This model was originally built by my father in the 50's for i.c. power. it was laid up in 1962 and remained inactive until two years ago. At that point, I egan recommissioning it, fitting twin brushless motors in place of the deafening single glow motor and straight-cut gears. I also added a great deal detail that my dad had never added. it performs very well nicely in this guise with the added drama of a throttle-linked digital sound system. (5/10)
