For Parts

The easy to build FireStar II SS is a side by side version of the FireStar II. It gives great climb performance  with the Hirth 3202 engine but can be fitted with  the Rotax 582 engine. This aircraft uses the stock FireStar wing and tail feathers, so if you own a FireStar II tandem seat, you can purchase a new cage and a boom tube from Kolb Aircraft and fit your wings, tail feathers, engine, and instruments to it and convert to side by side. (Call for details). With the gross weight of 850 lbs. and slow stall speed, it qualifies as an experimental kit build light sport aircraft... Perfect for Sport Pilot. The standard engine for the FireStar II SS is the Hirth 3202 equipped with a 2.58:1 gear reduction drive turning a 66 inch diameter fixed pitch propeller. This combination gives outrageous climb performance and a top speed of 80 mph.

Pictured above is the Kolb FireStar II SS.

The FireStar II SS is an extremely versatile aircraft. Its performance is truly amazing due to its light weight, generous wing area and large diameter propeller. The numbers do not adequately convey the performance profile. It must be seen to be believed. 

The take-off and climb rate of the Kolb FireStar II SS is truly astounding. No other light plane kit even comes close. This performance, combined with the good propeller ground clearance, allows for operation from many types of improved fields.

For strength and durability in airframe structures, aluminum and steel are superior.  The heart of the FireStar II SS, the fuselage cage, is made from strong factory welded 4130 chrome-moly steel. We also use 4130 steel in all high stress areas.   FireStar II SS wings have rigid truss ribs and a massive 5" aircraft aluminum wing spar, all  covered with Stits aircraft covering. Permanent UV protection eliminates fabric degradation.

The FireStar II SS, like all Kolb aircraft, utilizes traditional cable and push-pull tube controls which give a solid feel. The half span ailerons have good roll authority at higher speeds while still being powerful enough at lower speeds to retain roll control even through a stall. It takes very little power to maintain minimum flying speed and such flying is more enjoyable in a Firestar II SS because of engine noise and fuel consumption are at a minimum. Optional  hydraulic brakes provide for sure stops so the FireStar II SS can be landed and stopped in very tight areas. The optional individual heel pedals allow for a tighter  turning radius which improves the already excellent ground handling.

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.

The FireStar II SS is a great sight seeing aircraft and the fact is, better visibility makes more enjoyable flying. The pusher configuration of the FireStar II SS provides the vastly superior visibility that Kolb aircraft have become known for.

is the Kolb FireStar II SS.

There is 360 degree visibility from the cabin and the  clear lexan gap seal between the wings over the cockpit lets you see straight up. The optional doors allows for comfortable flying in cooler weather and can be removed easily for real open flying. The rear engine eliminates exhaust fumes and reduces noise levels.

Like all Kolb aircraft, the FireStar II SS has folding wings and tail which allow for easy storage or trailering.  The tail folds up and the wings fold back along the fuselage in about 15 minutes by one person.  Everything stores right on the airframe


The FireStar II SS has a spacious 42 inch wide cabin (36 inches at the hips) and with adjustable rudder pedals, even taller people can be
comfortable. The optional full enclosure doors are bulged out to allow for more shoulder room (41) inches wide for the occupants and can be removed easily for real open air flying.
