Here's my current favorite among my "mixed parts" Cox inventory. Late 90s Baby Bee with an old single bypass cylinder and piston, Valentine turbo plug head, O'Donnel hot plug, and an .049/.051 timing shim under the cylinder. The intent was to put together a detuned Baby Bee that would not drill my kid into the pitcher's mound when flying C/L on 30 foot lines. It turned out to still be stout enough for basic maneuvers like wing overs and loops but almost tame enough for an 11 year old. Marginal power with the prop on backwards and just the way I wanted it for level training flights. Very nice with a 6/3 for vintage 1/2A C/L fun. BTW, the hot turbo plug was chosen for using low nitro fuel and works nicely since the engine is a bit short on compression and is run a bit on the rich side most of the time.

Here's another engine that morphed over the years. This started out as an R/C Golden Bee used with the the exhaust restrictor ring in a fixed position for taming single channel R/C flights in the late 60s. I've never understood why Cox would ship this engine with the stunt tank and a backplate with two filler spouts. I used to stuff them with round plastic toothpick stubs for C/L use and am now very glad that I never modified the backplate at all when I was a kid. This engine was one of the few survivors of the great basement purge at my mom's place in the early 80s since it was one of the few engines I took with me to graduate school. I still muse about the long gone pulse equipment, all the engines, and the various ARF Cox C/L planes and a couple of Cox and Wen Mac cars that disappeared to a church rummage sale...

These days the engine serves dual purposes. It has the Davis HD crank and runs as a diesel for retro single channel R/C and with the Cox stub exhaust for "muffled" C/L power at the local ball diamonds. Both applications use a single bypass piston/cylinder unit. The original cylinder/piston wait in the "cigar box" for a restoration to stock someday. Here it is mounted for the beauty shot on a Brodak Cessna being readied for the Fall flying season. The Valentine prop nut is for ZOOM and the sure start ring and spring to save the kid's fingers. Nicks we all lived through forty+ years ago are "near fatal" incidents these days.

Thought I would add a recent one I did after being inspired by these designs!

Its a Babe Bee with partially ribbed tank, large no drag drive hub, and blue spinner.

Regards, Matt.

Recieved a Killer Bee backplate from XenaLook a few days ago
and assembled this.
Goldan Bee lower end with a "0" cylinder assembly and standard golw head.
The prop is an older 5 1/2-4 Grish tornado, just for eye candy.
Not tested.

That would be a Space Bug Junior from 1953 or 1954, the only years they were made. The starter spring is an add-on...they were not yet invented in those days.

Here are my three: Note that the firewall had to be drilled for the intake. The Babe Bee was the first Cox flush-mounted engine. The mounting holes are the same as later tank-mounted engines. The cylinder and glow head threads were smaller than later ones. A new cylinder will fit on the old engines though. The Space Bug and Space Bug Junior had the fuel pickup as an integral part of the tank.

Since I took these pictures Bernie and Xena had prop nuts produced that look like the originals. These three SB Jr's and a Thermal Hopper have received them.

That old prop nut looks great on that engine. That's the type I was referring to in my previous post.

I have never seen one of those Grish clear props. I remember Cox and Kaysun having them. I went from the Tornado Plasticotes to the Tornado nylons (first white, then yellow). I am guessing that it is plastic?

Nice engine!

Both are Valentine engines. The one on the left is a Speed Bee, the one on the right is a Speed Bee II. I have not run either one yet but I am definitely looking forward to running them. I hope to have one on a Skydrill. If I am really lucky it might happen within the next year.
