Hornet 2 never used one of the hardox 650 discs. I got hornet 2s discs custom made by JL steel services from hardox 500. Got two plasma cut and sold one to Ed which Dave buggered up with 360 a while back.

The second one I cut a tooth off and rebalanced. From memory they were 12mm thick and I designed them to have the majority of the weight at the end. That was why hornet 2 was sold deadly. Well that and the magmotor!

I'll need to get around to rebuilding hornet 2 at some point. Brushless plus lipo would make that a fun machine!
