SV: SV: Diesel Conversions

Honestly, I started with this hobby late august this year, and so far I have
a couple of glow engines, a couple of planes, an order for my first two
electric planes, so I guess it hasn't been much time to collect vintage
parts, still I have a diesel, and a good idea how to start it adjusting the
compression due to engine temperature and get it in the air, and belive me,
I will get it in the air.

Generally I'm intrested in all technology from the past, tube radios, old
steam engines, and in the summer I use to run an old crude oil two stroke
engine for a local museum, so I guess I have quite a bit of understanding of
old engines, just not model engines....

Other than that, you are right, few newcomers to the hobby takes time to
read up on the history, or even talk to those who can tell, I always enjoy
talking to the "old farts" that has been in the hobby for a long time, it's
just that the flying season is over here (numb thumbs due to -30C) and I
dont get to see my flying buddys in a few months.
The Frog was previously my neighbours, I got it for free a month ago, still
in the box probably just run in and never used....

If it was like my frog 80, not even run in. :-(
Never would stay running long enough to run in :-(

Perhaps if the guy at the model shop had told me it needed an hour of
running first....

Re: SV: SV: Diesel Conversions

Before PAW, the English, nor the Americans simply knew not how to make good
diesels. I am speaking of the fifties here.
I started out with English engines, but advanced in the hobby only after I
switched to German Taifun's and Austrian Webras
These were wonderful running engines, which still start on the first flip
whenever I want to demo.
Lately, when with Brian Felice, I ran a PAW 21 , new and not run in yet,
which also quite impressed me in it's running culture, though definately not
a first flip starter. This was probably due to the seasoned fuel that Brian
had available.

In teh 60's the Mills 75 was a good staring diesel - I had a worn out
onve once. However the porting was fairly dire, and the power not high.

I think the real breakthrough came when people started making them on
precision machinery - the designs weren't bad, but teh production
quality was awful. You got good ones and bad ones as I recall.

I never could afford one of those :-( Fortunately there were lots of
kids who got other engines that they got bored with or couldn't start -
after the Frog 80 I could start ANYTHING. I ended upo with a selection
of cox glo engines, a frog 100 or 150 - forget which - some ED something
or other, and a PAW 19. Plus a crap frog 80 and a DC bantam neither of
which ever powered anything successfully.

The ones that stand out as being 'modern' in the sense that they were
powerful and started well were the coxes and the PAW. Oliver Tigre was
another name that springs to mind, but I never had one.

I could probably get away with flying a small diesel where I fly - they
aren't too noisy. PAW would definitely be my first choice.

Really? That would seem to be a bit mad, as it also makes the main
needle valve 'unpredictable'

I believe you though. Its a long time since I stared into the ports of a
diesel engine :-)

Re: SV: SV: Diesel Conversions

All diesels in my collection (about 15) have this feature, except the PAW.
A diesel I converted to glow also ran well, albeit exceedingly loud. I do
not think that the
lower piston skirt opening the exhaust port into the crankcase hurts top
end, just the ability to throttle well.

Well you live and learn. Might work well with tuned pipes then - use the
back pulse to pressurise the crankcase...

Re: SV: SV: Diesel Conversions

I have an OK Cub .049 diesel that starts with a few flips and sometimes on
the first flip. I think the only thing limiting perfect first flip starts is
me.

Re: SV: SV: Diesel Conversions

Good old sub piston induction, a left over from the side port days, is the
culprit.
