What is it ? This engine showed up at the club meeting Friday

Looks like a "Plumber's Special"; and with a Hell of a prop on it!

This is a toss up. I would go with Fred or George.

Yea I figured I would get some remarks about the prop, The engine belonged to Hewett Phillips and he flew speed in the forties. I think the tube is a second port for a early schnuerle ported engine.

Is there any evidence that this critter actually ran? The vertical "chimney" is obviously the air intake, with a siphon feed from the fuel tank. Is there an exhaust port that doesn't show up in the photos? Otherwise, that curved tube might be intended to regulate rpm as the model proceeds through the stunt pattern's climbs, dives, and to avoid the dreaded "windup" when the wind blows briskly.

It is rear exhaust , small holes right above the intake.

Does it come apart Willis, or is it all soldered together? Is there any compression at all? Looks like something I could build. Is the cylinder a copper tube?

Willis Swindell · « **Reply #7 on:** October 17, 2009, 08:08:16 PM »

Russell It is a stock engine that has been modified for something . I am just trying to find out what the name of the engine is. It is about half the size of a 60 engine of that era.

Could those threads in the back of the engine be the exhaust???

Bill Gruby · « **Reply #9 on:** October 18, 2009, 07:45:56 AM »

Matt;

Look closer, the exhaust is the 90 degree stove pipe. The NVA goes right thru it.

Willis I came up with a couple of close look alikes. There has been some major surgery to that engine. It is hard to nail it down. I will keep on looking.

Bill
The exhaust is small round holes above the intake like the GHQ it would blow right by the intake. That is probably why it has the 90 deg bend.

Thanks for the pictures in the email Willis. I see now the stove pipe is the venturi. That scavange pipe in front has me at a loss? I will keep looking.

My take on it is that the tube running from the LH side of the case below the cylinder up to the front of the cylinder is the By-pass. Since the exhaust and the intake are both at the rear of the engine I would think that there is no bypass on either side of the cylinder. This would make it a cross scavenged type. I also would believe that the tube is silver brazed (sometimes called sliver solder).
It would be interesting to see it disassembled.

Any body got any info on it yet?

L0U CRANE · « **Reply #14 on:** October 21, 2009, 10:22:55 PM »

I'm with BigIron on this...

Looks to me like a side-port engine, with no volume added along the length of the sleeve for the bypass - hence the curved tube from lower case to/thru the sleeve where the piston top uncovers it after the exhaust port(s) open.

The finned upper 'unit' looks like it may be from some production engine, but most of the rest does look like home-engineering. And that's NOT a 1/4-32 or 3/8-24 spark plug, either...

Interesting to learn more about who, how and when. (Let's leave 'why' out of this?)

You don't know what I want to call it ! Hahahaha . Could you add it to the fox hurl ? I could really get in to giving it a good heave ! Hahahahah. Let us know how it runs when you get it going . thanks for sharing it never seen one like it . Might be worth a bundle

Victor Jeffreys · « **Reply #16 on:** November 11, 2009, 03:57:10 PM »

It's not an engine, it's a miniture liquor still.

Steve Helmick · « **Reply #17 on:** November 28, 2009, 06:36:07 PM »

Does anybody else think that the funny curved tube from crankcase to mid-cylinder is intended to send oily fuel to lubricate the rod and shaft? I don't see that it could do anything else. $:-\$ Steve

Greg L Bahrman · « **Reply #18 on:** November 28, 2009, 06:40:32 PM »

I think it's an external boost port.

Tim Wescott · « **Reply #19 on:** November 28, 2009, 11:27:57 PM »

It looks very homebrew to me -- I know that some early gassies had a soldered-on bypass, but the ones that I've seen followed the Brown Jr. tradition of a 'u' shaped bit of metal going straight up the outside of the cylinder, not that Borg-inspired tube that you have there. Further, aside from that curvy tube I see no provisions for a bypass at all.

I'm not even sure if it'd run for long if that's really silver solder -- AFAIK gassies want to run hotter than glow engines, and need to have stuff like that brazed on. I suppose it could have been designed for spark and methanol fuel.

I'm guessing it was an early effort by someone building his own engines. Certainly the quality of the soldering is something that you wouldn't see on a production line unless the manufacturer lacked a lot of pride.

If you're really interested, www.modelenginenews.org has a "whazit" section -- they'd love to get some nice detailed photos of that thing.

I'd call it a POC 35
or maybe a POC 40
I'd have to measure it to be sure

Claudio Chacon · « **Reply #22 on:** December 03, 2009, 07:31:23 AM »

WOW! I've NEVER EVER seen such an engine!
It looks a bit spooky!

It even reminds me one of those torture devices shown in the "SAW" movie saga...

And to think that with that engine someone may have settled a new record...amazing!

Leo Mehl · « **Reply #23 on:** January 03, 2010, 04:26:58 PM »

Boy- Have been around for a long time and I have never seen an engine like this eventhough th GHQ seem to be of the same breed. anly this is a lot smaller. It's got me scratching my head and other parts!

Scott B. Riese · « **Reply #24 on:** January 08, 2010, 09:19:58 PM »

OH COME on GUY'S....That's the engine that your DENTIST used with that flex shaft roto-bit.

Seen it, YEP I have...many thimes
