What a beautifull airfield, you wake up in your camper, step outside, and you see a full size Cri-Cri (French voor cricket) rolling upside-down 3 metres above the grass. Full size Ónd model flying is still plenty in France. Because French do like airplanes.

I have aquirred a pair of reasonably cared for OS .60 FS of the old style exposed rockers type. Are there operationg instructions avaialbe on-line? And can these be mounted inverted and/or side mounted for scale applications without worry?

Please excuse my ignorance, as i've never operated any 4 stroke types.

And TIA!

thank you very much, Carlo!

I would like to mount one of my .60 FS in a very light 1/4 scale Aeronca (96") and use it in a side mount or inverted. Any horror stories applicable to such an installation?

G WILLIE, is this true ?
"The Fox .29R (ashtray intake) is a problem engine in that Fox never did learn how to taper and fit pistons for the application and very few of them will run really good. Also Fox made a lot of different .29R and .29X engines. The only one suitable is the one with a plain bearing and a round intake tube; it sort of resembles a standard (Fox 35) stunt engine. Most of these had a number and an R stamped on the engine somewhere". (Quote from - http://www.modelresearchlabs.com/C700inchSpacer.doc ) BOB

I must confess to a liking for Johnson engines, and have just purchased the 1962 36 R/C shown below. This is a "big case" Johnson, and when they first appeared in 1960 they had only one real weakness, and that was that the 2 long headbolts directly above the exhaust stack screwed into the same thickness of metal as the stack itself. Thus, those 2 bolts would easily strip their threads if only moderate force was used on the screwdriver. Later 1961 models had a little extra metal added to those 2 threaded holes, in the form of a "dimple" which extended down from the interior of the stack at each hole. Many used "big case" Johnson's will have a nut on the end of those 2 head bolts to further strengthen the set-up. Be aware that if you buy one of the "Sport Special" Johnson's with the shortened venturi, your engine has probably been made up from originally rejected "2nd grade" parts. The engine test below from American Modeler Feb. 1962. Further Johnson info at -

Photo below right shows a Combat Special on the left, a Stunt Supreme in the centre, and a "Small Case" 35 Sport on the right. The photo at the bottom shows the first model with the 2 head bolts held merely by the thickness of the exhaust stack (look closely). BOB

Whilst I find these huge models quite fascinating, I can't help wondering why anyone would build such a large model - why not go that little bit further and build something you can actually get into and fly yourself ? Which brings me to my next question - who will be the first idiot to put a child on board for a joy flight ? Shown below would be an ideal "huge" model, the beautiful Lockheed Altair. This is the last photo taken of Sir Charles Kingsford Smith (in the centre, with his mechanic/co-pilot Tommy Pethybridge on the left) at London's Croydon airport in October 1935, just prior to them both disappearing on their flight to Australia. The mechanic is topping up the oil tank for the Pratt & Whitney Wasp.

Here we have the latest in VTO aircraft, but I'm not sure where the pilot sits.

I really feel that the OS 60or will not be enough power for your model. As I'm sure you know weight is only one thing to consider, drag is another.
If you had a really long runway you might get off but any wind at all will make that model very interesting to fly.
A newer more powerful 60 two stroke would do it but I would lean towards a 90 or 91 four stroke.
Just my opinion of course and good luck with what ever your choice.

Bill

How light is the plane? If it is like a Sig Senior Kadet (the kit, the one you have to build, not the ARF thing), then yes it would work. I flew a .60FS in my Senior Kadet for a very long time. It had too much power for the plane, but I had a throttle so i would tool around at 1/2 throttle or less even.

But if your Aeronca is heavier besides being bigger, it may be a problem, hard to say though for sure.

A side mount installation should pose no problem. Inverted is OK, but then the rocker arms are exposed and on the bottom where it gets dirty and gritty from the dirt being kicked up by the prop on the ground. Inverted also means the fuel tank location needs to be really close to ideal as well.

Maynard Hill had his TAM 5 record setting distance plane setup with a modified OS .60FS engine and it was side mounted. Oops maybe it was a OS .61FS engine he used. I am not sure now.

So I would suggest side mounting the engine.
But William3590 has a point, a nice .91 size engine would be much better.

I owned and operated Aeronca KCA No.19 (of 56). It had a c-50 with up stacks, no carb heat, and no stearable tail wheel. It was built in 1938 and operated ln Standard Category, which meant it was a real aircraft, but just barely with only 50 HP.

An old FFer and have long felt most R/C models are way overpowered, largley because they are usually overbuilt. I don't fly in strong wind conditions and plan to fly very realistically. S-L-O-W-L-Y and no vertical performnce what-so-ever, just like the real thing.

Hi Charlie. I bet that youll not find any problems. I saw various scale J-3 flying with four stroke inverted and sideways engines without any problems.
Please inform us the progress you made in flying the Aeronca or any else.
All the best

Believe there is a pic of my Sig Sr Kadet in a previous page, in fact that model was SO light that this OS FS60 was indeed overpowering, only needed half gas on the throttle stick. I wished I never sold that plane earl, the most perfect trainer ever. I do have the prefab version in the attic, finished in red see-trough and black oracover. Chinese prefab.

I still have my big Sig Kadet. It has been powered by electric motors and by glow power off and on over the years. I pulled it out of storage recently to refurbish it some and try a RC Drone .29 Diesel engine in it for a change. I love how one can tool around for a relaxing day at the flying field, just to have some fun, no stress etc. The original plans called for a .29 to .36 two stroke glow engine for power. I think it is more like a glider than a powered airplane.
