Ralph N Bullock was a prolific and expert designer of 'all things modelling' This is a replica of his 1929 Wakefield Trophy winning entry. Construction is Hard-Wood, Wire and Doped Silk. It is quite heavy and relies on two skeins of 1/4" flat rubber driving through gearing just behind the nose block for power.

The original or the replica?
The replica climbing away on a low powered flight. The original had no 'De-Thermaliser' whereas the replica is fitted with a pivoting tailplane that is controlled by a timer.

This is his original model. Round The Pole (RTP) flying became popular during the Second World War because of certain restrictions being placed on the flying of (powered) model aircraft.
