The model

The Peanut Scale model appears to be based on the Bell-Hughy 'Cobra' - a slim machine, well suited to modelling (our radio control compatriots used the 'Cobra' in the days when R/C 'chopper' flying began).

It uses simple rubber power, but unlike the traditional direct drive 'stick and rotor' duration models, has a gearbox to divide the power between main and tail rotor in the correct ratio.
