Excepts from the Review

I have high expectations for a product from Sig Manufacturing Company because of its long history of quality products. It was no different this time when my giant Sig box arrived with the new Kadet Senior Sport ARF. I shook the contents out of the coffin-size box and immediately began inspecting everything. The quality of the covering was excellent and the construction looked impeccable. The Kadet Senior is one of those airplanes that everyone seems to recognize. It is a quintessential trainer with history going back more than 30 years and more than that with the smaller versions. I last built a Senior more than 20 years ago and it was popular for kitbashing among my club members. I flattened the wings to 2 inches dihedral, added ailerons, adapted it for a bolt-on wing, braced the tail, made it a tail-dragger, and powered it with a Saito 80 and later an Astro 40G on 21 Ni-Cd cells. When I saw that the company had come out with a version incorporating all of the things I had done to that one, I had to have it! As an instructor pilot, I always believe that everyone should have a trainer. It’s good for practice and for regaining confidence after a crash. I fly electric power almost exclusively now, and chose to power the Kadet Senior Sport with the recommended power system from Sig. The company offers several options—complete with manufacturer recommendations—and states its favorite of the bunch. How could I go wrong with that? Loops, rolls, inverted flight, stall turns, and Split S maneuvers, are all within the normal flight capabilities with the given power setup and settings. It performs inverted flight well. Just for fun, I set up flaperons and they slow the airplane to a crawl. They aren’t necessary, but this airplane is so much fun to fly and experiment with that I couldn’t resist.

Kit contents as they shake out of the box. The quality of the covering was excellent and the construction looked to be impeccable.


Servos set in wing and attached to control horn. Control rods are threaded with quality metal clevises.


The vertical fin is glued after horizontal stab is dry. Tape holds it perfectly aligned while the epoxy dries.


The Himax motor bolted in place and mount bolted to firewall with pre-installed blind nuts. THe recommended motor is a perfect match for the airplane.


A cavernous fuselage allows plenty of room for installation of a receiver and servos. A Castle arm Lock socket and key is installed for added safety.



Conclusion “Throw all my other airplanes away. This is the only thing I need,” is the answer I gave my wife when she called to see how the test flight went. This reminded me so much of my old kitbashed Kadet Senior from years ago that I immediately felt at home. As soon as he finished flying mine, my flying buddy ordered one for himself. How else can I say that this is a real winner? The traditional Kadet Senior is a great-flying airplane and this one is even better. If you’re an experienced pilot, it will provide tons of relaxation or excitement, depending on your setup. If you’re a beginner, it will carry you from learning through aerobatics. Congratulations Sig! I’m retiring my 16-year-old LT-25 as my primary trainer and crowning a new winner.

Can't say one thing bad about this aircraft I have an OS 60 in mind love. It getting ready to put a set of 40in floats on her this is a perfect float plain sig really did there home work when they came out with the sport model I think a child could have put it together

The Kadet Senior Sport was my first Kadet. It won't be my last ! Mine is powered by a Magnum .91 4 stroke, and is a blast to fly. The model retains stability at slow speeds and handles normal sport aerobatics well.

I just finished my Kadet Senior Sport and was also concerned about not being able to source the 6.5mm wing bolts mentioned in the "Minuses" section at the top of the review - just because I'm really obsessive about having spares in my field box, not because I broke them already! I emailed SIG directly and they replied that part number SIGRPNWB296 is a package of two replacement bolts, price is $2.80. That part number isn't on their website, but you can order them directly over the phone.

Plane is great. But I recommend stronger control rods. The rudder and airlarone rod stripped out. I was just lucky and got the plane down OK.
