Quicksilver Aircraft
USA Part 103 Buyer’s GuideQuicksilver Aircraft
The longest continuous production history in ultralight aviation. Quicksilver is the name most people picture when they picture an ultralight, and it has the deepest dealer network in the sport. The MX-103 arrives fully assembled, which is rare in a category that mostly hands you a box.
250LB EMPTY, 24 MPH STALL
Four pounds of margin, and one of the lowest published stall speeds here. A 24 mph power-off stall is the number that keeps beginners alive. It is also the legal ceiling for Part 103, and the MX-103 sits right on it.
Published today: MX-103 from under $18,900, fully assembled.

The lineup
One Part 103 Quicksilver.
Fully assembled, the only tier offered. Open cockpit, nosewheel, tube and fabric. Floats and skis are factory options.
Four pounds of margin, and floats on the menu
250 lb published against a 254 lb limit. Floats, skis, and a chute all weigh something and Quicksilver sells all three. Have the dealer put the weight in writing for your exact configuration.
Most of the family is not Part 103
The two-seat MX Sport, Sport 2S, and GT 500 are LSA. Only specific single-seat configurations qualify. The brand is famous for aircraft that need a licence, so be precise about which one you are buying.
Who it suits
- Buyers who want a name their insurer, their field, and their neighbours already know.
- Anyone who does not want to build. Fully assembled is the only tier, and almost nobody else here offers that at this price.
- Owners of an existing Quicksilver who need authoritative parts and service.
- Pilots who want the classic open-cockpit ultralight and a national dealer behind it.
What you give up
- Sales and parts route through Air-Tech Inc., not Quicksilver directly. Your relationship is with the dealer.
- Pricing goes through a dealer rather than a public sheet.
- Open cockpit. Your climate decides how much that costs you.
- No folding wings, so storage is your problem.
Verified contact
How to reach them directly.
Say MX-103 and say Part 103. The brand sells more LSA than ultralights and the dealer will quote what you ask for.
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. With four pounds of published margin and floats on the option list, that is a live question here. You weigh the finished vehicle and you confirm compliance with 14 CFR 103 before you fly it. See the Part 103 disclaimer.
