The regulator will be depending on .25 of a psi to push fuel through it. It would be an interesting bit to add to our learning curves. No mail today for good stuff to come except from Amazon.
This one will work on a plate hanging downward.

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

Next time I need a Saito gasket that I don't have on hand, I will order a back issue of Playboy from eBay.
Sounds like a plan!
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.

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

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 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.

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 fly’s the best. Forward or nose heavy is where a lot of plan’s and kits put the CG for your first flight to help have a successful first flight.

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.

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

66° 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!
