The twin-engine transport that flew The Hump — the most demanding supply route of WWII — in giant scale.
The Curtiss C-46 Commando was the workhorse of one of the most dangerous supply operations of WWII — The Hump, the treacherous route over the Himalayas from India to China. Larger and more powerful than the C-47, the C-46 could haul more cargo at higher altitude, making it essential for supplying Nationalist China when all other routes were cut off. 3,181 were built, and many continued flying cargo missions in remote corners of the world well into the 21st century.
Kit Cutters supplies the precision laser-cut wood. This guide covers the rest: the honest, model-specific list of what you'll buy to complete it, with real sources for every part.

Model-specific, with real sources. The C-46 is a Bates design — a step up in scratch-building compared to the Ziroli warbirds. Cowls and canopy require building per plan. Everything else is well-sourced.
The C-46 requires TWO matched engines — one per nacelle. The plan specifies 2× .45–.60 two-stroke glow. Both must be identical. Modern builders commonly convert to electric twins for reduced noise and maintenance.

The C-46 used retractable main gear in the full-scale aircraft. The plan shows fixed and retractable options — most builders add retracts for scale fidelity.

Specs from Jerry Bates' published C-46 Commando 1/13.5 scale plan specification. Jerry Bates also offers a larger 1/9 scale C-46 at 144" wingspan — confirm you are ordering for the correct version. Check jbplans.com periodically as cowls and canopy may become available.
Jerry Bates Plans produces some of the most accurate and detailed giant-scale RC transport and warbird designs available. His plans are based on factory drawings and feature exceptional structural detail. Bates designs are known as more demanding builds than mainstream commercial kits — rewarding for experienced scratch-builders.
Get Bates PlansThe C-46 is a more demanding build than the Ziroli warbirds — twin engines, tricycle gear, and scratch-built cowls and canopy require additional planning and skill. It rewards experienced builders who want to tackle something outside the mainstream. Treat these ranges as a rough sense of scope.
Jerry Bates' plans include full-size templates for all structural parts. A Kit Cutters short kit removes the entire cutting stage — your ribs, formers, and nacelle parts arrive precision laser-cut and labeled, so you start at assembly rather than at the cutting board.
