So sorry to read of Bill's passing. Although I never knew Bill, I did benefit from him and his work because, like many others, I had a number of Merco engines in the past. RIP Bill, enjoy that big Flying Field and Thank You.

Sad to hear of Bill's passing, though he appears to have had a fine innings which many would envy. Another chapter of model engineering now in the history books.

People sometimes disparage Merco engines, but they were leaders when they first appeared and something for Bill to be proud of. As often seems to be the way with British innovations, they did not ultimately keep pace with development enough compared to the Japanese and German offerings. The 61 in particular will still pull an appropriate model around the sky with decent vigour though.

I believe when Gerald Smith became "old " his friend John Scott Scott of Skylon fame helped Gerald finish off his final batch of engines ,

John was a fine engineer and had a workshop to be envied . Now he did convert many Mercos as well as many other makes to petrol, and worked with ED in the early days .May be one of his ????

cheers

Sorry to hear of the passing of another of the "old guard". Not many left now.

I had a Merco 35 back in the late 60s. It was a good engine, unlike the .49 that I bought a year or two later, which was a disaster! Ran fine on the ground, but would die without warning in the air - usually on take-off. Model went into the hedge many times as a result before I got shot of it. None of the local experts managed to sort it.

Bought Webra 61 as a replacement (late 67 or early 68), and it flew just fine in the same model, with the same plumbing!

Its still flying my classic aerobatic model today!

I had a Merco 61 that did the same thing . I cost me a nice model Spitfire . I tried everything with that engine to no avail . I decided it was just scared of hieghtssmiley . I converted it to a water cooled engine as they are excellent boat engines .

I bought 2 Merco 61s on a charity stand at a dog show for a tenner the pair. Took 'em apart and there appears to be nothing wrong with them. I was always jealous of Merco owners as a kid.

Hundreds if not thousands were sold (.61 size) to the Army, and fitted in models that were used as targets. Whist serviing BAOR, I used to book the team that used to fly them, and scrounge as many bits of them as I could. (11 x 7 blue props, skyleader gear, plugs etc. etc.). In the event of them being shot down, I had to sign them written off. More searching in the woods until the bits were found. Never had so many Mercos in my life!.

I have to say my experience of Merco engines was mixed, I had a 35 RC which was great and a twin plug .61 that was rubbish. I was so pleased when HP engines appeared.

Italian Super Tigre 51 had those markings Adam

Are you certain it is Merco ?

Hi Adam

You can’t find anything because I think you will find it is a Super Tigre engine not a Merco unfortunately, although good in their own right you should find something under ST.

There's no such thing as a "Merco 51"!

Just Google "Super Tigre Como 51" and you'll get a load of hits.

Thanks for the info- it literally has “Merco” on one side of the case and .51 on the other! I don’t know much about the heritage of engines- are you able to explain why it’s not a merco?! Many thanks as I have no leads!

Good morning,

The she’s elves have scrubbed the Merco off! A real head scratcher. I acquired a few engines so perhaps I’m muddling them together.The engine in question is a como 51. Which I now think is a thunder tiger varie t?

looks pretty clean. Thanks

The best advice would be to stop "just thinking".

The Como 51 was an engine produced by Super Tigre around 1980. End of story.

Confused thinking around random other names that you may know is never going to change that.

Like I said, Google "Super Tigre Como 51". Then click on "images" and you'll get a page full of images, some of which will be of your engine.

Adam, I think that Brian, "Broken English," is right. I suspect that this is your engine isn't it?

super tigre como 51.jpg

Super Tigre were an Italian make famous for their high performance two-strokes. After the original owner retired they were bought up by, I believe, an American and production went to China but they went out of business because the demand for glow engines, especially two strokes, fell away with modellers increasingly powering small models with electric motors and large ones with petrol engines.

You are also confusing Italian Super Tigre engines with Taiwanese Thunder Tiger engines! Thunder Tiger have also gone out of production but both marques are still good quality engines and worth bothering with. I have a Super Tigre 40 ear marked for a sports aerobatic model and Thunder Tiger four strokes in a WOT 4 and a Senior Telemaster.

Aeromodelling is full of confusing nomenclature. I wish I had £100 for every time someone has confused a Keil Kraft Junior 60 with a Keil Kraft Super 60! wink
