A historical Time-line on Caliber Helicopter family

Kyosho did a splendid job introducing the Caliber to the market in late 90s. Started with the original Caliber 60 to replace the aging Concept 60, soon followed by the short lived smaller Caliber M50, which was available to the Japanese market only. The beginning of 2002, Kyosho offered the new Caliber 30 and 90 to the market with success.

Five years after M50, Kyosho introduced the 50 class coined Caliber 5 in 2005. The same year, Caliber ZG, based on Caliber 90 with a Zenoah G260PUH engine for aerial photography was released.

The entire Caliber family received an upgrade in 2006. A complete a redesign, most noticeable was the one-piece flybar and using some components from Caliber 5, the Caliber 30 was renamed to Caliber 3. Caliber 5 received a metal head treatment and branded with a M version. Caliber 90 also received a lower carbon frame enhancement, larger 600cc fuel tank upgrade and 140 CCPM support, renamed as Caliber 90 ’06 version.

Being introduced in 2007, the Caliber 4 was an upgrade to Caliber 3, featured a complete redesigned servo frame plus replaced plastic bushings with ball bearings. Caliber 6 replaced the 5 in 2008. The larger fuel tank replaced the header tank and tail got a push-pull tail servo mechanism.

Kyosho also released some completely assembled, ready to fly electric RC helicopter models, ranging from Caliber 120, 400, 450 and 700 respectively. The time of writing, these models are still being sold by Kyosho and will not be discussing in this article.
