Mini-Max buying guide

Building a Mini-Max in a garage: space, tools and builder experience

Mini-Max aircraft have been built in one-car garages, basements, barns and hangars for forty years. This guide uses the real dimensions of each model to show how much room the build actually needs at each stage, lists the tools most builders use, and is honest about the experience that helps.

Dimensions and build-time ranges are Mini-Max USA's owner-audited figures. Space guidance derived from them is labelled as guidance, not a rule.

1. How big is a Mini-Max?

Every current model is a single-seat, wood-and-fabric aircraft with a 25 to 28½ foot wingspan and a fuselage 16 to 18 feet long. The table lists the owner-audited reference figures used on the model pages.

1950S AeroMax	High-wing	28 ft 5 in	17 ft 10 in	71 in	14 in (open-air step-through)	429 lb	738 lb

Empty weight is configuration-sensitive: engine, starter and electrical system, brakes, cowling, tanks, paint, instruments and workmanship all change it. Use the model page and the Compare tool for the full specification and its confidence notes.

2. Space by build phase Guidance

A Mini-Max is not built as one 25-foot object. It is built as a series of sub-assemblies, which is why so many have come out of small shops. Working from the dimensions above:

Bench phase: ribs and tail

Wing ribs are built one at a time in a jig on a flat bench, and the tail surfaces (fin, rudder, stabiliser, elevator) are each a few feet across. A sturdy, flat workbench, dry storage for the wood and good lighting are the real requirements. This phase fits in a corner of a one-car garage or a basement, which is why Mini-Max USA's FAQ says many builders start in small spaces.

Sub-assembly phase: fuselage and wing panels

The fuselage is about 16 feet long (17 ft 10 in for the AeroMax) and under 2½ feet wide, so it fits lengthwise in a standard one-car garage with room to walk round it. Each wing panel is roughly half the span, in the 12 to 14 foot range, and is built flat on a long bench or sawhorses. Most garages can hold the fuselage and one wing panel at a time; two panels and the fuselage together need a two-car bay or a long wall.

Final assembly and rigging

With both wings on, the aircraft spans 25 to 28½ feet, wider than the interior of most two-car garages. Builders typically do final assembly, rigging and engine runs at the airport or in a hangar, moving the fuselage and wing panels there on a trailer. Plan that move from the start.

Rule of thumb from the dimensions. A one-car garage gets you through ribs, tail, fuselage and wings built one panel at a time. A two-car garage lets you keep both wing panels and the fuselage under one roof. Only final assembly needs the span, and that can happen somewhere else. Keep a clear path to the door wide enough for the fuselage and a wing panel.

3. Shop conditions that matter

Temperature and humidity. Very important. Glue, varnish, wood storage and covering work all depend on proper conditions. Follow the adhesive and covering-system instructions, keep materials dry, and do not build in conditions that compromise cure quality or wood stability. In practice that means heating or waiting out cold snaps for epoxy work, and keeping wood off concrete floors.
A flat reference surface. Ribs, tail surfaces and fuselage sides are built on a flat bench or table. Flatness matters more than size.
Dry, organised storage. The kit arrives as a lot of long, light pieces. Racks along a wall keep aircraft-grade wood straight and dry and keep parts findable.
Light and dust control. Good light for inspecting glue joints; a plan for sanding dust before covering and finishing.
Materials. Use the materials specified in the plans or supplied by Mini-Max USA. Hardware-store plywood and lumberyard stock are not substitutes for structural aircraft parts.

4. Tools

This is not aerospace manufacturing; it is careful craftsmanship, and most of the work is done with common hand tools and basic shop equipment. You probably own many of them already.

Very helpful

Flat workbench
Drill press and a good hand drill
Band saw
Sander (plus plenty of sanding blocks)
Clamps, as many as you can gather
Straightedges, squares and measuring tools

Also used

Hand tools for fitting and assembling metal parts, and riveting tools
Mixing cups, spreaders and brushes for T-88 epoxy
The covering tools and consumables your covering system calls for
A varnish brush or spray setup for sealing wood before covering

Not required for a standard build

Welding equipment
Advanced machining
A professional machine shop

Choosing the Kit with Prefab Wing Ribs and Prefab Metal Parts reduces the metal layout and cutting you do, which also reduces the tools you need for it.

5. Skills and experience

Woodworking experience helps, but it is not required if you are patient, careful and willing to learn. The build is a series of small tasks: measuring, cutting, sanding, fitting, gluing, clamping, drilling and checking your work. The skills Mini-Max USA lists for its full kits are:

basic woodworking, measuring and drilling;
riveting and assembly of metal parts;
epoxy work and fabric covering.

Two habits matter more than prior experience. First, a builder log with photos, receipts, notes and dates, which documents that you built the major portion of an Experimental Amateur-Built aircraft for education and recreation. Second, asking early: send Mini-Max USA photos, the step you are on, your model and plans reference, and you will get a clear answer. Builders also lean on EAA chapters, online groups and mentors; you are not building alone.

Each full-kit product page has a Build Time & Skill Level section with the skills for that model. Start with plans ($299.99 for most models) if you want to study the drawings and the build sequence before committing to a kit.

6. Time Estimates

Mini-Max USA's owner-audited estimates run from 250 to 400 hours for a Base Kit and 175 to 300 hours for the prefab level, depending on the model. The guide Base vs. Prefab vs. QuickBuild lists them model by model.

Turning hours into a calendar is simple arithmetic, and the honest answer is that everyone builds differently. Example At 8 hours a week, a 250 to 300 hour Base Kit is about 31 to 38 weeks of steady work, roughly 7 to 9 months; a 350 to 400 hour model at the same pace is 44 to 50 weeks. Some people finish quickly, others enjoy the journey over several years. There is no wrong timeline; the goal is finishing safely.

7. Getting it to the airport

Some builders trailer or transport their aircraft with the wings removed. Plan carefully to protect the airframe, covering, controls and tail surfaces, and think about the trailer before you need it: the fuselage is 16 to 18 feet long and each wing panel is in the 12 to 14 foot range. Once flying, indoor storage is strongly preferred; wood-and-fabric aircraft last much longer when protected from moisture, UV, wind, pests and temperature extremes.

8. When the garage runs out

Projects stall when life gets busy, the workspace gets crowded or a step feels unclear. Builder Assist lets you bring your Mini-Max project to Mini-Max USA in Niles, Michigan and work on it alongside factory-trained builders, with your project overseen by an Airframe & Powerplant mechanic. It is hands-on: you work on your own aircraft and remain the builder. It is also an option for a stalled project or for the final-assembly phase when you have no hangar yet. About Builder Assist.

9. Questions builders ask

Can I really build a Mini-Max in a one-car garage?

You can build most of it there. Ribs, tail surfaces, the fuselage and the wing panels are each built as separate assemblies on a flat bench or sawhorses, and larger components can be built separately and moved later. Final assembly with both wings on needs a span of about 25 feet or more, which is wider than most garages, so builders usually do that at the airport or in a hangar.

What tools do I need?

Most of the work is done with common hand tools and basic shop equipment. A drill press, a sander, a band saw, plenty of clamps, straightedges, measuring tools and a flat workbench are very helpful. No welding or advanced machining is required for a standard build.

Do I need woodworking experience?

It helps, but it is not required if you are patient, careful and willing to learn. The build is a series of small tasks: measuring, cutting, sanding, fitting, gluing, clamping, drilling and checking your work. The skills are basic woodworking, riveting and assembly of metal parts, and epoxy and fabric-covering work.

How long will it take?

Mini-Max USA estimates 250 to 400 hours for a Base Kit and 175 to 300 hours for the prefab level, depending on the model. Build time also depends on your experience, your workspace and how regularly you get shop time; a careful builder working steadily makes much faster progress than someone with short, irregular sessions.
