Very very small number...... and even then they have not fully optimised themself to do so.

I was a big fan of them adopting the F16 concept and raced in the first F16 Nationals in Australia about 3 or 4 seasons ago...... But a very large majority off the Taipan class and members are not interested, so that is where it has ended. The standard 4.9 class is doing very well over here.
