colinhilton: CONCEPT TYPE

The target evolution of all that has gone before. The recent addition of a tail so (so that the spars are more fully reflexed along their length) would appear to have advantages in particular with types with more aerodynamic qualities, providing as it does a set of tail surfaces with powerful leverage moments and a better distribution of the centres of lift and of gravity. It will use a clutched propeller of the sort used by parameters in order that the craft will be able to hydroplane without auxiliary means.
