Hello Diesel lovers!
    I just came into possession of a PAW 55 BR ball bearing diesel engine. I have been reading the magazines and such enough to know that this is a pretty decent engine. Lots of paper work came with it and I have determined that it is of .03" displacement. I have just started to have an interest in these things for some reason. Wish I would have done this while Jim Thomerson and Jim Wilson were still with us. They were two of the best I ever saw with diesel engines. My question is, this thing is a pretty powerful engine, am I correct? I was initially thinking that I could put it on a model that is usually powered by a TD-.020, like some of the .020 OT Replica models. What size/weight free flight model and/or control line model would suit this engine? I think I have the plans from AeroModeller for the TomBoy and would like to build that. I plan to find the ingredients for fuel and mix up a small batch and bench run it to get used to operating one. I have some old McCoy diesels and a few other imports to try and run also.  I recently won a copy of Dr. Diesel's book on eBay and will use that as a guide. Thanks in advance for any and all guidance and suggestions.

Hi Dan, a friend of mine has one of these and we've used it for a lot of flying (CL). They are really nice little engines and highly thought-of. I don't have any other engines of that size (or a TD 020), so I can't really say how it compares power-wise. My guess is that it's pretty good, though, and your idea of a TD 020-size model would be fine.  Maybe something a bit bigger, even. Expect to use a bigger prop than the TD would - something around a 6x4 seems about right for CL.

My friend had his in a slightly enlarged Stunt Chimp. It was quite capable, and surprised a few people. I can try and find out the dimensions, if it helps. They're a nice engine to use, and not fussy with settings. Just beware flooding it - you don't really want more than about 1 choked turn, plus maybe a touch of fuel against the closed piston.

.061 x .55 = .03355

I would recommend one of the old Competition Models (Sal Taibi) kits of the B-70 as a test plane. A very quick build and a surprisingly good flyer. A pusher 6-3 or 6-4 should be easy enough to find.   Steve

Hello Larry,
Maybe an1/2A starter, with the proviso that you check that the engine isn't flooded. If it doesn't start at once, don't grind away with the starter. The little PAW isn't designed for a starter, all of mine DON'T have a steel washer behind the prop driver, so you grind Aluminium alloy on Aluminium alloy. Not good!
Where can I get a 1/2 A starter that doesn't cost the earth? Last time I looked I could only find one (SIG?) and that was over $80, too much for me. It would be useful on the small APC props, which are finger slicers even when sanded down!

Thanks,

Andrew.

P.S. I have a couple of lightweight stunters called the Cheshire Kitten. With the PAW 0.55 up front it will perform wingovers and most round maneuvers. vertical and horizontal eights and even a cloverleaf if you practice, build light and it goes well even on carpet thread!

I'm a fan of the PAW diesels.  I don't have the PAW 55, but I'm flying a replica Elfin 1.8 reduced down to 0.020 cuin. size.  It hauls around this "Tiny Fry" on 40' lines, and is still too fast.  I'll have to use longer lines.
