You can likely order them through Great Planes. They are also available through either Model Airplane News or RCM, can't remember which one. I'm not sure if the GP kit version and the magazine plans version are identical or not.

The plans for the Great Planes kit can be purchased for $11.19. http://greatplanes.com/parts/gpma0210pl.html
Although this is not the 90/120 sized plane.

The plans for the 90/120 Super Sporster are available on RCM for $19.50. This price also includes the construction article.

I wonder why GP shows plans for the .40 and .60 kit but not the .90? I had the plans and wood for the .90/1.20 and planned to built it but never got around to it. I ended up giving the stuff away.

Ken, these plans from rcmplans, do they include drawings of all the ribs, formers, ect... so a laser cutter could kit it?

Yes, Plans from RCM include everything that is needed to build the plane. Every part that needs to be cut will be included on the plans.

When Iget plans for planes the first thing Ido is take them and get them copied and put the original plans away for safe storage. Imake two copies of the plans, one to cut with and one to build on. The important thing here is to verify that they copies are the same size as the original. Simply lay the copy on top of the original to check this out.

Thanks Ken. Next question. Who are good kit cutters at reasonable prices?

ChuckW

I don't have a good specific answer on the laser cutting service but if I recall the article comes with a pretty complete materials list. This makes it easy to go to a place like Lone Star Balsa or similar and order all of the necessary wood. there aren't a lot of complicated shapes on this airplane. You could cut them all on a scroll saw fairly easily. Of course nice laser cut pieces sure do save time and make life easier.

Could be because the 90/120 is so different. The 40-60 and even the 20 are all built about the same. The 90/120 is the same in the wing, but the tail feathers and both decks are totally different. I could build two 60s in the time it takes to build a 90/120.

True but they kitted the .90/1.20 and they have the manual online just no parts or plans. Must not be popular enough to keep around or something.

I have gotten to where I can build the SS 90/120 in my sleep. I have built 2 from kit and am currently scratch building one from plans. The plans do have the rib templates and are good to scratch build from or from kit. If there was no other way to get the plans and nobody offered them.. I would be happy to help out. However...RCM does have the plan available for purchase and they would appreciate the business I am sure. I would be happy to answer any questions or take some measurements if needed. Do your plans have the updated sheet talking about static balancing? The 90/120's are notorious for shedding the tail feathers if not properly setup. I also strongly suggest guide wires on this particular plane as well as making sure good hardware is used and the hinge lines are sealed.

Who cut the 2 kits for you and were you pleased with the quality/price? Were you happy with the performance?

Mine were both Great Planes kits new in the box. The one I am currently building.....I cut all my own parts using some templates I made and a band saw.

My first SS 90/120 was first powered by a Saito 100. It flew it, but this is not enough engine for it. I would definately say a 120 4 stroke is the minimum and a 150 would probably be much better suited to this plane. I then put a Super Tigre 90 on it, and although the Plane flew very nice....the Super Tigre 90 was also pretty marginal on this particular airframe, but I still enjoyed flying the Plane and it flew basic manuevers just fine, but very limited verticle.

My 2nd SS 90/120 I had an SK 90 2 stroke on it. About the same as the Super Tigre 90 except that the SK 90 would swing a little larger prop and thus had a bit less speed, but did have a bit more climbing power. My conclusion is that something like the Super Tigre 2300 would probably be a better match or maybe something like an SK 1.10 or 1.30 2 stroke for spirited performance.

The one I am currently scratch building is being modified to use a Ryobi 31cc gasser. The Ryobi's are heavy and a bit down on power...so in most cases I wouldn't reccomend one for a sport plane, but I like messing with them and the SS 90/120 has good lift and will handle a bit of extra weight. The ideal gasser would probably be more like a Zenoah 23 or 26 or comparible size in another purpose built brand.

I built one back in 1990 and it is still flying today. I originally bult it with an ASP .91 and it is now flying with a 1.20 stroker. If I were to build one again I would use the new OS 1.20AX. Here is a picture of it after about 18 years takin this summer and it still has the original Monokote on it.

Thanks for the help. I guess I will pay the $19.50 to RCM for the full size plans.
I have contacted GP by E-mail and phone but got no reply or call back.

New set of planes for $20 sounds like a bargain to me. Someone mentioned the tail. I think I would sheet the tail, at least the stab, if I were to build another one.

Unless it changed over the years it had fully sheeted tail surfaces. If I still had my plans I would pass them on, but I threw them out 2 years ago with a bunch of others.

ramcharger,

Make sure your instruction booklet has the addendum for beefing up the tail area. If you don't have it or you cannot get it, let me know and I'll dig up my instruction book and get it for you.

[:@]My instruction book doesn't mention an addendum. Page 6 describes
the technique for building the "tail feathers" and page 31 mentions "locking the
the tail feathers to the fuselage" but no addendum is mentioned. Also on page
3 under precautions when building there is no mention od and addendum.

daveopam

My Feedback: (9)

If memory serves me right. The addendum had to do with running screws into the stab from the bottom of the fuse to lock it in place. I can dig out the book if no one else has the right answer.
