Affordaplane Aircraft
USA Part 103 Buyer’s GuideAffordaplane Aircraft
The cheapest way into the air, and the longest. Affordaplane sells drawings, not aircraft. Eighteen dollars buys you the plans. Everything after that, the material, the engine, the hardware, and a year or more of your evenings, is on you. We grade them unrated because no price here buys an airplane.
$18.95IS NOT AN AIRPLANE
It is a plan set. Budget the engine, the material, the hardware, and the hours. Anyone quoting you a flyable A-Plane for the price of the plans is counting wrong.
Published today: Digital plans $18.95. No kit is sold.
What it can and cannot do
The capability table.
Yes published as standard · Optional variant-dependent · No not available
The lineup
One design.
Sold as digital plans or printed plans. Five engine options are documented in the drawings; you buy the engine yourself. Widely referenced in the DIY builder community as the lowest-cost path into a homebuilt ultralight.
254 lb is the published empty weight
That number is the limit itself, not a number under it. A plans-built aircraft weighs whatever you build it to weigh. Every choice you make in your shop moves it. Weigh yours.
Who it suits
- First-time builders on the tightest budget there is.
- Anyone who wants the cheapest possible path into homebuilt aviation and has the time it actually costs.
- Hands-on builders who want to source every part themselves and enjoy that.
What you give up
- This is a plans supplier, not a manufacturer. There is no kit and no factory support.
- Every part is builder-sourced. That is the job, not a footnote.
- Documentation and support are lighter than the name-brand builders.
- Contact is a personal Gmail address rather than a domain mailbox.

Confirm everything with them before you buy or build.
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. On a plans-built aircraft that risk is entirely in your hands. You weigh the finished vehicle and you confirm compliance with 14 CFR 103 before you fly it. See the Part 103 disclaimer.
