i did consider the snail style drum, but havent really got access to a mill with the exstra axis on to make it possible to machine... so im upgrading from ali/stainless to solid titanium drum with hardox teeth T slot'd in... hopefully it will hold up and not wear too quickly! do you find more success with the snail drum or the mushroom cloud style?

I saw a picture of how the new one is constructed with 2 semi circles creating the outer shape of the robot and supporting the drum at the front and bolted together at the back... real nice! i did consider building 720 in the same way, but i didnt like the thought of having all the internals bolt down onto the base plate rather than an internal bulkhead... too many axe's here, so i had to engineer it with an air gap top and bottom to prevent things getting damaged...

Yeah i saw that robogames has gone... such a shame... and yeah going to rio would be awesome lol id love to come over there at some point depending on costs and persuading someone else to go with...do you live far from the venue? if not id probably ship 720 to you...

Allthough i think team riobots should sign up for next years uk champs and come get some real competition! lol
