Sportsman class is a very diluted feather class, mainly aimed at new roboteers getting into the hobby, first time builders, or for experienced roboteers to try out new ideas before implementing on full combat feathers.

For example our full feather class has a tip speed of 200mph, where as the sportsman is 20mph.
Armour on sportsman can only be wood or plastic, but not hardened steel etc..

we are wanting the vast majority of feathers to be full combat class..
