Outrunners would need to be geared anyway - these things presumably swing big props slow.

The spirit of the age would be a sparker. And no radio. Covered in silk, made of split cane...how far do you want to go?

I simply like light slow models and whatever it takes to get them in the air

Ian, what is the original spark motor specified on the plans? If it was a .60 size then your .52 has many times more horsepower than the original. Also, the original ignition powered model had to carry the extra weight of an ignition coil, battery, cutoff timer, etc. so with R/C gear yours would probably weigh comparably. The .52 would therefore fly the plane with much more authority than the original.

The plans show a "Dennymite" and says "any diesel or petrol engine 10-15cc"
I agree that my 52FS wouldn't have a problem with this one and I think it's the way I'll go. Next choice: Free flight or RC!

build it RC and don't touch the sticks unless it looks like flying away ?

Vintage,

That's two votes for RC as my wife said the same thing as you.

Freeflight With A Big Slow Revving Sparkie Up Front!!

I Have An Ohlsson 60 And It Runs With The Slowest Sweetest Tickover You Have Ever Heard!!

Does it look something like this?

What size prop do you use on your Ohlsson?

certainly does, i dont have it in a model but it runs on a 14x6 wooden prop.

Gerald,

You wouldn't mind if I borrowed that engine would you

It would look really good - I'd even put your name on the side of the cowl as an official sponsor

i wouldnt lend it out, but its for sale. rebuilt using brand new parts, complete with plug and test run on the bench £100

It should be interesting when they arrive.

I bid on that plan, no time to build yet, too many other projects on the go.
The KK Falcon was free flight, I wanted to establish when it was available from KK. I looked at some old KK catalogues (hard to date but Two Shillings and Sixpence) and though they had early digital propo gear they also listed rubber driven escapements and the Super Sixty. The Falcon had already fallen from the list. My recollection was that they were available in the 50s and were free flight.As to power, that depends on what you want to do with the model. The Junior Sixty was definately underpowered with an ED 2cc but a Competition Special was considered just enough. An ED Racer was plenty powerful enough. We flew largely when it was windless, early am or just before dusk, that way it was calm. I would think that a modern .40 Glow would be plenty powerful for a KK Falcon. I know however that modern fliers would want to fit a .60 Glow.

I think I have an Aeromodeller from 1947 that shows it - I'll check again though.

Ian, I have just bought a Falcon on E-bay. I can remember the Falcon indicated on an early keil kraft models list I had when I was about 12 years old. (1959) but it was not available at that time. There was also another large model indicated but I cannot remember its name. it was bigger than the Southerner or Junior 60

The Falcon which is nylon covered and weighs 7lb 7oz without engine or radio fitted. it will probably chug around the sky much the same as the Junior 60 is my guess

I have a OS 60 open rocker in mine with loads of power. The 52 would be just as powerful as the old 60 with even more rpm's. The fuse of the Falcon is kind of neat being round and the stab and main wing just dwarf the fuselage. Excellent flyer and must have a four stroke up front have fun with it....Bill

Hi Ian,
Have you built the falcon yet? I used to be the fetcher for the local model shop owner's falcon back in the mid 50s, furthest fetch was about 5 miles out.
In 2003 I retired and a friend built me the ben buckle kit covered with solartex and with a laser 70 four stroke up front. This gives the model a very steep climb and I had to use about 8 degrees of down thrust to sort it.
It flies beautifully and this year is the only year since then that I haven't flown it, reason being I have a Southerner Major that I've re-engined with a saito 62 and I just love that shape.
I also have a junior 60 with an os 26 fs, a Black Magic with another 26, a windy aint it ( a plan built model, shoulder winged) with another 26 that I haven't flown since putting the engine in.
I'll see if I can get a few pictures to upload.
