Bag o' junk

I was handed a grocery' bag of "junk", the other day.

OS max 40H
Enya 19
Enya 35
Fox 40
Profi 40
Merco 61


Merco is missing the needle valve... and I'm short a coupla prop nuts.

Other than that, the haul seems to be quite complete and functional.

Am sitting here, wallowing in nostalgia. 'Specially for the Merco, and the Enya 35.

How does the Profi .40 run. That's probably the gem in the bunch.

Dunno ... haven't run any of 'em. Seems OK, though.

I had a .60, years ago. Bit of a beast.

Is that the Hornlein Profi, or the Ukrainian Profi?

Hornlein, afaik.

Gold-coloured crankcase.

Moulded plastic fore-part, which carries the carb.

Didn't know that there was another manufacturer, called Profi. Looks like this one ...

The Enya 19 takes me back, it was my first 'big' glow engine before moving up to the heady heights of Merco 35s and the like. What would that be, early 70s?

Could be 70s.

There's a few old servos in the bag ... amongst them, MRC servos and 27 Mhz receivers.

One of the servos has a price on it ... 19.50. So, it's post-decimalisation. But, quite a costly item, for its day.

Another servo has a label on it, stating that the owner had replaced the gearing in 1983.

There's also an old OS marketing leaflet, about A2 -sized. Amongst the items for sale, are the old open-rocker FS-60 and a bunch of live-steam locomotives. ... and those dreadful Wankel engines.

I didn't know that OS apparently had their own-brand of RC equipment. There's a range of outfits, called Cougar and Arrow.

Ukrainian profis are very exquisite fourstrokes, so it would be a real find if it was one of those....

I have a Hornlein Profi (also found in a box of trash) but unfortunately mine is REALLY trashed by its previous owner, and will never run again...

I ran Enya 35's and 45's and found that they ran really hot. Otherwise, great engines.

Might have been too lean.

Or too much nitro. Try them again on 5% and see what they do.

I ran some of those engines, the other day.

OS 40 worked straight off.


Merco 61 was missing a needle valve ... but, there was a brand new carby in the bag. So, with that fitted, the engine ran great.

Fox .40 needed a bit fettling. Bit of damage to the piston crown. Not much, but enough to pinch the piston ring and prevent it from expanding properly. Sorted that. Engine runs great.

Enya 35 ... prolly the best of the bunch, once I got it running. Turns out that someone had fitted the incorrect needle valve. So, even with the needle screwed right in, fuel was still pouring into the engine. Luckily, I had a suitable needle in my spares box.

The Profi is a duffer. Absent its piston ring. Might try to source a replacement.

The Enya 19 needs some attention. It's held together with an assortment of screws ... every one different. Well, it's not really held together at all, since the front assembly rocks about, making a gas seal impossible. Hoping that a bit of TLC will bring that engine back to life.


Now thinking about retro airframes ... maybe something for the Enya 35 or OS 40.

AFAIK, they haven't been used since the 80s. It's remarkable that all the bearings seem to be perfectly serviceable. Castor oil? There's plenty of evidence of its use on these engines.
