RE: RCV engine
I use the RCV 91CD, great engine, 90 size 4 Stroke with demensions of a 60 size, I have it going into my H9 60 size P-47; the SP type RCV I have not used, interesting engine, would fit well in many warbirds; the cooling of these engines as they run on the hot side seems to be the concern; example, on a P-51, P-40, Spit or ME 109, the spinner blocks any cooling, suggestion from RCV is that you have to use a metal spinner to serve as a heat sink, I have also heard that its a problem keeping the pressure line at the nipple from melting, even silicone; thats just what I have read; lots of discussion on the British RC Forum, its at RC Flyers, I think, do a search, lots of info on RCV. My 2 cents worth.

Can you post some pictures of the RCV installation in your P-47?

RE: RCV engine
It will be awhile before I get the plane built to that point, I have a habit of tricking out my ARF's with scale enhancements; I will say, that I placed the 90CD against the firewall and not a bit of it will protrude through the cowl, only an exhaust pipe out the bottom; check the "ARF forum 'H9 60 Size P-47 Build & Fly' thread", probably page 4 or 5, somewhere in the middle, a guy posted some pictures of his RCV 90CD install on this very plane; he installed his horizontally, I will do mine at a 45degree inverted install.

RE: RCV engine
Hi All
I have the RCV120. I was going to use it to turn a scale 3 blade for my 80" 109. It turned the 19.5" arc blades at aprox 3500 rpm. Not bad considering it has 1.89 hp 2:1.
So I have decided to use it in a 70" span Hurricane with a scale 3 blade or a 62" span 109F with a scale 3 blade.
Cooling is a bit of a concern, so I guess I'll try to fly on cool days.
Over all, I like the engines concept and compactness. On the test stand it was easy to start by hand and idled very well even before the recomemded 2 hour break in

RE: RCV engine
I'm interested in these engines because they wouldn't mess up the scale appearance of my warbirds. On the heating issue, is there a way you can build baffles inside the cowling to duct air directly to the engine?
How much will the muffler protrude on your 80" 109?

Kinda like this.
I had started this spinner, but mever finished cutting the beveled slots draw in air as it turns. I think it would work though.

This should allow no inlet holes at all!
Has anyone tried this or something similar?

Well, I know of at least 2 people who have installed the rotary cylinder versions into 1/8 scale Top Flite Corsairs: "Juice" & RocketMan. I remeber that RocketMan has the .90, and he reported that he was quite satisfied with that engine in his plane. Don't know why niether of them has come forward here.

RE: RCV engine
The radial models are nice with the RCV, the cooling issue would not be as much of a problem. I think the real challenge comes with the liquid cooled inline type of models.
Juat as a matter of info:
According to my emailed temperature question to RCV, they answered, the normal operating temp for the RCVsp engines are between 315 degrees F to 350 degrees F at the egxhast port nut location.
