Sounds like a reasonable request. Let me see if I can't take a shot or two today and get something posted up here tonight.

Hi Tailspin,
They're the CM-6 plugs, angled. I just got it a couple of weeks ago.
I'm trying to get time to post the photos I took earlier of the engine and the cowl, but the wife has me on heavy-duty repeating honey-do runs to the store, what with Thanksgiving "on the morrow."

Try these photos:
Man, I have to say, from looking at the first photo, the cooling holes in the cowl couldn't line up any better with the cylinders if we'd planned the plane around the engine.

Question!
What thread size is the center of the shaft? The specs didn't show it, and Tru-Turn needs to know to provide me with the correct cap screw (to secure the front of the spinner) while they're doing the machining on my spinner. The rest of the specs have been really helpful.

I was working on the mounting of the engine yesterday, and it occurred to me that in this RC Guys 33% Pitts S1 ARF, there's no way the exhaust pipes will go anywhere near the bottom of the fuselage, much less extend through the cowl.
Not a problem! On one of my last planes, it took a lot of research to find this tubing, to be used for the same thing. I dug it out, and Viola! It fits like a tight glove. Just use a small fuel-line clamp to secure it. I took some photos here so you can see it in place. One of the photos is of the receipt, with the information you'll need to order your own tubing.

BTW- regular silicone tubing will work okay as an exhaust extender. Teflon is bullet proof but 3x the cost

Yes, the tubing was between 25 and 28 bucks for the total tubing with shipping, as I recall. Good stuff, though, and it gets the job done nicely without any fuss.
Normally, with bolt threads being so close, I wouldn't worry too much about the fit. With this 3-1/2" Tru-Turn anodized spinner, I figure it's worth exercising some caution about getting a good fit and nothing coming loose, since the spinner costs a goodly amount. Heck, I've bought whole kits that cost less.

I got a mail from Tru-Turn today that said that their 10-32 bolt threads will work just fine in the Valley View 40CC shaft thread, so there's some good news. One less detail to agonize over.
I keep telling myself, "This is FUN, Jim, remember that. This is FUN!"
It sure is fun being OCD. Oh, well. The planes always turn out really nice.

Yes the 10-32 bolts will work but I would use an m5 unless you cannot find them but most hardware has them?

Hey Guys, took out my 3DHS BigFoot today for the first time in a month. 40 twin fired up on 3rd or 4th flip like it had been waiting to run all month long!! My low idle is now so smooth, even down to 1450rpm! Peak was around 72-7300 with a Hover carbon fiber 20x8. I love this little jewel more and more!!

Hello - I have a VVRC 20 in my Aerobeez 20CC Extra Profile. The plane has 14 flights and the engine has .7 gallons of fuel through it.
When I first installed the VVRC 20 it ran great with a slight midrange burble. I would get a little gas spray off the carb but nothing major (being a profile I can see the carb while the engine runs). Yesterday I did 5 flights and it is really starting to spray excess fuel on the firewall and fuselage. The engine is running rough inverted at mid throttle, and the plane takes a while to fully spool down while at idle for landing. I few times while in the flare I heard the RPM drop.
I tuned the engine again which helped the midrange a little. My high needle is at Peak and the low is set around 7/8 turns open. This results in a perfect transition from sitting at idle for 60 seconds.
I am still getting a lot of excess fuel spraying off the choke butterfly.
Any suggestions?
Thanks!

Yes, sounds like the reed block needs cleaned up. They are supposed to be closing tight against the block during crankcase pressure cycle. Any leakage would go right back out the carb. How do you like that plane and setup overall?
