Dennis, I don't have the CL model, but I have a 40MK III that I've used for RC.  It's so beautiful, and runs so good that I've put it away to save it, as it is, apparently, one of the last that are English built.  You might check out the "Just Engines" site.  They are the distributor for Irvines, and although they're in England, they're geared up to ship to the US.  They are also the folks to talk with, through email, about your questions.  I got some good advice on how to convert the MK III to CL, if I ever want to.   Glen

Having been a fan of Irvine motors for a lot of years I have a fairly good stash of them including the Mills replicas. As to the Red case models  besides the 2 C/L 36's I also have 2/40's 1 46/ 2/53 1/150 1/61 2/25's. I also have a lot of the previous series including 4/40 diesels 2/20 diesels 1/20 glow 1/120 1/150 1/72 3/40  1/46
As to the Mk 1's more of the same but 2/30's also. Most of them are NIB as I''m not particularly hard on the motors that I run. Controlline is harder on motors then R/C
What can I say but for years I was a voracious accumulator. Thankfully I have slowed down as I can't find too much more room for 'stuff'
Oh and like all hoarders I hate to part with anything.

I have several of the Irvine 36 C/L motors. They do make a very nice Profile Carrier motor and worth trying in a sport class 1. Excellent power and great low speed.
Thanks
