Default R/C to C/L motor conversion??


I have several OS .40 LA R/C motors & am wondering if i can swap out the R/C carb for a venturi to use in C/L work? These motors have the remote needle valve on the back plate. OS no longer makes the .40 LA motor & am wondering if i could even get a venturi for these? I have several C/L models i want to build this winter & would like to use these motors on them, .....Gene[]

The LA .40, .46, FP .35, and FP .40 all have the same size opening in the case for a carb/venturi. OS is still selling the LA .46/S, so one of those venturis should be available and work OK.

The remote needle is kind of a PITA. They often leak air. I quickly tossed it on my LA .46 and replaced it with a ST locking collet type normal C/L needle valve. I think I had to drill the case/venturi insert a tad to get it to fit.

The stock OS mufflers are a heavy brick and prone to falling apart and you lose the back half. Fortunately, a Fox Stunt .35 muffler fits the LA .40/.46 and FP .35/.40 just fine, weighs less, and is more easily tuned in terms of restriction via drilling out.

You can just wire open the RC carb too. That works fine, it just weighs a tad more.

Quick simple and only takes seconds to replace the small band

You can also take advatage of that carb. Find a cheap (even park flyer range) 2.4 radio transmitter and use it for throttle control. Great for trainning as you can adjust the speed and land when you want.
Here is one that is way more than needed.

I think you could get by for almost halve as much $ but It take a litle hunting for 1
