Here is one I got, a Saito FA-90T twin R/H cylinder repaired with solder.
If anyone has one I'll be happy to buy it, the engine is near new.

Model Engine Gallery Page 14

The Charlie Tomalesky Gallery Page

Some time back a beautiful drawing of one of the old engines showed up on here and people wondered were it came from. If you look at Ron's Engine page, page 14 of the gallery, you'll find Charlie Tomalesky did the beautiful rendering. http://www.modelenginenews.org/

Diesel engine : Displacement: 2.47 cc
Bore: 15 mm
Stroke: 14 mm
Weight: 165 g
Induction : rear rotary valve
Origin: Believed to have been developed and manufactured (circa 1985) for F2C by two experienced (German ?) Team Race modellers. The carburetor is missing because in Team Racing a special design is used.

Glow engine : Displacement 4.84 cc
Bore: 19 mm
Stroke: 17 mm
Weight: 237 g
Induction : rear rotary valve

Barry, the two smaller ones have to be related to those shown in Post # 5856 !
What intrigues me more than anything else, is the fact that some of them appear to have the glow element built into the head, in a similar fashion to the 1948 H & H 45. More info please !

First came the dual needle valve idea (see bottom row, a rare FOX 29 Stunt from 1954), alternating between a fixed high & low speed. In between that crude system and the first simple throttles, came the rotating exhaust valve as typified here by the 1957 FOX box art. The rotating rod had a "waisted" or flat machined section in the middle.

My R/H one seems the same as the R/H one in post #5856 and has a built in glo plug, the other two have normal removable glo plugs. I looked up the H & H 45 and they are close except the H & H doesn't have webs on the crankcase coming down to the beam mounts. I don't know what else I can tell you, there is nothing on the engines whatsoever apart from me checking the capacity.

In Twin-Stack's pics of the Fox .35 RC, its interesting to note the off-center glow plug location in the Fox .35 head.

The large L/H is 24.24 X 23.22 10.71cc .65ci
The middle is 16.70 X 18.36 4.02cc .24ci
The R/H is 16.73 X 22.00 4.8cc .29ci
The middle one has a prop drive with an adaptor to suit a boat prop shaft as well and the two smaller ones are very similar in construction, they also all came from the USA.

Steve, that head was a special one-off, just for that engine. Some came in the specially marked pink / black / white box above - others in the standard 35 Stunt box as shown below.......

I had one of those Fox .19 RC Specials around 1964. In fact, it was my first RC engine. I could only get my escapement and linkage to work erratically, but the engine seemed to have a very reliable idle. Didn't have a tach in those days, but I was guessing about 13000 full speed and maybe 2500 tp 3000 on a 9-4 prop. It would idle for a full 4 ounce tanik, and then if I could catch the quick blip, almost immediately spring to full throttle without hesitation.

Hello !

Do you know if the F2C engine is from east germany ?
Some Parts look like a heavy Modified BWF.
Is it possible to show the engine assembled without the head ? when the liner ends at the top of the piston in upper position, that could be a clue.
I know the designer of the BWF personally, so i would ask him if he knows anything about this engine.

Regards !
