Lets have a think...

3x Heavyweights (+2 internal rebuilds of UFO & Knightmare)
16x Feathers
2x Middles
19x Ants (at a guess)
Plus the 6WD all terrain bot i built for a company

I sure theres some ive forgot. I have no idea about the amount of fights, i know the first 2 Merlins did about 80 fights each.
