Back in 1990, Radio Modeller magazine published a plan for an attractive, low wing aerobatic design of 60″ wingspan, suitable for .40 two stroke power, designed by Colin Dickinson. The model was called Ruhig Tigre (which roughly translates as quiet, or peaceful tiger) and proved popular. In 2015, Jim Newberry took the outline of the Ruhig Tigre, increased the wingspan to 72″ and comprehensively redesigned the structure of the model to take advantage of modern laser cutting techniques.
The great flying performance of the original has been improved upon in this larger version and construction has been simplified by the use of interlocking parts which help to ensure that construction proceeds swiftly, easily and accurately.
Flight characteristics might be described as “sports aerobatic” – this model makes a perfect follow on for the flier who has mastered an aileron trainer and, with its thick symmetrical wing section, the Tiger 72 delivers a fine aerobatic performance.
