as a foward hinge flipper robot owner i can add my 2 pence worth. i was vacant from the robot scene for a while and when i decided to come back i built envy from what robot bits i had left on the shelf. dur to the size of the ram i decided to do front hinge flipper. it took 3 attempts to get the design i was happy with but in the end i think i now have a potential championship winning robot. in the 07 uk champs envy had 4 fights and ootad 5 robots. envy did have design flaws and 1 or 2 minor drive issues but as a front hinge flipper i was well pleased and will be keeping the deaign and shape the same. i am also just building a front hinge feather called envious which wiull be on the circuit shortly.
