i have till may to get this plane prepared. the flying, outside, till then here in NW ohio is iffy as best. i prefer ARF's. that's just me. built lots of kit plane along time ago. i love the flying part of this sport the most. ARF's give me this.
this Sig plane is an american classic.

The plane that I learned to fly RC on was the SIG Kadet Senior that I built over 20 years ago. Equipped as a 3 channel (engine, elevator, rudder). Powered with a Thunder Tiger GP42. I still have it, and I flew it a year ago after I gave it some upgrades. New battery, tank, receiver. Flies like you'd expect. Slow circuits, it will loop, fly inverted. It flies best in light winds. I've had a guy at the field suggest I add ailerons, bigger engine, less dihedral, but I would never do that. It's perfectly fine as a slow flying 3 channel. It might be boring for most to watch, but I love the slow circuits I do. Here's a current photo.

Tom, that is a sharp looking model. thanks for sharing. i too would not change that model from three channel.

i went with 18" extensions instead of the 12" in the directions. won't be using the "Y" hookup but will be using two channels so i can set up flapperons. it will be easier to plug in the wing at the field this way

Good to hear you are enjoying this build. Sig seems to make a really good ARF.

yes. the build is going well. epoxied the tail feathers on. everything was very true so it was easy to get things straight.

all the factory gluing seems very well done.

i would share pictures of my build, however i'm having issues with my computer. need my son to aid me with such.

the four planes that are closest are mine. prolly 14 years ago. that's a sig cap i had then. saito 150 in it. it was squirrely. i like sig products.

that's a friend in the pic.

Well capt1597, that's pretty impressive. What I find interesting is that you want a slow cruiser like the Kadet. I will tell you, I think you'll like having one. Low and slow easy circuits over field are a blast to me. Highly aerobatic? Nope. But you'll have plenty of fun with it. Press on.

i painted the aft side of the firewall, the inside of the landing gear area, and the wing mounting structual area with west system epoxy. i like to think that this will firm up these high stress areas for a long life for the model.
it's got a 24 hr cure time. very strong stuff.

i'm still pondering how i will mount the engine i have. OS72. straight up, to have the weight up near the wings to reduce the pemdulum effect for better stunting. prolly more exhaust goo. engine inverted for more pendulum effect and a more trainer fight characteristics, less exhaust goo. or sideways, but more side to side balance weight.

i always liked the look of the kadet with the engine straight up.
i least like inverted engines when starting.

i'm not a beginner. been flying model airplanes for 60 years. just adding a super slow flier to my hanger.

I love West Systems Epoxy, the wood will fail before the epoxy will. Should be ok as long as the plywood doesn't stress and de-laminate. I'd be wary of the landing gear plate. Happened to me once on a very very bad landing (crash) that tore out the landing gear mounting plate on my Great Planes Escapade. They had some pretty cheap plywood there. And I coated it like you suggested above. I restored the Escapade with some decent plywood and some blocks to lock it into the fuse. But that's your call.

I like my engine upright for ease of starting. But with my Thunder Tiger GP42 and the way the tank mounts, fuel tends to slowly drain into the engine before starting and flood. I've gotten into the habit of putting a clothespin on the fuel line to the engine. Once started, I pull off the clothes pin and it runs fine. Again do it the way you like. Your call.

so, it is a ways till flying season here. so i cut back the covering around the landing gear area and laid down some fiberglass and epoxy. super thin modeling glass. 4 layers. will recover, no problem. now a very strong landing gear area. will withstand all normal landings i'm sure. covered it with wax paper and smoothed it all out. hoping for very little sanding. we will see tomorrow

covering the fiberglass area with wax paper and smoothing it out worked well. no sanding was required. recovered the area, done.

You are like me. I like buying new blades, new bits and more sandpaper. I'll even buy it at the dollar store. Is it great? No. But I buy it everywhere. Blades and bits, I'm always interested in new. Harbor Freight, ebay, new blades and bits are always a good thing.
