Status: offline 		I bought a SS 90-1.20 at a hobby show in Feb. I got it with a OS 1.20 (old school four Stroke) it had no compression. I took the valve cover off and it had fuel gunked up in it. I cleaned it out with Alcohol and the stuck valve started working again. The Compression magically came back. I got the whole schmue for 60.00 I've ripped off all the painted covering and I'm in the process of recovering it now. I'm new to RC after 10yrs of layoff. I have a trainer and have my feet kinda back under me.

The real bummer is I knocked the motor off the bench and broke the carb body. anyone have a Carb for the OLD FS120 O.S.? If it works out that the motor is shot, I'm thinking of using a YS engine. My question is the motor mount is aluminum and is drilled for the OS FS120, will the YS 1.20, 1.40, 1.60 use the same mounting holes or are they different? Will the rails be too wide/narrow for the YS engine? If so I would not hassle with changing the engine mount out due to the way it is in the plane currently.

I really am looking forward to flying it. It is going to be my second plane. I plan on having an experienced pilot on a buddy box with me on the first flight to make sure all goes well.

Status: offline 		If Tower can't get you a carb, check the size of the Magnum 120 carb. It might fit. Call Conley and see it he can give you a Perry carb for it. (Google Perry carburetors). If nothing else works try Randy at K&B. He collects old engine parts.

Jim

Oh yeah, and don't run caster oil in that engine. You have already seen what that will do to a four-stroke.

Just got my brand new SS 40 kit from tower. And the 60 size should be coming next month. Check with Tower for your GP Super Sportster needs!

Now where's my CA at.........

Happy camper here!

Status: offline 		I recived my Sportster .60 kit from Tower today! It looks pretty much the same as the one I built 10 years ago except that the box is white instead of blue. The quality of materials is typical GP, the wood is a little hard and fuzzy but not bad. I think this might be my next project after I finish my current GMP Sunbird build. I have an OS .91 FS that needs a home!!

Status: offline 		My 2 Super Sportster 90/120's I built from kit, my Super Sportster 40 ARF, and my new Super Sportster Giant ARF. They all are great flyers, and I will always have at least one Super Sportster in the fleet.

Status: offline 		Hi I have a 40 Mk II ARF still in the box, and have ordered a Saito 62 four stroke.
I have and intended to run a Super Tigre GS40, but would prefer the cleaner and better sounding four stroke.
So much that I fly smaller electric planes and E Gliders, rather than the messy GS40.

I think it's a nice plane and would look better with the four stroke. I went for the Saito as the recommended OS 52 is now discontinued, and the Saito is better valve in New Zealand, from RCBandit.co.nz.

My question is about prop size and ground clearance. Fly from rough grass strips will be using the recommended larger wheels without wheel spats. The Saito 62 recommended prop range is 11x7-13x7. If I went to 12 inch will I leave enough ground clearance? Not after too much prop, as I don't want to hover it 3D style. Just looking for clean smooth flying sports plane. Perhaps a 11x7 will be enough?
