Sig T-Clips EP

"T-CLIPS" is no ordinary clipped wing Taylorcraft. Originally a stock 1939 Taylorcraft, this is the only clipped wing T'craft in the world currently flying airshows with an original size engine. Airshow pilot Erik Edgren refers to this as "Twistin It Old School". SIG is proud to team up with Erik and offer a new R/C model of his one-of-a-kind airplane.

Designed for electric power, the new SIG T-CLIPS EP is a pure aerobatic delight. It's not meant to be an exact scale model, but more of an everyday no-frills flying field favorite.

Voted by pilots as the "Best New R/C Airplane At SEFF 2013".

Wing Loading 16.5 - 18.3 oz/sq.ft. 50 - 56 g/sq. dm
Radio Required 4-Channel
Recommended Power: 500-800 watts

Special notes about electric from Dave: I've been very excited about this fine model hitting the streets. It's an excellent high wing aerobatic model. Scale looks with a wide speed envelope. I have done an extensive work up of power systems I could recommend below. You don't get this kind of analysis from anybody else, even SIG. Think of lower capacities as the cell count increases, for 6S, I'm thinking about high quality 2200's, think about larger packs up to 4200 for 3S, maybe a 3300-3700 for 4S, a 2200-3300 for 5S. Some alteration of battery tray may be required and is not investigated as of this moment.

Sig Kadet Seniorita

This compact version of the KADET SENIORITA is designed for modelers who have a small car or apartment-size workshop. The SENIORITA features the same forgiving flight characteristics of the larger SENIOR, but in a smaller package.

Both the KADET SENIOR and KADET SENIORITA are also popular with experienced fliers who are tired of the nerve racking panic that can accompany a faster model. The KADET SENIORITA flies so slowly and gently that just about anyone can handle it on their very first try! If the student pilot gets confused, merely let go of the control sticks and the KADET SENIORITA will recover itself and return back to level flight.

Specifications:
Wingspan: 63 in 1600 mm
Wing Area: 746 sq in / 48 sq dm
Weight: 3.75 lbs / 1700 g

Sig Kadet LT-25 - Product Image
Click for larger image

Sig Kadet LT-25

The Sig Kadet LT-40 has become the R/C trainer of choice at many club fields. Not long after it's introduction, we started getting requests for a smaller version of the same airplane. So here it is - a compact version of the LT-40 - the new Sig Kadet LT-25. When price shopping this kit, be sure you understand our super low flat rate shipping means total cost to your door is probably the lowest on the planet.

"The R/C Trainer That's All Laser Cut", As you would expect, the new LT-25 inherits all the same gentle flying characteristics of the other legendary Sig Kadets. It has the same light wing loading, which allows it to fly slow enough to give the student pilot time to think and react. It has the same "hands off" stability on all axis. If the student pilot gets disorientated, simply let go of the sticks and the LT-25 will recover and return to level flight within seconds.

Specifications:

Wingspan 63 in 1600 mm
Wing Area 724 sq in / 46.71 sq dm
Weight 4 - 4 1/4 lb 1814 - 1928g
Wing Loading 12 - 13 oz/sq.ft. 3662 - 3967 g/sq-m
Radio Required 4-Channel
Recommended Engines .25 - .32 cubic in (4.1 - 5.2 cubic cm) 2-Stroke
.20 - .26 cubic in (3.3 - 4.3 cubic cm) 4-stroke

Special notes about electric from Dave: This model makes an excellent electric conversion and is perhaps the most popular one of all time. Super light weight, large as or even larger than most 40 size trainers. The only lighter weight 40 size trainer on the market is the Radical RC Intern 66.

Sig Kadet LT-40 - Product Image
Click for larger image

Sig Kadet LT-40

Like all Sig Kadets, the LT-40 behaves perfectly in flight, with true "hands off" stability on all axis. If the student pilot gets disoriented, simply let go of the control sticks and the LT-40 will recover itself and return to level flight within seconds.

Because the Kadet LT-40 is bigger than the average .40 size trainer, it has a much lighter wing loading, which lets it fly slower! Slower speed gives the student pilot more time to think and react to what the model is doing, thus making it easier to learn to fly R/C. Every major part of this kit has been pre-shaped, sawn, die-cut, laser-cut, routed, or whatever it takes to make it ready-to-install right out of the box.

Setups below would be my first picks depending on your purpose for the model. If your trying to learn or train a beginner, or just want a mild model with enough power to get out of trouble, pick setup around 1000 to 1400 foot per minute climb rate (fpm). An expert can do quite nice aerobatics on 1000 fpm, 1400 fpm and above is enough for first season pilots. Setups 2000 fpm and higher is agressive power.

Specifications:

Wingspan 770 in 1778 mm
Wing Area 900 sq in / 58 sq dm
Weight 5.5 - 6 lb 2494 - 2721g
Wing Loading 14 - 15.5 oz/sq.ft. 4272 - 4730 g/sq-m
Radio Required 4-Channel
Recommended Engines .30 - .40 cubic in (4.9 - 6.6 cubic cm) 2-Stroke
.40 - .50 cubic in (6.6 - 8.2 cubic cm) 4-stroke

Special notes about electric from Dave: This model makes an excellent electric conversion and is perhaps the most popular one of all time. Super light weight, large as or even larger than many 60 size trainers. For UAS purposes, the under wing compartment is 3" wide, 5 5/8" deep and 12 3/4" long.

Sig Kadet Senior - Product Image

Sig Kadet Senior

First attempts at R/C flying should be with an inherently stable model that flies slow enough to give the student pilot time to think and react. The Kadet Senior is the result of designer Claude McCullough's 50+years in the model airplane hobby. Everything about the Kadet Senior has been designed to make it the easiest to fly trainer in the world.

The"Hands Off" Trainer; High-wing configuration, large tail surfaces, and generous dihedral for true "hands off" stability. The Kadet Senior flies so slow and gentle that just about anyone can handle it on their very first try! If the student pilot gets confused, simply let go of the control sticks and the Kadet Senior will recover itself and return back to level flight. Flat-bottom airfoil, light weight construction, and a super light wing loading allow the Kadet Senior to cruise around at low speeds. All-balsa design with a strength-to-weight advantage that ARF trainers can't approach

Specifications:
Wingspan: 78 in 1981 mm

SIG Kougar Mark IIWaiting List Order

If you're looking for an R/C model that is easy to build and exciting to fly, the KOUGAR is for you! This sleek jet-style airplane has a fully symmetrical wing section for smooth pattern-like aerobatics. Ample wing area and a thick airfoil provide outstanding slow speed stability. Built-in wing "washout" eliminates tip stalling, enabling the Kougar Mark II to be slowed down to a walk for realistic nose-high landings. The Kougar Mark II is highly recommended as an introduction to low-wing flying and learning aerobatics. Fully Aerobatic Smooth Control Response Don't let the Kougar's racy lines worry you. Construction of this sport model is simple and straight forward. The load-carrying and equipment-carrying portion of the fuselage is basic balsa box structure. Once that is built, you add a molded plastic fuselage top, a molded clear plastic canopy, and a molded plastic cowling, to give the Kougar its modern jet-style shaped. Price includes Sig Mfg.'s $20.00 shipping surcharge.

Sig Somethin' Extra Kit

The new Sig Somethin' Extra has it all - good looks, incredible performance, Sig quality balsa and ply construction and every part in the kit is laser-cut!

This kit can literally be built as fast as the modeler can apply CA glue and accelerator. Fantastic flight performance using either 2-stroke or 4-stroke engines. The aerobatic capabilities of this model are virtually unlimited due to its thick airfoil section and very light wing loading. A perfect club contest airplane.

Special notes about electric from Dave: This model makes an excellent electric conversion. My first large electric was one of these on 20 1750FAUP Cells. Yikes, I'd love to do another one with modern packs! Here is how I'd do it. Yes, this is same chart as the 4 Star 40, similar weight and wing area. An under recognized yet excellent electric conversion model. Good weight to wng area. A little troublesome to get large NiMH packs into due to the wing tube. However with Lipo's it's super easy to fit the pack. Below are my suggestions for a range of practical power systems.

Sig Kavalier

The heart of this beautiful airplane is it's superior wing design! The light, strong, built-up balsa structure incorporates built-in wingtip washout for superior stability and control. Even expert pattern fliers are impressed with the Kavalier's smooth, responsive flying ability. Make perfectly coordinated, in-the-groove turns. Fly through any aerobatic maneuver with rock solid precision. Flare out for slow, main gear only landings with no tendency to stall or snap roll. Highly recommended as a student pilot's second model! Balsa fuse, tail and wing with built in washout. Build it bolt on or rubber band mount wing with semi-symmetrical airfoil. Steerable nose gear, pre-bent aluminum landing gear and rugged plastic cowling and canopy included as are glow engine mount, full size plans and photo illustrated instruction book. Specifications:

Recommended
Engines .29 - .40 cu. in. (4.8 - 6.6 ccm) 2-Stroke

Notes from Dave: This is absolutely my favorite glow sport ship of all time. It's a classic kit. There was just nothing more exciting on trainer night than to have a graduated student come up with one of these for his 2nd or 3rd aircraft and ask me to test fly it. I dare say, I'd put a whole tank through the model and say, yes, it's still my all time favorite! The model is very pattern like for it's size, super smooth and yet retains all the personality of weekend sport ship. Friendly yet aerobatic and even aggressive if you set the throws for more spirited performance. They land like a dream, are utterly trustworth in any situation. You'll love it as I do.

Sig Riser 100"

The Riser 100 is an excellent choice for the newcomer who wants to get started in soaring, or for the already experienced "glider guider" who wants a relaxing, easy-to-build "floater".

The Riser 100's modified Eppler 205 airfoil and 1000 sq. in. of wing area gives you the ability to fly in nearly any weather.

Sig Wonder

The Wonder is best described as a very fast, go-where-you-point-it, turn-it-quick-or-it'll-be-gone kind of plane designed for hot-thumbed R/C pilots. With an .09 or a .10 size engine, the Wonder is actually a very nimble, aerobatic, smooth flying sport plane, but with a snarling .15 or .19 up front it's a hand- launched hot rod! Landings are no sweat thanks to the thick symmetrical airfoil and the light wing loading.

Specifications:
Wingspan 37 1/2 sq.in. (952 mm)
Wing Area 338 sq.in. (25 sq dm)
Weight: 26 - 38 oz 737 - (1077 g)
Wing Loading: 11.1 - 16.2 oz/sq ft (423 - 4943 g/sq m)
Radio Required: 2-Channel (ail, ele) or 3-Channel (ail, ele, thr)
Recommended Glow Engines .09 - .19 cubic inch (.58 - 1.23 cc) 2-Stroke

Special notes about electric from Dave: This model makes an excellent electric "muscle" model. Often overlooked since SIG does not offer an e-version or any electric power system setup info. It's easily adapted. Below are my suggestions for a range of practical to extreeme power systems.

SIG King Kobra

If a fast roll rate, sizzling vertical climb, and dazzling good looks turn you on, take a close look at the King Kobra's the largest version of the Kougar, Kobra series.
The foam core wing and unique fuselage construction get you in the air fast with a model that looks as good as it flies! For general sport flying, the King Kobra flys great with a sport .60 R/C engine and the standard fixed landing gear. However, for those who want to soup this model up to the max, the building instructions include tips on tuned pipes and retracts. A fully symmetrical wing and airfoiled stabilizer make the King Kobra fly super smooth. It can make an average Sunday flier look like an expert!
