I was concerned about that after watching the heavyweights at Maidstone!
But I felt I was better having an Ali frame supported by thick armour rather than a steel frame with thin armour. I will weld the steel armour together which should be the main structure with the frame just really being a guide.
And if it gets bent then it gets bent and I'll just re-build the robot- after all that's half the fun! I just want to get this version done so I can test it before going for a re-design as otherwise I would never get anywhere!
