st="on">Norway</st1:country-region>
or <st1:country-region w:st="on"><st1:place w:st="on">Sweden</st1:place></st1:country-region>?
(They all have 15 mm openings in the crankcase). An OS 1.60 FX w/pump
and an OS mix carb should be pure fun to play with and of course, fly!</span></font><o:p></o:p></p>
<p><font size=3 face=Arial><span style='font-size:12.0pt;font-family:Arial'>I
still hope that OS will come out with a rear exhaust 1.60, (or more),
w/pump.</span></font> <o:p></o:p></p>

winter over yet?</span></font> <o:p></o:p></p>
