Same company. Same laser cutter. Same Colorado address. But two very different building philosophies — and knowing which one fits your workbench is the first good decision you’ll make before the glue bottle comes out.

Stevens Aeromodel produces two distinct lines of laser-cut balsa kits. They share a name, a building philosophy rooted in precision engineering, and a commitment to quality materials. What separates them is something more fundamental: the role of the plans — and what the laser cutter is actually for in each line.

The Stevens Aeromodel Way

In a Stevens Aeromodel kit, the laser cutter is the pattern-maker. Every part ships pre-cut to final shape — there’s no template tracing, no cutting parts from sheet stock, no building board required. The parts interlock with tab-and-notch precision, self-jigging the assembly square and true as you go. You build over a bare work table, guided by a step-by-step photo-illustrated manual that walks every sequence from first frame to finished model.

Some Stevens Aeromodel kits include detail sheets — but these are reference documents, not templates. They show how parts relate, clarify key dimensions, and add context to the build. What they don’t include is parts templating. You could not reconstruct the model by tracing shapes from a Stevens Aeromodel detail sheet onto sheet wood. You’d never need to — that’s the laser cutter’s job.

“The parts themselves carry all the geometry. The laser cutter replaced the plans — it didn’t supplement them.”

The result is a kit that builds accurately in an evening or two, even on a first build. If you’re new to balsa, returning to the hobby after a break, or you want a rewarding model on the bench without a steep learning curve, a Stevens Aeromodel kit is the right place to start. The Ace (100) and Pacemaker (100) are excellent first builds at the ultra-micro indoor scale, or step up to the BuzzBomb (100) for a park flyer that flies at the local field.

The balsabuilder Way

A balsabuilder kit ships with a complete plans set — and “complete” means something specific here. These aren’t detail sheets. They’re full building diagrams combined with full-size parts templates for every component in the model. A skilled builder could take those plans to a sheet of balsa, trace and cut every part by hand, and build the entire model without any laser-cut parts at all. That’s not an accident — it’s the design intent.

The laser-cut parts in a balsabuilder kit make the traditional process faster and more accurate. They’re a modern convenience layered onto a complete, self-sufficient plans set. But the plans drive the build. You’ll work from a building board with T-pins, cut and shape strip wood stock to fit, and read the plans to extrapolate three-dimensional construction from two-dimensional drawings. The construction article guides the major assembly sequences, but the plans carry the geometry.

balsabuilder kits aren’t for first-time builders — but they’re a natural progression for anyone who’s built a Stevens Aeromodel kit and is ready to develop real plans-reading skill. Start with the 4Charlie for a well-documented 4-channel park flyer, or step up to the RV-4 when you’re ready for something properly scale. Browse the complete balsabuilder lineup to see what’s on the bench.
