After the success of the Concept 30, Kyosho moved on to developed its bigger brother.  They went straight for the 60 market with the aim of introducing the Concept 60 as the model to be beat in its class.

Upgraded over the standard Concept 60 with many new features: no-slop push-pull cyclic linkages. Tail rotor drive shaft support along its full length to prevent shaft whip. Gearbox sealed against dust. New metal parts for extra strength in the rotor head. Choice of flapping or see-saw for even better aerobatic flying performance. Composite-structure main rotor blades, with leading edge weights to move the blade C of G to its optimum position.  New, stylish and crash-resistant LSS resin moulded body.

The Championship version upgraded the 60 SR with advances developed by master pilot/designer Kazuyuki Takayanagi - including stainless steel tube drive and bearing for more precise tail control. Top it off with the optional Interceptor Body shaped to improve forward flight speeds and aerobatic handling.

Kyosho Concept 60 SR II

 

The SR II was the last variant of the tried and trusted Concept 60 released by Kyosho. Modified to comply with new F3C competition regulations and included parts that were formally only available as options. Starting from the top, the new main rotor shaft had slots cast into it which help prevent the revised mixing base from twisting in flight, thus reducing the risk of lead/lag changes. The flybar was strengthened and the flybar paddles were larger to give increased stability and manoeuvrability in flight. The transmission case and lower side frame designs were revised and strengthened to increase service life! The new feathering shafts (spindles) were scaled up versions of the Concept 30 type. The larger hub offered increased strength when running at higher head speeds and through tight aerobatic manoeuvres. The counter gear, gear housing and bevel gear were all Zeal items. A strong and lightweight carbon fibre tail boom replaced the original aluminium boom and the original wire type tail drive was replaced by the pipe type tail drive system; so there's was no risk of the tail 'winding up' under load. A clutch and fan collar to suit the OS 61 SX-H helicopter engine was included as standard (an OS 61 SFN-H combination also available). A new mark deserved a new look and the SR II sported a modified fuselage with new decals.

Kyosho Concept 60 Upgrade

Despite being developed to as high a standard as possible and by the SR II version there was nothing much that could be improved there were still a number of upgrades; even if some were no more than cosmetic.

Concept 60 Z-61 HP Flapping Head - Zeal 'official' upgrade for all versions of the Concept 60 and as per the Concept 30, incorporated a connection between the two blade holders so that as one blade flapped up, the other flapped down.  Similar principle to the modern 'feather' shaft system.

Concept 60 HP metal frame set - Zeal 'official' upgrade for the Concept 60 SR version and improved the 'stiffness' of the frame thereby preventing unwanted twisting during harsh manoeuvres.

Kyosho Concept 60 Scale Fuselage

Despite being primarily designed as an out-and-out performance model, being of pod and boom construction it did 'lend' itself to being fitted inside a 'hang-on' fuselage; enter the JetRanger body kit.  Basically an enlarged version of the Concept 30 body though it did look good and of course had excellent handling properties.
