OK cool, come to think of it a fuse might be problamatical right behind the prop, Duh. Sure have come a long way with Ukie throttles Eh, I love my Bill Young electronic handle. Now I got a question for you that you may be able to help with. I would love to get my old Holland hornet running and perhaps build something for it. I know RJL list glow heads for them but I don,t think they ever really made a production run or perhaps I just never caught it. Any thoughts on getting functional heads or a mod for something else?

John

John,

I would suggest you get in contact with AJ Coholic to see if he could machine a standard HH glo head to accept a conventional plug or maybe a glo Bee.

AJ posts a lot on the diesel forum.

Dan,
Nice pics. I should have known you would have them...especially since they are .09's.
The review I mentioned must show a picture of the POGO. The head has the shiney part (like a Spitfire), the backplate has a backplate similar to a Spitfire .065, and the it has the long intake, but no taper.
Perhaps it was a prototype.

George

George,

Yeah, the machining on the head and backplate are a dead give-away to the engines' Spitfire heritage.

John Brodbeck told me Mel Anderson was a guy who loved to do complicated machining operations when he could have just machined them round.

I don't have a good picture of the POGO head or backplate but one shot shows a bit of the head.

Compare it to the Spitfire .065 and the backplate is machined the same way.

Also, note the cylinder and head profile look the same on the Pogo .091 and Spitfire .065.

Thanks Dan I'll research that maybe get it done locally.

John

I had never seen a POGO in the flesh and tried to get one off ebay. Finally one came through that had been owned by someone whose only tool was a pair of pliers. Got it cheap. Started first flip and turned a 7x? very nicely. I could never figure out how to get it mounted and etc. in a plane I wanted to put it in, so put it back on ebay as a good runner and made a couple of bucks. Nice little engine. Someone said they were originally designed for a tether car.

Jim,

You must have picked up the POGO without beam mounts and someone removed that black plastic radial mount.

There is a large gap between the case and the backplate so it's possible to make a ring mount to fill the gap. Once you tighten the screws to a firewall, everything tightens up.

Here's a shot of both the POGO and PAGCO as they had the same style. The ring mount would be similar to a K&B Infant .020, Torpedo Jr .035 and Torpedo .049.

Mine had beam mounts. It was a matter of getting the tank in the right place and making things look the way I wanted them to. I'm going through the same sort of thinking with a Space Hopper, although it is a different kind of problem.

Jim

I have a Baby Spitfire radial mount with no way to mount a fuel tank to the back side.
Any idea what year it is? It has a metal(AL) prop.

mro:

Your Baby Spitfire is probably around 55 years old. It is the engine that was recommended for the “Firebaby,” one of the very first ARF airplanes. And it was long before the term ARF was coined. The airplane had a balsa profile fuselage with an aluminum firewall, a bubble canopy sat on top of the wing with a supplied fuel bladder tank inside.

The airplane was also supplied with a stamped aluminum propellor, quite possibly the one still on your engine.

Yes, I had a lot of fun with my Firebaby.

Bill.

Bill,

Thanks for the info.
Does this engine have any value. Do you think it would sell on Ebay?

Thanks

mro:

Sorry, I hae no idea what your engine would bring on the market, I'd suggest posting in the 1/2A forum and asking about it.

EBay? If the price doesn't xtart too high, almost anything will sell there. Might not be as much as you think it should be though.

Bill.

I believe the Baby Spitfire is of .045 displacement. They also made a Spitzy .045 with tank included (see pic...reverse pitch prop for pic only). There was also an .049 (several actually..second pic) and the "Royal Spitfire" .065 (3rd pic).

The Baby Spitfire was made to use an external tank (not connected to the engine). It would be an excellent engine for one of the many Scientific "Hollow Logs". You mount the tank in the fuselage and run tubing up to the engine.

The engine was made about 1950, give or take a few years.

I would not use the metal prop. I would try a 6x3 wooden prop...because the crankshaft is small and you wouldn't want to bend it. Use 15%-25% nitro fuel with 22%-25% castor oil lube. If it is new, break it in properly. Remember, this is OLD technology.
