::) What's the problem/draw back with using a RC OS engine that you already have instead of buying a CL version?
Thanks, Terry

Hi Terry,
The OS LA, FP, "35 S",etc., are the same except for the carb/venturi. A lot of people just wire the carb open and use the R/C engine. Tming wasn't changed for either one.

Hi Terry
The CL and RC versions are NOT all the same, some of the CL versions have 2 port sleeves and some of the RC version do not.
Also you will want to put the NVA in the front and at least you will get a venturie you can use buying a CL version over a RC version.
I NEVER liked the way they run wired open, unless they were run in a 2 cycle mode, that being said If you care to you can you can covert your engine over to a CL version

Sorry, Randy, I was not aware of that (2 port vis a vis 3 port)! Is this with all the OS engines?? The 35 S, FPS and LAs I have had apart did not exhibit this, maybe I was just "lucky" ( ??? )
Thanks

::) Also with that being said, Do the OS Control line engines 4-2 cycle too?
Great site!

Terry you need to tell us which OS engines you are asking about.

Sorry, I have only seen the os-la versions. That is also what our local hobby shop stocks. So I that is what I would most likely use.
Thank you all!

Hi Terry
The OS LA s are the ones that come in 2 and 3 port versions, So if you buy a motor, I would suggest buying the Cl Version To Start with

Hi Randy, from what I can see on the OS Max website and looking at some of my engines, the piston and sleeve part numbers are the same for either the C/L or RC versions of both the LA .40 and .46.
Here are the website pages for the LA .46 in both versions
C/L version http://www.gpmd.com/cgi-bin/wgpprt100p?&I=OSMG1446
RC Version http://www.gpmd.com/cgi-bin/wgpprt100p?&I=OSMG0046
I understand that the earlier versions of these engines were coming through with both configurations but they have settled on the two port sleeves.
So if it's a new engine either should be OK. If it's an ebay special... all bets are off.

Hi Dick
Maybe so maybe no. I have 2 "new" OS 40 LAs here Rc versions that have 3 port sleeves
Depends on when and were they where bought I would imagine. OS runs 1000s of these at one time, and you can possibly get an engine that has parts that were ran several years ago.
I have also had customers ship me OS LAs that are new in box with the old 3 port sleeve.
So I would still suggest if anyone is buying one to get a CL version, At least you will have a venturie that is usable.

:P Do the Os engine 4-2 cycle like a Fox engine?
Thanks for looking!

Hi Terry
Yes many people run them in a 4-2 , however they do not sound like a FOX 35.
