Let's See How These Pictures Are Received
Here are some more pictures of my SIG Air Force. The Kadet Senior was built with my sons, when they were about 7 and 8 years old, in 1992 or 1993. I re-named the Banshee to Countess, as it has popular modifications. The Primary Force is not the SIG ARF, but Mikey Pratt's short kit.
About 10 years ago, I cut the wing in half, and made joiners to preserve dihedral and strength.
Instrument panels and pilots.
This will explain the registration number of the aircraft- C-ENFI: Co-Ed Naked Flight Instruction. Well, it was funny, back in the day.

Did you remember the doublers in the tail that are not mentioned in the manual? Also eye ball the fuse, mine had a twist in it because the last former had to go in a certain way and was backwards in mine. I don't remember if I posted my mods for the struts, I didn't do the SIG struts, since I had already built struts before they acknowledged the issue.
I may sell mine after I repair it, wasn't too happy with how it flew compared to the other planes I fly. It flew nice, but was just too slow on the inputs and is one of those that has to be turned before you actually want to turn it. I have other uses for the DA100.

Thanks for the reply acdii,
I did get the rear doublers installed on the inside. The only gluing I've done to this point is the laminating and the landing gear mount. For now the fuselage is held together with the wedges and the tail is laminated and drilled for the horizontal stabilizer front dowel. I've fabricated and replaced a couple of the fuselage formers near the tail as well as the tail wheel mounting parts and a couple of the horizontal stabilizer mounting pieces. I've done test fitting of the rudder hinges including the removable one, tail wheel mount slot and tab, horizontal stabilizer mount slot and tab all of which I had to do some fabrication to replace the supplied pieces. I will double check the fuselage when I get it back on the bench, but I think it is straight.
Sorry to hear you are disappointed with the performance. I have had a 1/3 scale cub and I expect this to have some of the same characteristics. Like you I have other planes that handle much better than what I imagine this one will. I also fly turbines but this one is intended to cover the opposite end of the range when I'm ready for a slow day.
After I hacked the front wing mount and the center rib, I see what you were talking about with the sloppy fit of the ribs. I will definitely reinforce those joints.
Thank again,
Al

Sig King Kobra taildragger
GUS THE I.A. Nice King Kobra. Do you have any pics of the underside - something that shows the landing gear arrangement and tail wheel linkage?

Surprise! Here is the underside of the King Kobra.
I am tired of seeing checkerboards on the underside of peoples' airplanes, therefore I created a certain "slant" to the design. I love the results, and the other pilots like it, also.
The L.G. is mechanical, and the tailwheel was a real bear to make function for steering, although it does not retract. No accommodations are provided for these alterations in the kit, so I thought about it for a while before launching into it.
I'm really proud that all of the diamonds "line up" over the entire underside. If you look closely, you will see it, too.
Looks simple, but lots of tinkering went into making the tailwheel steer.

When I scratch built my Kadet LT-40 taildragger I ran into the problem of the rudder well in front of the elevator. A problem for taildraggers. This was my solution. Works good for me. It can all be removed for maintenance.

I added a second pushrod to the rudder servo with a shock eliminator, and ran the pushrod through a slot using a reverse Z bend. Hundreds of flights and still works perfectly.

Sign me up
I got 2 King Kobras (had 3 but one took a dirt nap) and a Kougar. Looking to get another Kougar and a Cub is also in the future. Building some basic kits to get my skill up first. Always had ARFs until this point.

Well here is number two. Did a different kind of covering on the fuse. It’s painted then covered with Doculam. Then the wing is covered with monocoat which I prefer. But its what the costume ordered lol.
#3523
My Feedback: (149)
Hey Capt, Was curious of the process you used and your opinion of the Doculam. I have some, yet unused, and have read some different techniques of applying. Seems some have lightly prepainted the underside, . . . some painted top side, but all seem to still need sealing to fuels.
Thanx

I found that the gas released by the glue gets trapped and causes the film to look cloudy. I don’t recommend that. He has reported that it’s pretty tuff. After a crash it was pretty much untuched.
My issus Is I can’t paint worth a darn so the prosses for me is not good. But it does work well if you can paint.

I'm finally able to share pictures of my SIG Air Force.
King Kobra, taildragger, retractable landing gear, inverted engine, neato wing and stabilizer tips, steerable tailwheel
Albert Einstein flies the King Kobra.
SIG Twister, albeit "Fancherized" is a great flying control line plane!
Twister that I built for a friend, with my own design logo.

Wondering about the unique, scarfed wing and stab tips on the KK; is this a mod used to avoid high speed flutter on aileron/elevator? Did you have to lower the tank to accommodate the inverted engine? Also wondering if the Sig Primary Force is a one-off kit - I know it was once offered as an ARF but was wondering if you could elaborate on the Mike Pratt short kit...
