Just look at the character of that Feeney the Kalt is pretty good too.
Great photo of the two side by side!

Ref to post #146 on the 'Centra' engine, these scans are from one of the handbooks by Mr B.O. Glas.
His books contain several educational examples refering to model engine components.

These illustrations show the sequences of crankcase mould making (sand cast).

Forster .29 rear disc induction

Hi,

Well, this is my one and only 'ignition treasure'.
As my modelling debute took place just as the diesels were conquering Europe, I never built up the same 'in my heart' relation to the 'sparkies', apart from my overall interest in model engines of course, and old technical stuff as a whole....so, one ignition engine, representing this chapter of the history book, is ok with me...

It has been years since I last test run this Forster.
Using an 11x4 wooden prop, it ran sweetly, and acheived, IIRC, about 6500-7000 rpm.

Even though I ran it with ordinary mineral oil, and 'conserved' it with same, I noticed it had began showing signs of sticking, and today I partly dismantled it for cleaning and re-oiling, taking some photos in the process.......
(sorry, some photos aren't too sharp..)

Sometimes you get an engine so beautiful, that it should be on display in a museum somewhere. Such is this Miniature Motors Torpedo Special which originally belonged to Ted Enticknap. BOB

Bill,
The engine was a good looker but the cylinder is loose I put her on the test stand and bumped the exhuast stack and the cylinder turned about an 1/8 turn out of register beyond the normal position. I'll take it with to the next SAM contest to the Jack Van Dusen of Browns Only and see what he says. I wasn't going to force running it in it's present condition.

Bill, around 1948-1950, McCoy and Dooling had racing engines that initially were spark, then "converted" to glow very successfully.
When was the last big year for the sparkies, and when did glow first become dominant?
I can remember when the McCoy .60, glow, was selling for $27.95.
I had a used McCoy .49, glow, that ran well, but was very hard on glow plugs.

Way back then most of the ignition engines were only being run for less than a minute in free flight planes. When control line became popular, the engine run times went up and then the reliability issues and run time problems began to pop up. Getting a battery small enough to last an entire flight on a control line model was a big problem. Then the engine started to overheat as it wasn't designed to run that long too.
Many of the old ignition engines didn't do well on glow plugs and glow fuel. The cylinders were usually held on with two or three small screws, and tended to have metal failures.

I had four OK Super .60's and a couple of Madewell .49's I wanted to use on some SAM RC free flight planes, but I never got around to doing it, so I eventually sold the engines to a guy in New Zealand.

here is one of them A OK Super .60:
