I was feeling a bit guilty at having hi-jacked the Ramrod 250 thread with all the talk of Nostalgia FAI, so I thought I’d start a separate discussion.
Here’s an Aeromodeller cover from ’66 with one of those glorious elliptical models that were so evocative of the era.
Joe Savini and ‘Faital’ – sometimes I thought that wasn’t the best name for a model.

Beautiful. Just beautiful. And that looks like a Dixilander laying upside down. I feel I may have said that before somewhere, as we felt it may not be?????
Hi Gos,
Sorry to be using the same pics over and over, and to try and stop the discussion centreing on the upside model in the background which I am fairly certain is neither FAI nor a Dixielander – I will try snap some pics of the nearly finished Night Train this weekend!John
Some pics of old style FAI power models.
Night Train and 60’s Slick Stick taking shape.
Night Train fuselage – genuine Roy Collins Night Train pan, too.
This is the engine for the 60’s Slick Stick – Buskell homebuilt, to be used with a ED tuned pipe – as used in the 1968 UK Team Trials – 6th place – and a long story about why a team place was missed.
….and lastly the (in) famous Buskell Mk2 ‘Pump’ engine.
With Primary, or Crankcase supercharger.
As used in the ’62 Team Trials – 5th place finish – turns a 10″ prop.
That ‘charged engine is without doubt ‘some effort’.
Tell us more about it’s insides please.One Hell of a huge hole in the rear of the first one. Too thirsty for team race I guess? LOL.
The Pump Engine;
There is a 2nd piston in the blank, lower cylinder. The 2 pistons move in opposite directions, so that the pumping effect within the crankcase is vastly increased over a normal engine. When the pistons are moving up their respective bores (away from the crankshaft) more fuel/air is pulled into the case, and when they descend (toward the crank) more fuel/air can be pumped up the transfers. There is no means to move fuel up into the pumping cylinder (no transfers, no exhaust, no combustion chamber)
The firing cylinder has twin opposed porting (Cox style), and the piston has a domed crown.The engine in the picture needed quite a bit of restoration (many thanks to Derek Collin of f/f scale fame for his assistance). It’s in running order, but is very hard to start. Although I was very young when Dad was using it, I remember it being hard to start then, too. Basically it’s over compressed, and pre-ignites – putting 50% nitro into it, one can get bursts, which confirms the over-compressed diagnosis.
There’s a diesel version, too – the Mk.1.
JohnWhat a huge effort. You say it’s hard to start. Finger starting or electric?
I hope you don’t mind John, but I passed the pic onto Ron Churnic of Motor Boys. These guys live engines, and Ron, who lives not far from here has a monthly newletter.
He was most interested and did not know of it. He may contact you via here I guess.I’m an old fashioned guy, and prefer to hand start my engines. The only time I got into electric start was when I was using folding props on F1C’s.
Actually I’m not sure what an electric starter would do with the old ED style prop driver/spinner – it would just undo the spinner, wouldn’t it?
I look forward to hearing from Mr. Churnic; I just love talking about these engines, and the work my Dad and Mike Gaster did together.
Johnp.s. Check DKW motorbikes – the inspiration for the Pump engines.
There’s no way I would put the electric finger on that nut set up either, but I am sure a suitable spinner would do the trick to get it rotating.
How about picking up or turning up a really nice aluminium one, as an ‘after market’ thing? I start most things with the finger, but sometimes do use the electric. Rossi’s start fast with either.Yeah, I know of the supercharged DKW’s, as I have been a bit of a 2 stroke ‘bike nut, but I will pull it up and take a look. They were the famous racers from memory? Thanks for that link.
I will PM Ron’s email address, as I know he is interested, and you can ‘touch base’ with him. Have him give you the info on his monthly engine newletter too. It’s all free and on the web.

John, I see you have a Quest rubber powered ROG there in the picture, no shop is complete without one! Those fly great, I am using several to train my twin 3 year old boys to fly. The built in wash-in/wash out assures a proper flight panttern, I fix breaks on the foam with Scotch tape.
