Kyosho Concept 30 Helicopter: History, Versions and Buying One Today
The Kyosho Concept 30 is a .30-size nitro RC helicopter introduced in 1988 and designed with Shigetada Taya, winner of the first FAI F3C helicopter world championship. It was stable enough for beginners yet capable of aerobatics, and became one of the best-selling helicopters of its time. Versions include the DX (bushings), the SE from late 1989 (ball bearings), and the later SR-series. Today it’s a vintage model: rewarding to rebuild, but parts are increasingly hard to find.

Why it mattered
Before the Concept, helicopters were often complicated and expensive to keep flying. The Concept 30 combined a simple, robust layout with good flying qualities, and Kyosho priced it within reach of many modellers. Its flybar rotor head made it stable in hover, which helped a generation learn. Many pilots who fly today learned on one, which is why it’s still talked about. The flybar system is explained in what a flybar is.
Design
- .30-class glow engine with clutch and cooling fan.
- Flybar rotor head with Bell-Hiller mixing.
- Plastic and aluminium frame, belt or gear-driven tail depending on version.
- Mechanical mixing on the swashplate rather than electronic CCPM.
- Tail gyro (originally mechanical-electronic gyros of the era).
Buying one today
- Check completeness: rotor head, flybar, tail, canopy, manual.
- Look for worn bushings or bearings, cracked plastic, bent shafts.
- Expect to replace fuel lines, glow plug and the old gyro and radio.
- New-in-box kits are collector items and priced accordingly.
- Find a parts donor: a second used Concept is often the best source.

Rebuilding and flying
A rebuild usually means new bearings, a modern 2.4 GHz radio, a heading-hold gyro and fresh fuel tubing. Some owners fit a modern governor too. Fly it carefully: plastic parts are decades old and can be brittle, and blades of the era should be checked for cracks or replaced. Many owners keep their Concept as a display piece and fly a modern helicopter instead, which is a sensible choice if parts are rare.
Parts availability
Kyosho stopped producing most Concept parts long ago. Sources are online auctions, forum classifieds, vintage heli specialists and 3D-printed replacements made by enthusiasts. Some parts from later Kyosho helicopters or other brands can be adapted with work. Before buying a project, list the parts you’ll need and check what’s actually available.
What it’s worth
Used flyers sell modestly; complete, clean examples with original boxes and new-in-box kits fetch much more from collectors. Prices depend on condition and completeness, so compare recent sold listings rather than asking prices before you buy or sell.
Concept 30 vs modern helicopters
A modern 450 to 550 size electric helicopter with a flybarless controller is more stable, needs no engine tuning, and has parts on the shelf in most hobby shops. The Concept 30 offers something else: the sound and smell of a glow engine, mechanical mixing you can see and adjust, and a piece of RC history. If you want to learn to fly, choose a modern helicopter; if you love the classic, enjoy the Concept as a restoration project and fly it on calm days.
FAQ
When did the Kyosho Concept 30 come out?
In 1988.
DX vs SE?
The SE added ball bearings where the DX used bushings.
Can I still get parts?
Mostly used, from collectors, or 3D-printed.
Is it a good first helicopter today?
No; modern helicopters are cheaper to keep flying and easier to learn on.
