Run out?? Ya'll must have AMAZING eysight! I sure can't tell no matter how hard I try.

How many of you are either mechanical engineers or professional engine mechanics?.. just wondering.. Sometimes its good to know the backround of posters.

Heck even the engine test stand was over the top as to quality and detail and all the accessories on it as well.  Although it isn't mentioned, I would not be surprised if they even had four valves per cylinder too.

I was just wondering about peoples backrounds cause it becomes part of the discussion. Either you know or dont know stuff..

That engine was made by one guy for his specific reasons. You can view his entire design, creation thread over on RCScaleBuilder.com if you so choose.

Why did you quote me? Are you asking me if I have ever built anything form scratch? Yes. Have I ever worked on an old manual Bridgeport to make parts for race cars? Yes. I have I ever worked on an old manual turret lathe? Yes.

My mechanical background began at 9 years old when I overhauled my first carb, a Rochester Dual Jet. It ran and didn't leak.
At 12 I made a 3.5 Briggs run like a 10.5 briggs without blowing up.
At 14 I undercut, deburred & polished the shift forks, sliders and upshift side of the gears in the trans of my 250cc dirt bike, dropped the cylinder by milling 2mm off the base then adjusted the ports back up to increase the dwell. Reshaped the squish band in the hand and shortened the header 20mm. Instead of polishing the intake, transfers & boost ports, I intentionally left them rough like fish scales to increase atomization. Bike ran like a 350 -400.

Can I appreciate these engines that guys like Gary Conley have been producing for 2 decades, YES! They are awesome. I am just tired of guys posting photos of cool planes, awesome engines, neat designs and every Tom, Dick & Harry ripping them to shreds for no reason.

I appreciate fine art, whether or not it flies.

Status: offline 		Because you seemed to be taking aim at my comments. I probably would not have said a thing, but it was presented like this was some "break through".... and the lead in of the film was over the top. It was like the guy was ready to market the product instead of finishing a one off or prototype. I think the engine test stand was almost as nice as the engine. Everyone of us has a voice and it is too bad if you cannot get us to say what you want us to say.

Status: offline 		I found that engine to be a very beautiful example of pure talent. I noticed the wobble of the crankshaft, perhaps they used a replaceable stud in the crankshaft in the event of a crash? Perhaps that got bent from tightening the prop down?

It almost looked like the crankcase was cast, but I couldn't tell without having an HD playback. Either way, its a very beautiful engine. Sounds great. I'd take the prop off and put a flywheel on it and run it on a Go-Kart.

I'll have to agree. I don't think some people understand what talent and skill it takes to design and build something on this scale. And lets not forget time. It took me 14 weeks and 300 and some hours to stuff a Cummins 6bt into a 98 Suburban..

I hate to say the crankshaft is not bent, it is a optical allusion along with the engine being on shock mounts.

Please just enjoy the post with no negativity. I wish I had half the talent of some of these people (or the money to purchase there items to enjoy them myself).

Have a Merry Christmas.

Boy oh boy!! It reminds me of Old Greek Proverb:
" Better to keep mouth shut and be considered a phool, than to open mouth and remove all doubt"
I agree with CM and a couple others who actually see the beauty in this accomplishment. It makes zero difference whether the guy is trying to sell something or not or its a "One Of..." or not. It is still a fine piece of equipment and I appreciate it

Status: offline 		I for one, can really appreciate the amount of time it must have taken to accomplish the engine build.
Back in the 90's, I built an Echo based 32cc twin. It is nothing fancy. The fact that I built it, tested it, and it still runs to this very day still amazes me. Not knowing how to do any of it, just basic engine knowledge and lathe and small hand made milling machine, it was a real challenge for me. Now, at age 63, I would never attempt it again, but have the highest admiration for anyone who does. I think by now, I have forgotten most of what I thought I knew back then.
Kudos to the craftsmen of the modern world!

John
