<P><SPAN lang=en-us><FONT face=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 UK customs had a fit when they saw the pipe on their x-ray machine... Just made the plane in time...</FONT></SPAN></P>
<P><SPAN lang=en-us><FONT face=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 :-)</FONT></SPAN></P>
<P><SPAN lang=en-us><FONT face=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.</FONT></SPAN></P>
<P><SPAN lang=en-us><FONT face=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.)</FONT></SPAN></P>
<P><SPAN lang=en-us><FONT face=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...!!</FONT></SPAN></P>
<P><SPAN lang=en-us><FONT face=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 Norway or Sweden? (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!</FONT></SPAN></P>
<P><SPAN lang=en-us><FONT face=Arial>I still hope that OS will come out with a rear exhaust 1.60, (or more), w/pump.</FONT></SPAN> </P>
