RC IC Engines, you've probably never heard of.

I bet there are many IC engines, that most would never have heard of. Even copies of OS/SC types, or only available in some countries.

I'm going to kick off with the most famous of the "unknowns" - many of you would have heard of "Mutunuc".

There was a 40, 61,65 and 80, and so far only have 2 or three of the 61's and 65. two are in models, three are new in boxes.

I have 300 plus engines spare on the shelf and 200 in a random box, just used 2 up this week on new builds, anyway.

Ok next one, who has heard of "G" engines? Looks like a OS 46 AX, and runs well. Bought it in a model and the other OS 46 was £5 including the model, but needed clean and bearings, the" G" engine runs really well and flew it last year.

Presumably some of these are out of the same Chinese or other Far-Eastern factory, and 'Badge Engineered' to suit the distributor.
As I understand it SC, ASP and Magnum were all from the same source, Sanye. SC were sold via Perkins to the UK and Commonwealth countries, ASP were initially sold by Indy R/C in the USA and later by Horizon.

Other 'makes' you could include are:

Bluebird, distributed by MFA

Flash or FLH (around the time Thunder Tiger first arrived on these shores)


J'EN - Just Engines 'own brand'

Were Mutunuc ever get sold in the UK officially? The ones I have were £20 in a plastic bag 'pig in a poke' from SMC at Sandown.

Moving away from the Chinese and Taiwanese engines, how about these three from Italy?

Cipolla - various sizes in the 1970s & 80s, they still making model car engines by the looks of it.

Kosmik sold by Micromold (as far as I can recall).

Como - Como was initially a Super Tigre engine built for control line aerobatics (stunt) but then sold with an R/C carb. Unusally for a stunt engine it had Schneurle porting.

How about Master Engines from Russia? Master Motors - Russia

Meteor Engines in 40 & 60 sizes from her in the UK in the mid to late 1970s

Ueda Engines from Japan in the 1960s and 70s

Phil Kraft, the R/C manufacturer and designer of the Super-Fli, Bar-Fli and Ugly Stick in the USA did his own Kraft 61.

I assume we are only doing two stroke glow engines, otherwise the list starts getting quite long with the various four strokes from Magnum (UK), Powermax, Kalt, Kavan and so on; not to mention all the two stroke weedwacker and chainsaw petrol engine conversions (Quadra, Tartan, Fox (from Italy) US Engines etc.).

A few years back, I had an "AirSupply" .40 engine in a helicopter. I believe it was made in Japan.

I tried it on my usual 16% nitro heli fuel, and it didn't like it at all! Switched to straight (no nitro), and it ran like a turbine! Unusual, as Japanese engines usually like their nitro....!

I once had a Japanese HGK 15. Nice looking & seemed well made but it would only run for a couple of minutes before overheating, losing revs then dying. Tried running for in ages on a variety of props & fuel combos to no avail. The construction was interesting, cylinder was thick aluminium mono-bloc construction with the fins cast on the outside with a chrome plated bore - AAC.
Other engines in the range were said to be good reliable performers but the 15 was a dog.
