The design goal of the Slingshot is to provide the speed of entry level general aviation aircraft, with all the fun, short field performance, and portability of ultralight aircraft. No mistaking what the Slingshot is all about. It is a fun flying, kick up your heels type aircraft. The aggressive stance of the Slingshot hints at what this aircraft is capable of doing. It jumps off the ground, zips through the air, sips fuel, and lands in shorter distances than any other aircraft in its speed range. All these features and performance are available at ultralight prices. Available in a wide variety of states of completion, from a basic do-it-yourself kit, all the way to our very comprehensive Quick Build kit.

HIGH PERFORMAN
cE
Many ultralight pilots, having gained experience and confidence in their aircraft, are looking for a faster aircraft to extend their cruise horizons. However they don't wish to make the huge jump into general aviation aircraft with the much higher operating costs, expensive annual inspection fees, poorer visibility and need for hanger rental.

 

The Slingshot is the next logical step. It provides the additional speed while retaining the short take-off and landing distance, impressive climb, light weight structure, superior visibility, and quick folding wings of ultralight aircraft. The Slingshot delivers the cruise speeds of GA aircraft and retains all the fun and economy of ultalight aircraft. Plus, the slingshot is capable of operating from the shorter ultralight landing strips. The Slingshot can be built with empty weight of under 400 pounds. With a Rotax 582 and typical options, the weight will be in the 450 pound range. This is a very high horsepower to weight ratio and is the secret for the tremendous performance potential of the Slingshot. We haven't forgotten the licensed pilots either. Many pilots are making the transition from GA aircraft to ultralight type aircraft. The Slingshot makes the transition easier as it provides more speed than typical ultralight type aircraft and it feels and handles more like a GA plane.

STURDY CONSTRUCTION
The Slingshot fuselage is built from strong, light weight 4130 chrome-moly steel -- like most high performance aerobatic aircraft. 4130 steel gives more strength with less weight than any other type material, and yet has excellent crash worthy characteristics. Wings and tails are made of aluminum with steel reinforcements at high stress areas.

COZY SEATING
The Slingshot has tandem seating. The rear passenger seat is designed for average size people, up to 175 pounds. The seating arrangement has the passenger's legs overlapping the pilot's seat. This allows the fuselage to be shorter and more compact. It also saves a lot of weight.


Although Kolb aircraft are easy to fly and have gentle flight characteristics, they are also high performance aircraft. We recommend training or some transition training before attempting flight in our aircraft.

GREAT VISIBILITY
Many may not consciously be aware of the fact, but it is true: the better the visibility, the more enjoyable and fun the flying -- the more visibility the better. We retained the pusher configuration to maintain the vastly superior visibility for which Kolb Aircraft has become known. With the Slingshot, you have more visibility than any other design. Keeping the engine in back also eliminates exhaust fumes and reduces noise levels.


FOLDING WINGS & TAIL
The cost of hangering airplanes today is one of the more burdensome aspects of aircraft ownership.  (A tie down may cost less in the short run, but is expensive eventually due to more rapid aircraft deterioration.) Those who otherwise feel they can afford to purchase an airplane, may not feel comfortable with the ongoing expensive monthly payments needed to store the airplane at an airport.

The Slingshot's very quick folding wings provide many alternatives to expensive hangar storage. The least expensive storage is keeping the Slingshot at home and trailering it to the flying site. Many Kolb owners find this a practical arrangement; also our owners can share hangars, and some store their trailer at the airport (for typically minimal fees). The compact size and light weight of the Slingshot provides an extremely easy to move around aircraft. Push it out of the trailer, pop out the wings, and go fly in about 15 minutes -- real time! At only 400 pounds, it is easy to move the Slingshot into and out of your garage, hangar, or trailer. The shorter span wings makes folding a breeze.
