MOJO65-9or10

Anyone ever try to put a nitro car engine in a smaller plane? I would think that if you cut down the cylinder head fins a bit and stuck a tiny high pitch prop that they would be good speed engines. I know that some turn up to 30+ thousand RPM's but if it were proped right, it might be fun. Maybe there are no props that could handle the rpm's. I know from what I have seen that they seem to be WOT type engines but man they just SCREAM.

I,m not sure but doesn't the car engines run in the opposite direction of the airplane engines ?

Heck ALL I know is plane stuff, but I do know they scream. I,m look'in for a ripp'in engine for a pylon job with =/- 400sq inches of wing area. I was thinking about a .46 2-stroke but they are a little to heavy I think. I also was thinking tonight about that new Norvel AX-40. It is suppose to be a pretty good performer AND weigh about 3oz's less than a typical 40 size engine. Any suggestions? I really can't afford a Jett or anything like it, but I sure would like to. Maybe this little plane will have to wait a while until my income goes up a bit.

I ran an O.S. .21 SE car engine that I turned the heat sink head down so it would not cool that as much. I ran it at 23,500 with Macs header and pipe, an 8.5X4.5 prop and 25% fuel. I had it in a Jetfire 20 that just screamed. I lost it when I had a mid air. At the time I could not find an engine in that size that was a total screamer.

With the right prop and pipe an R/C car motor could work but you first have to work out the prop drive washer problem. Most hi-performance car engines have a pilot shaft crankshaft without a drive washer. But a lot of the milder, less expensive car engines do come with a threaded crankshaft and a drive washer - such as the OS .18CV-RX. Only thing is these milder motors aren't tuned any different than an airplane motor so there's not much benefit. If you are looking for a hot engine for a 400 sq in airplane then the OS 32SX is a good choice. It's more expensive than most engines it's size but it is extremely powerful and easy to tune. GMS and Thundertiger make similar engines that are significantly less expensive but they don't have quite the same power or reliability track record. If you are willing to spend more you can't go wrong with a Jett. If you haven't checked out Jett Engineering's website yet I strongly recommend it. Neat stuff, even if you're just window shopping.

irvine 15XR comes both ways check Just engines site I have the aero with the MVVS mini pipe from them
