Tom, I wish I WAS Steve Miller! Actually, I was in a C&W band by that name, years before the movie came out, but I will admit that the line.."some people call me the Space Cowboy" was the inspiration for the name! Anyway, back to the subject! With your new info, I'm saving up for one of my own! I have placed an ad here on RCU looking for one, so if anyone would like to make a deal, hit me up! I'm willing to trade up or down, plus or minus CASH for the right engine! I even have some antique IHC stuff if you're interested, Tom! My Dad was a farm equipment dealer years ago, and I restored lots of Farmalls and Internationals, and I've still got my 1937 D-2 pickup! If my memory is right, I think I've seen you on some of the old binder forums, too! I might have some rare IH, Harley-Davidson, Indian, or Hot Rod stuff to trade, if needed! "Trading goods-TONS, Cash-not so much!"

What I haven't done is open it up and check the e clips on the rods--must do that!
Methanol with CDI gives you the best of both worlds. Cooler running, more HP than gas. Better fuel economy, lower reliable idle, vastly improved user friendliness and improved fuel economy compared to glow ignition.

And, despite popular myth, even though nitro will no longer be necessary for ignition, increasing nitro content will increase power output albeit at the expense of decreased fuel economy.

Been a while since I've poked around in here!

Does anyone know if a carb from an OS FR5 300 will fit directly onto this engine? I'd like to know if it fits, as I may be able to obtain one to replace the current carb.

Thank you SJN. I will switch to that one if this FR5 carb doesn't fit. Is one better than the other? I have access to an FR5 carb, if I can make use of it that is.

I have never tried the FR5 carb, or seen it .
The OS carb is of better quality....so that will allways be better :-)

Hi guys and gals! I'm looking for one of these engines, if you know of one for sale or trade, plus or minus cash! If we trade, you WILL come out ahead! I need one for my Grandpa-Grandson project. Glow or gas conversion is fine! I have planes, engines, hot rod and vintage car, tractor, and motorcycle parts, even a good-running car or two! You just never know! I'm want one pretty bad, but cash is tight, so trades are KING! Call: (919)-770-4931 ANYTIME! Serious callers only, PLEASE! (I've had a few crank calls!) Let's make this happen! Check my ratings, I'm on the level! Blue Skies!

Yep, read it myself a few years ago on one of these threads :-)

Borrowed the the carb from my os91FS powered vario helicopter 4 stroke engine, and put it on the radial.
It did not run different, but it was easier to tune.


As you can see, it was easy to remove and test on the radial :-)

Hi Guys! I'm still looking for one of these engines, if anyone has one available. (See earlier post!) I missed the one on "The bay" that sold for 500 bucks, with a HUGE box of balsa! (I think I know who got that one!) Lots to trade, plus or minus CASH! (919)-770-4931 ANYTIME! Blue Skies!

Unhappy I finally got one....Now what?

Howdy all! I finally got one! (I don't know if it's a blessing or a curse yet!) The guy I got it from took it off of a Great Planes Giant Stick XL ARF because it didn't have enough power for "Vertical!" Really? My engine was converted by Adrian at C.H. Ignitions, to run on gas at a 20 to 1 mix ratio. (with a 20% loss in power, from what I've read!) From what I'm seeing on youtube and such, the engine appears to be rather heavy and under-powered, since they're mostly used on 71 to 85 inch wingspan War-birds, or 72 to 77 inch wingspan biplanes! Some seem to struggle, even with that! With all that said, am I safe to think that my engine would probably be fine on my old Pica 1/5 scale Waco? (kit built, not an ARF!) It's currently powered by a Saito 180 4-stroke, which flies it well. It's sad to think that a 64cc, five-cylinder radial only puts out the power of a 30cc 4-stroke engine, or do I have my wires crossed? I've read this entire topic from start to finish, and like so many others, I can't afford 4 grand and up for a radial engine, so this is the best that I can hope for! Any ideas would be helpful. What would be a good guess at all-up weight, minus the engine, mount, ignition, batteries, and such? (almost 7 and a half pounds!) 15 to 20 pounds? I'm scratching my head here, because I've not seen any REAL power figures posted anywhere, that I can use to draw my own conclusions concerning what a good airplane candidate for the engine might be! I had hoped to use it on my 100-inch wing-span Lockheed Vega, but since it's an old-school build, and probably over 20 pounds, I'm not sure if I should risk it. That would make it easily over 27 pounds, all-up weight! I still need to find a Keleo exhaust ring, too! My confidence is waning.....HELP!!!

Cowboy, I would suggest a 1/5 Corsair for this engine as it balances out the plane nicely and it's well documented the power is more than enough (even gas conversion). Plus it's a beautiful bird!

My stock G62 will swing a Zoar 22/10 to 7,000 rpm and weighs 5.5 lbs with the spring starter. My ASP 400 cdi converted on 5% nitro glow fuel with a Keleo exhaust ring will swing the same prop 6,300 rpm and sounds a whole lot better. Properly tuned the engine will make plenty of power for scale flying.
