If you're using any engine larger than the originally-intended .60/.61-size two-stroke engine, then prop clearance can be a difficulty. Originally, the model used an 11- or 12-inch propeller. When it was designed, four-stroke engines were not very common. Later, it was re-done to show some four-stroke installations, but they weren't as large as the 1.00 you're thinking of installing. I guess you'll have to make sure to do all takeoffs and landings in the 3-point configuration.

The only fix I can think of for that is to use fuse mounted aluminum gear. I did that on mine, works great.

Well, the issue I am facing is that with either the .82 or the 1.00 (the plans show a .91 4strk-believe it is an Enya) they both swing a prop within an inch of each other. I could use the .82 and swing a 13x8 or 13x10 (if there is such a pitch) and that would be a little better but not a huge difference. Actually, just remembered I measuered the fuse sides/formers for the 1.00 so I guess thats where I am headed. Perhaps a 3 bladed prop???

I want to keep the gear in the wing to stick with the "stock built" aspect though I am sure that would be an easy fix having it attatch to the fuse.

Iused a 13" prop on mine with a .75-AX. Had no clearnace issues. You could always go up in tire size or maybe even bend up some slightly longer gear legs.

My buddy runs a 13x11 apc on his Saito 1.00 and it's the perfect prop for that engine (vs the 14x10, 13x10, etc). That's what I'd run if I were you.

I bet that would give interesting top speed!! What airframe does he run it on? I also saw a 13.5 x10 APC that also might be an option.

I went with the 40 size with a few minor modifications. It has a pair of OS 55s. I hope for a maiden flight this weekend.

Wow that's a beautiful covering job.

I'm going to start my SS60 kit later this summer, and I'm thinking about installing a Saito .90TS twin. I think the twin cylinder heads will flow nicely into the contours of the fuselage, but I may need to come up with a custom cowl.

KEEP A .60 ENGINE.

The engines 20 years ago where not as powerfull as today.

The rudder lacks authority as told before.

cheers,

Juan

I am going with the Saito 1.00 and an APC 13x10 prop with 30% nitro....should not lack in performance!![X(] With the thick slab tail etc. I was going to need more nose weight than the Saito .82 had so it makes sense to move to the 1.00. Fuse is 90% done now just have to finish up the wing mounting, nose block and sand. I will be giving Monokote another try on this bird. I switched over entirely to Ultracote a few years ago and swore I'd never use the "new" Mono again since it was such a major PITA!! I want to use the windex method for my striping and also use the matching Lusterkote paint for the pants-hopefully I will not regret the "cote" decision. Colors will be Yellow base with red striping (like on the box) outlined with blue striping tape. I think it will look quite nice.....I'll try and get a few pics when its done....

I put in dual aileron servos...never have been much on a single one. This has been a very fun (though short) build. Looking forward to seeing it streak across the sky!!

Just be aware that the 13x10 apc might not be enough prop for you Saito 1.00. My buddies turns the 13x10 @ over 9900 RPM on 15% fuel... The 13x11 apc was the proper prop for it instead @ around 9300-9400.

aa1a,

I built a SS60 into a twin useing OS55AX engines. They pull it around at about 90 mph. Lands a little fast. Flys good on one engine, but mine runs out of rudder at about half throttle even with one inch added to the front of the rudder. When landing on one engine its best to keep a little speed. You don't what to get low and slow onb one engine.

This is what happened to mine when the right engine quit. I got low and slow and not enough rudder at full power. The right engine quit when the rear part of the muffler come off. It took about three weeks two fix it.

Default RE: Super Sportster 60

Greetings. Just came across this thread. I am finishing up a SS 60 this week. Have had it for about 2 years and decided to get it done. Powering with an older O.S. 61 SF abc that I have had new in the box for the last 24 years?? Never been run and brand new. Should be enough power although a new OS 75 AX would be ideal for this model.  Several years ago I built the SS40 and the SS40 Bipe powered by a Rossi 40. WOW!! Those were fun!! I'll try to upload a few pics, along with a few from my current build.  All have been the standard taildragger. I add basswood ribs (full size) to each of the existing balsa ribs (1 on each side of the stock rib), along with the factory doublers which really reinforces the gear setup. This holds up extremely well with very little added weight. I just like the look of the stock gear better.  Love these planes! Can't wait to fly the 60 as good as my 40 sizes flew. The bipe was awesome but a bit squirrel(ly).  The Rossi 40 was one of my favorite engines, although a bit loud. Strong, reliable, easy to run. Wish I had a Rossi 60 engine!

Two long 2 56 push rods ? No way.  I cut out for servos half way back the fuse. And drilled holes all over tail . And pushed La 65 to front of mount. If it still comes out tail heavy , I will install longer mount .

Belly pan is made removable  .( No donut behind spinner)

2 Aileron servos out on wing is so easy to do.

Yes, I know this my not look as nice, But I like to get to my servos/ batt./ fuel system and this makes engine mounting easy.

I am not good at covering . Wish I Knew how you guys cover like that.

I built my SS a couple of years ago. I scratch build mine but the plans were a great start. First of all I added a little more area to the rudder and made it a pull/pull system. The landing gear is mounted on the fuse and works very well. I will admit the the wing mounted gear looks great also. I formed the turtle deck and front cowl over forms for a lighter body. I tend to over power my airplanes a little and this one is done with a Saito 100 GK. Really moves out when I want it to. Also the alerons are larger with servos for each aleron. Other than those mods it is the same form SS60. I attached a couple of images of it.

Thanks Buzz. I used all Monokote and only painted the wheel pants. The day-glo green was more difficult to work with. It doesn't shrink as well as the regular colors, and will bubble easily. It's been about 18 years since I last built a plane, so my covering skills started off a bit rusty. I couldn't tell if Monokote was more difficult than it was 18 years ago, or if it was me. Still turned out nice though, I thought. Just starting a Balsa USA1/4 scale Sopwith Pup which I will probably use Solartex. I hear it's also easier to work with and comes in good WWI colors and texture.

Thanks again.

Buzz, I used the attached image that I found as a scheme to follow. I may or may not add some of the stars and other detail. It looks pretty clean as is.
