The Concept_30 was introduced in 1988 but quickly established itself as one of the best selling helicopters in the world and for a good reasons; it had the stability needed by beginners, yet it could perform aerobatics with ease. However, that was not really surprising since it was designed by the first world FAI F3C Helicopter championship winner Shigetada Taya.

The design brief was to produce a helicopter that would suit both beginners and experts alike; not possible of course with a single machine.  However Taya designed a machine to suit the experts which had good control then basically 'detuned' it for beginners by utilising heaver flybar paddles.  The model was also supplied with two tail rotor types; the normal holder with bearings or a 'bearingless' type; additionally to reduce cost the number of bearing in the models was reduced from 31 in the SE to 18 in the DX.
