About this Plan

Saker. Radio contol sport pattern model, for 40 power.

Quote: "Building and Flying Instructions for the Solution Aeromodel Company 'Saker'.

The Saker was designed to be the model pilot's first low-wing airplane, sort of a stepping stone from high-wing trainers to high-performance pattern and scale models. It's also an excellent advanced aerobatic trainer and sport flyer.

The light wing loading of the model allows it to be flown slowly without falling out of the sky. Stalls are gentle and the model has no vicious traits, like snap rolling when stalled, etc.

The Saker is a good and honest airplane, but like any model, it is only as good as it is built. So take your time and do it right.

Read through the instructions and study the plans and photographs before you begin. You will need basic modeling tools: hand drill, Xacto knife, pins, sandpaper, small clamps (clothes pins work well), a small square or draftsman's triangle,etc. A 24 x 48 inch piece of white building board (Celotex) or an acoustic ceiling tile placed on a flat, smooth surface makes a good building board that is easy to push straight pins into.

The materials and hardware items not included in the kit are indicated on the plans by an asterisk (*) after their names. White glue and epoxy are recommended for all glue joints. The new cyanoacrylate glues work well also, but we do not recommend them for gluing any high stress joints (firewall, landing gear mounts, dihedral brace, etc) Remember: He who builds an airplane on a crooked building board will have a crooked airplane.

Construction. 1. Cut center out of the fuselage formers using the templates on the plans as a guide. Glue 1/4 in sq balsa stiffeners to the formers. Glue 1/8 in ply doubler to former..."

Quote: "Steve, Here is an obscure one for you. The Saker was .40 size sport pattern ship that was sold by Solution Aeromodel of New Mexico USA back in the early 80s for a very short time. I believe this was their only kit. I bought a framed up kit from e-bay and decided more of the modeling world should have an opportunity to build one. Span is 51in. Length is 43in. Weight 4-5 lbs. Area 523 sq in, for .40 Power, 4-5 channel. By Stan Johnson. The Jan. 1983 Flying Models (RIP) review mentions the owner of the company was Ron Booth. This plane was also favorably reviewed by RCM (or MAN?)"

Update 10/12/2020: Added kit review from RCM, June 1978, thanks to RFJ.

Hi Steve, You know what: I really do like your site, especially because of plans/planes like this one. And I could write such an email at least once a week. Thanks a lot :)

A photo of my kit built Saker way back in 1980 [main pic, 006]. Finished with silk and Sig dopes. Great flying model to learn aerobatics on, which will slow down nicely on landing. Care must be taken to keep rear of the wing light to avoid lead in the nose. From Ontario, Canada,

Hello, A friend of mine who just refurbished his 40 year old Saker told me about your site. I am the original owner of Solution Aeromodel. The Saker was first sold in the mid 70's. I sold the company and the rights to it and my other design, a sport trainer named Solo MK II , to Ron Booth in 1979. The Solo and Saker used the same wing. The Saker kit was reviewed in Flying Models magazine by Bob Hunt. It was his second RC model after learning to fly. He liked it so much he did the review and put it on the cover of the magazine.
Ron stopped production in the early 80's. I still fly a Saker with a piped rear exhaust OS 46. The engine turns a 9 x 8 prop at 17,000 RPM. The model really scoots with that power.
I also designed what was a .60 size Saker that was never kitted. You could change the shape of the tail, wing tips, canopy, etc to look like different WWII era fighters. I called it a Fun Fighter. I still have the first one I built. It has the same great flying qualities of the Saker. Local modelers scratch built over 6 of them from my plans in the mid 80's. One of them actually built the fuse to look like a big Saker.
I used the airfoil from George Aldrich's Flight Streak control line models on all 3 designs. It's a great airfoil with a benign stall and a very wide speed range.
Model Builder magazine published a construction article on the Solo kit. The original Solo had a rolled cardboard tube for a main spar which acted as a jig to build the wing. It worked great in the very dry Southwest. When the kits hit the market in humid areas of the country the wing would twist around as the humidity changed. I went to a more conventional spruce spar wing construction but was able to maintain the self jigging aspect. The builder glued all the spars together on a ply joiner to slip the ribs over. Regards,

Thanks Stan, have set the date for this one as 1975, now. If you could send us through a scan of the unpublished 60-size Saker, we'd love to have that one too up here on Outerzone.

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
