Our roots go beyond the Aerolite. We have represented Challenger and Quicksilver aircraft, assembled customer airplanes, traded aircraft and supported owners across the ultralight and experimental market.
Challenger owners have access to kit-by-section purchasing, builder assistance and a broad catalog of field-tested upgrades and replacement parts.
We offer several Challenger payment approaches, including outside financing, pay-as-you-go purchases, paying for components as assembly progresses, and pay-in-full arrangements. Terms and third-party financing can change, so confirm current details with us before ordering.
We divide Challenger kits into four sections: tail, wings and ailerons, fuselage, and powerplant. The airframe cost is the same as buying the kit at once, although separate shipments add shipping cost.
