How about a 180 (30cc) glow motor?

[Ian Inverarity]

The rules of the AMPBA (Australia) provide for X class motors up to 30cc. As far as I know NAMBA has 30cc for X class and IMPBA has 30cc for F class.

With the one notable exception which I own, nobody makes a 30cc marine racing nitro motor. Wouldn't it be nice if manufacturers like CMB etc did a 30cc motor?

Andy Brown seems to be pretty flexible on getting motors made, maybe he would be interested in making a Mac 180! Would anyone else be interested in a SERIOUS motor for the X class???!! Someting that would put those gas guys in their place! (whoops, I am a gas guy!)

That would be sweet!!

single cylinder would be nice and simple!! imagine the fuel bill!!

 

[Ian Inverarity]

Single cylinder would be nice and simple, and reasonably light!

Fuel bill would be no worse than your twin!

A serious single cylender glow motor bigger than a 1 cube is something I've been wondering about for a while. a MAC180, K180 etc pleeeeaaaaase build it for us.......

There are a coupel of twin cilinder 30cc out there outher than the A180

CMB have made a side by side twin but not for production and there is a inline twin made by MHZ in Germeny.

K180 would be awesome!!

 

[Ian Inverarity]

Ozzy,

I wasn't counting those other engines. But as you say the CMB is not a production motor, and is really just 2 90's geared together anyway, not a true 30cc motor. I had forgotten about the MHZ, but it looks pretty heavy, and I guess it would not be cheap. I was referring to 30cc single cylinders to keep the whole idea economic.

Hey Craig,

Talk to the factory about a single cylinder A180-HP! 8)

a guy over at Jims RC Boat dock is converting this to gas.

Oh Yeah,

Forgot to say no rings......

 

[_laxmasta2039]

that'd be cool, imagine what would happen if someone tried to sell one as an "excellent weedeater motor" and it was bought and put to use trimming weeds ;D ;D

[ "what the f----!! honey, the new weedeater just cut a large hole in the side of the house, all i did was move it a little closer to get at the really stubborn weeds..... :- "

no really,

i like the idea of shutting the gas guys' whining about big boats not being able to keep the >100 trend going.....jeez, i bet a nice 30cc nitro and a lot of hard work could break 150mph in it's first week of running!!

Hey hey hey!

This thread is not about slamming the gas guys! I am one, remmember! ;D It is the growth area of the sport currently anyway! They do plenty of slamming of the nitro guys, (see Jim's boat dock) there is no need for any of that here!!!!

The OS is 35cc? so too big. That looks like a nice bit of work on the conversion tho. Also the OS BGX1 is a low performance aircraft motor, so does not have the correct layout.

Tim,

If we are getting specific about layout, yeah no rings. Rear carb, front exhaust. ABC piston/ liner set. Steel rod. Crowded needle roller bottom end (and top end!). No gudgeon pin circlips (A-90 style). Double sided crank like A-90 or CMB Evo, or long well supported single sided crank like K-90. Disc induction like A-90, or maybe ballraced drum like K-90. OS style carb! Anything else on the wish list? How about porting and bore/stroke like a Novarossi 21!

Yeah but it bombed out!

I would like to see a drum valve - a really big one supported by bearings, a 1 piece crank that won't run - out like the CMB's, but with a good crankpin so that it doesn't shear off like a Picco. I'd also like to see a titanium rod with needles top and bottom, a billet piston with large pin bosses and a large gudgeon with teflon retainers.

Lots of head retaining screws - say 12, and a head with plug body cooling passages close to the plug threads. The bore and stroke ratio would be interesting, Having a large capacity the bore size and the relationship of the plug to combustion chamber size would be tricky. I do not like multi -plug heads but it might be needed for a motor of that size.

Tim,

were you going to say something there?
