50+, Thanks for the engine test scans, I love reading those old articles ! Actually, do you know if any magazine ever did a test on the Bullet ? I just bought a '49 model (with the heavier castings and squarish stack) which is spark, but I intend running it as a glow. They did actually make a glow version too, I believe. Are they good runners ? BOB

Might try getting in touch with the MECCA or SAM organizations. The engine collctors group has been helpful to me in the past, and the SAM Speaks magazine has had many articles in the past about these antique engines.

I have seen a number of plans that showed this engine in them, and if I recall some of hte adds in old Air Trails, it definitely was not one of the "Slag" engines.

If you do try to run it on glow, I'd definitely reccomend that you get a low nitro high castor oil fuel. If you don't want to try ordering Fox Superfuel from Fort Smith, get a fuel that has castor oil in it, and add probably 6 to 8 ounces of castor to it. Most of those older engines used a iron piston running in a steel sleeve, and by today's standards, moderate quallity bushing, if bushings were used on the crank, so they last longer with castor than with synthetic oil.

Thought someone out there would like to see this list for classifying engines for contests.

Just noticed, Twin-Stack, that the list pegs the Bullet as a .275 cu. in. displacement for Cl 3 Control line and B Free Flight.

Thanks 50+ ! Yes, the Bullet is quoted as having a 3/4 in. bore and a 5/8in. stroke for a 0.275 cu. in. capacity. For any newbies watching, the transitional period from spark plugs to glow plugs took place fairly rapidly. The difference was like going from candles to electric power overnight, and a lot of engine manufacturers simply deleted the timer assembly, and either covered up the ugly front end of the engine with a cap, or simply sold 'em the way they were. Some of my (glow) Twin-Stacks have had the front end partially machined for the timer, whilst others are still as cast. Photo's below show the actual engine I bought on the left, with a couple of clearer photo's of another engine on the right. BOB

ENYA 15 "Special" This engine (and 4 others) were hand built in the late
1950's by Akira Fujimuro, an employee at the ENYA factory and former Speed Champion in Japan. Based on the ENYA 15-IB, this Special has a twin ball bearing shaft. This same engine can be seen on page 158 of the May 1961 issue of Model Aircraft. BOB

1955 K&B Sky Fury .15 Twin - the weirdest feeling engine to flick over ! Not a great success, as they tended to run either flat-out or not at all.

On the left we have the rare ENYA 36, which was made for only a short time before it morphed into the much more common 35 Model 5001. On the right is a 3-bolt 19, lacking most of its (red) head & prop drive anodising - this being a slightly later model, very early 3-bolts with no anodising. BOB
