This one will work on a plate hanging downward.
Hey dave i would appreciate some more info on that engine, looks like a saito but...

Odd though, the C/R is at 11.75:1, I'm only feeding the engine 15% nitro with 17% oil and I haven't been running the engine super rich. Hmmmmm
methanol has a very high octane rating. I donít think detonation is a problem with high compression engine. I do know I canít run my 180 HC on glow it will not idol but will run at full throttle. The CH ignition takes care of all them problems.

Sounds like a plan!

Yer darn tootin! perhaps when bruce get's the algorithm's sorted out on his saito gasket cutter he can raid his own stack and cut some cam cover gaskets out of a front page, you could spend hours putting it back together as a jigsaw.

Sounds like a plan Pete! If Bruce needs gasket material, I would be happy to donate a few prime Playboy covers to the cause. Must be the type of clear coat they use to make the paper glossy(?)
Or something on the paper anyhow

The Abitar production for a while was done by Gary Connelly , the same guy who made the 1/4 scale Chevy V8 engines and later took over the Perry Pump and carb production.

ABITAR 1.20 and 14 x 6


Bucket and shim lash adjuster.


My OPS 1.20, smooth runner.

Pete, that ABITAR 120 was originally the Conley 1.20, I owned both at one time. At $289.00 it didn't sell, Mr. Conley sold the rights and all that to a conglomerate. ABITAR moved the carb up to the intake port, hence the pump. It was a double overhead cam, four valve. It was claimed to turn a 14 x 6 at 12,000 rpm. My example turned a Zinger 14 x 6 at 12,180 on 10% fuel. 15% fuel would make it knock like crazy.
It's cool to do a Google search and find my own pictures.

The belt drive cam was the deal breaker that kept me from buying one .
I already owned a Condor 120 at that time. Pretty rare engine today, for good reasons! Kind of looks like a brick. A lot like the Laser

Wow Dave, 14x6 at 12180 is 3hp. That's amazing for a 1.20!

Yep, extra valves and superchargers are the right stuff for power. I've read the Conley engines had mechanical issues eg cam gears and con rods. I'm sure those issues would have been worked out given enough time but hey, lesson learned, don't try selling a premium priced engines with mech issues. It only takes a few people posting legit complaints about a product to kill a product these days.

If I get lucky and find a nib YS 115S at a great price I'll pick one up to put in my Strega, otherwise it'll probably never see air time. "It's all or nothing baby!"

I keep meaning to fire up my two YS and see how they run, but just never get around to it. A 110 and a 65. The 110 is destined for a Mustang if I can get it running.

And if you can't get it running , it could have a future at a certain hangar in Michigan. Of course, I would ship you a Saito of some kind in a once maligned white box, maybe two Saitos in shameful white boxes

I'd settle for a ys110 for my Strega. Send it my way!

I have a large string that I loop around the fuse and wrap 6 times around each side of the dowel so I can twist the dowel and move the nose up and down. Then a big heavy plumb bob is dropped dead center of the block and the tip is just above the area to measure. It is that simple. I have a very light weight plastic level, I think it came with the CG balancer, but not sure, and place that on the tail, then add weight were needed with minor adjustments of the dowel to keep the bubble level until the tip of the plumb is where I want it. Works perfect every time. Largest plane I balanced with it was the Rascal 168.

The only one I had problems with was the Biper Cub because I have no idea where the balance point should be on it and I made it too tail heavy.
Hey all.
So the bottom line on the VR rig is: the device is limited to verifying factory or otherwise obtained settings. Device can not set a flyable cg on a plane with an unknown cg setting. Simply stated , is this a correct statement
Yes or no.
Can't put this question to bed by any other means....

Yes, the Vanessa rig or any other cg machine will only tell you where your cg IS, not where it NEEDS to be.


There many factors that will determine the cg range for an aircraft. Wing planform, tail moment, tail plane planform etc.
If you don't have a reference for where your cg NEEDS to be (plans etc) there are ways to approximate. The cg calc is an excellent tool for doing just that.

Yes, it is just a tool to get the CG corrected, but you have to know where the CG needs to be, and a calculator is needed for that. I will have to revisit this once I get the Biper rebuilt. You know, I almost had it down on the ground in one piece but a A hole drove across the runway just as I was on final. Then trying to go around I started losing roll control, and finally dumped it as gently as I could.

Yeah the Rascel 168 is an inch and a 1/2 forward of were it actually flyís the best. Forward or nose heavy is where a lot of planís and kits put the CG for your first flight to help have a successful first flight.

Thanks for a straight answer!
I use cg calculators like everyone else when I don't have a spec.

​just looking for a faster easier tactile method. I was hoping the VR would double in that capacity.
Guess not.

A better view of the OPS 1.20 rockers, a tiny tube carried oil up the back and the oil puddled under the cam.

Seeing how we seem to be showing off pics of other engineís here is my favorite 2 stroke I have only had this engine in one plane but soon will be going in a unlimited racer.

66į and light S/SW winds today...... It's off to the field for me.

Wow,
I missed this gem

A negative comment about negative comments.
Two negatives make a positive, so perhaps that is a positive. If so, do I dare say anything negative???

Conundrums are such fun!
