Kolb Aircraft
USA Part 103 Buyer’s GuideKolb Aircraft
The wings fold. So does the tail. Kolb has been shaping ultralight kit design since the 1980s and the folding airframe is the reason: this is one of the most trailered designs in the country. The FireFly is the only Part 103 Kolb. Everything else in the catalogue is LSA or experimental.
1OF 7 IS PART 103
The FireFly. FireStar, FireStar II SS, Slingshot, Kolbra, Mark III Classic, and Mark III Xtra are not. One brand, one ultralight, six aircraft that need a licence. Order carefully.

The lineup
One Part 103 Kolb.
Factory Custom Air quick-build kit, the single completion tier on offer. Folding wings and tail, tricycle or taildragger, canopy or open cockpit. Kolb states the float option still meets Part 103.
254 lb is the published empty weight
That is the limit itself, not a margin under it. A canopy, floats, skis, and instruments all move that number, and Kolb sells all of them. Track your options with the factory and weigh the aircraft you end up with.
Six Kolbs that are not this one
FireStar, FireStar II SS, Slingshot, Kolbra, Mark III Classic, Mark III Xtra. All LSA or experimental. Same folding heritage, same shop, different rulebook.
Who it suits
- Pilots who need the wings to fold every single day, because it lives in a garage.
- Owners who plan to trailer the aircraft to where they want to fly it.
- Builders who want a factory-supported kit with real documentation behind it.
- First-time buyers who want a name the community already knows and stocks parts for.
What you give up
- Kit only. There is no factory ready-to-fly FireFly.
- The folding mechanism adds a step to every flight. That is the trade for the garage.
- No published pricing. Every conversation starts with a quote.
- Six of the seven Kolbs you will see on their site are not Part 103.

How to reach them directly.
Sales and customer support are separate inboxes. Say FireFly and say Part 103 in your first message.
Part 103 compliance is yours
An aircraft marketed as Part 103 capable can exceed the 254 lb powered empty-weight limit once engines, instruments, and options are added. The FireFly starts at the limit, so every option you add is a conversation with the factory. You weigh the finished vehicle and you confirm compliance with 14 CFR 103 before you fly it. See the Part 103 disclaimer.
