About this Plan

Sig Kadet - Radio control trainer for .19 - .40 engines. This is the plan from the original 1972 Kadet design, which is now out of production and unavailable. The 3rd plan sheet shows ailerons modification.

Update 24/01/12: Ed mailed in to say: "The formers on the Kadet are complete. There was only the ply firewall, the main ply cabin former at the front of the wing, and two balsa formers for the rounded top section at the nose. everything else was built-up stick cross-members, from the trailing edge right back to the tail."

I had a hobby shop back in Michigan in the early 70s when the KADET was very popular. I sold a ton (I exaggerate) of KADETS and as the store trainer taught many beginning RCers. I found that I made it a much better flyer by lowering the trailing edge of the 'stab' 5/16" therefore making the wing and stab incidence the same. Also most were using .35s or .40s. Some added ailerons but the adverse yaw was extremely bad. I also built one as a tail 'dragger' and with the incidence modification it was a great flyer.

Hi Steve and Mary, thought you might like to see my recently completed project, a SIG Kadet Senior [more pics 003]. Just before Christmas, George Thompson, one of our club members, brought me a partially completed Sig Kadet Senior. After looking it over for a few days, I knew I couldn't make it light enough for the electric power I already had, so I gave it away. It was a little rough (maybe a lot rough) so Tom English inherited it because he doesn't care what it looks like. Before I disposed of the model, I measured the whole thing and re-drew the plans, leaving out half the wood and ALL the heavy stuff. Most Kadets weigh between 7 and 8 pounds. Mine weighs exactly 4 pounds, with battery. Covered with Doculam and painted with Rustoleum, an AXI 2820 motor with 3 cell 3200 lipo pulls it just fine, in fact it outperforms the heavy one I gave away, with Saito 56. The Kadet Senior is one of the all-time great model designs, probably never available as a plans download because SIG still produces the kit. They were really fine kits in the past but George's version was not so great. SIG has been in financial trouble since the company was sold, hopefully they will get their act together and this great design will be around for years.....

Thanks Doug, great comment and super photo. I'm assuming that's you with the plane?

Yes that's me, a little long in the tooth compared to the last pic I sent you from 1974 with the Nomad [OZ id 6264]. The Kadet was really easy to build from the simplified plans, ready to cover in one week. Notice the nose is left square instead of the rounded kit design. I lightened up the tail a lot in order to balance with the little motor, needed no ballast at all. I did have trouble with the paint though. I love Doculam, but since it's clear it needs to be painted or you can't see it in the air. Several models covered and painted with Rustoleum turned out fine, however I screwed up and tried a new version of Rustoleum called "2X". Supposedly it covers twice as much as other paints per can. Don't believe it, they just made the paint thicker and it doesn't spray as well. I had to remove the paint from half the wing and start over, a real pain in the butt. I only had problems with the yellow color, red worked fine. I've learned my lesson though, back to the old standard Rustoleum from now on. Krylon also sprays very well but doesn't stick as well to Doculam. Don't know if Doculam is available in the UK, might be worthwhile to Google it and give it a try. I've used it on everything from a Comet rubber model to the Kadet and it works fine on everything. Dirt cheap, mine was the 1.5 mil thickness, 25" x 500' roll cost $33, including shipping. 500 feet will last a looooogg time. It's so cheap I've used it for masking film, then just threw it away. My favorite paint scheme is just a little freehand color trim like on the Sparky, leave the rest clear. Apply it just like MonoKote, but use a little more heat.....See another pic of the Kadet [more pics 004], taken the same day, still Winter as the grass hasn't started to turn green yet. Picture was at our club field in Ashville Alabama.....

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.
