Dan,

I really didn't "need" the UCTKAM .09 I just got it for no real reason so nothing lost here. I do love the .049 stuff and have no interest in anything bigger anymore. I guess I thought it loked neat.

LAter,
Tim

DAN, you can contact BILL H. at [email protected] or 630-736-6036. I would have to call those guys who let go of those screamin' FF planes more nutz than some of us who try to control them!

Hey Tim,
I sent you a P.M, After seeing PT`s photos of the engine (I missed them before.) I`m even more keen to buy the UCTKAM .09 if you are still interested in selling it, I`ll pay postage to Japan.

Hey JM, in the interest of good will, I have to remind you that these Uctkam will not make a good airplane engine. The cylinder liner actually blocks the disc rotor outlet when in the airplane configuration. Will it run? Probably, but never fast.

Japanman

Thanks for the warning P.T,
I am not really concerned whether it runs in a plane- I may make a boat to put it in. I am more interested in fooling around getting it to go

Seems like an interesting engine anyway.

hmm... a boat. Now there's an idea I can sink my teeth into! Now to cool the head and get/make a foot.

Dan Vincent

PT,

Yeah, a Boat. Dumas made a neat little 22" hydro for a .10 called the "Lil Rascal."

I found a site with a kit.

Use an Octura Kool-Klamp #2, an OS .10 flywheel, reversed to clear the tuned pipe, and an early OS .10 carb. You'll also need a flex cable drive and a collet type prop nut.

Darn, I've got no excuse now!
I can't help but notice that there's nothing extra being done to cool the engine.

Dan Vincent

PT,

There is an Octura Kool Clamp wrapped around the head. Being a rear Rotary drum type you can't put a packplate cover on it with water nipples like you would normally do with a front-rotary type. I've seen many .40 and .60 hydros set up with no water cooling to the lower case.

Been some time since your post! I am now involved in 1/2A boating again and while searching about the Uctkam .09 I came accros that thread. I wonder if you ever tried that "Little rascal"with that engine and what it was like. There is lot of activity right now in that furum:
http://www.rcuniverse.com/forum/m_8498373/tm.htm
about 1/2A Dumas boats and other and also on RCG on the same subject:

Right now I am building for .049 power (Cox TD)but already think of the next step to .09 since there is more choice in props for that size engine. Opinions about the UCTKAM .09 seems mixed but it seem that a lot of the problems had to do with trying to use it as plane engine with the exhaust in the back,thus blocking the booster port! Since you're the only one to actually use it as intended I'd like to know your opinion.

Never got the engines to run in any configuration. I never figured out why, but the most I could get was a fraction of a second. Gave 'em away a couple weeks ago to a guy that essentially got the same results. He's more hard-headed than I am and he's into boats, so if anything changes I'll post an update. You are 100% right about the booster port being blocked in the airplane config. What a headache it was figuring that out!

Dan Vincent

I had a problem with a detached retina in my right eye a couple of years ago so never finished up that hydro. My right eye is like looking at a newspaper with a hole in the center.

I also have a Dumas fiberglass 1/2A Deep Vee kit around here someplace and also a Dumas cooling clamp for a Cox .049-.051.

Sorry to learn about that medical problem Dan, I was just wondering why that thread went silent so long ago. I am still curious about that UCTKAM-1.5cc and might get one just to look at it (HobbyClub has them for $ 50)and it might be worth the effort. After all even the Dooling 29 required lot of rework in its days to really shinne!

Dan Vincent

The main thing to remember is that it's ported to run with the drive and exhaust pointing the same direction as in a car or boat.

If you need a tractor configuration and have to swap the front and back ends a little grinding will be needed to open up the porting.

coriolan

In boat use the exhaust always go toward the drive for all engines larger than .45 (Picco,CMB,Rossi and OPS), some .21 have FIRE and other side exhaust but in NAVIGA FSR racing they are used with gear reduction which allow the pipe to be in-line with a FIRE engine. Out of curiosity would you consider selling that engine?

forsakenrider

DAMN! I really want a small RIRE engine, I have forever. Does anyone else make one? or do I have to get one of these and try and convince it to run?

Get one and convince it to RUN & run well ....... Dare yah.

forsakenrider

That sounds like a DARE! if no one else makes a small (09 or less) RIRE, I guess I will have to!

You got it... Is thet C/Card out yet?

Clean it before you do ANYTHING! Pay special attention to the fuel delivery ports and needle valve. In my opinion it would be more fun to wipe your butt with fifty bucks. Easier on the nerves, too. [&:]

There is alternatives used in Class-1 tether car racing in Europe, kind of look like the Uctkam-1.5 at 10 time the cost and the speed record for these is 268.697Kph! I am now very curious about that engine.
Here is the kind of car they are used in, there is some hair raising videos on YouTube about that kind of racing. Gualtiero Picco (the engine maker) has been involved in that for years and hold the record for Class-5 (10cc) at 344,959 Kph.

I'll probably never finish the boat so I would donsider selling or trading.

I'm looking for a Supertigre Bluehead .60 and want to try a slow moving trainer to see if I can see it ok with the bad eye. Other .60 engines also.

coriolan

Re-read all the posts in that thread..........and still curious, maybe I need to see a shrink[&o]PM on the way!

Hi Steve, that video (especially the sound) brings back memories. Back in the late 40’s and into the early 50’s tether car racing was popular in my home town. I arrived at the track one day while a car was running and even tho I knew most of the guys and their cars, I couldn’t tell whose it was until it slowed down. Just a blur and a zing, zing, zing. They were running Dooling 61’s. I don’t remember RPM’s or speed, I’m sure the streamliners today are much faster but that is the same sound that I remember.
One thing that struck me as odd is that they are running clockwise. Back then we all ran CCW. I wonder why the change? It must be performance driven. Planes, yes, torque favors clockwise but cars?
Al
PS. I couldn’t afford a Dooling back then but I did get (still have) a McCoy 19 car. Years later on a short tether in my garage it sounded like the real thing in the video and impressed (scared the crap out of) a bunch of my R/C buddies!
