540's and 360s base didnt flex at all Dave- your thinking of beta- that flexed the battlebots floor- not the robot though.

Magnets in a pusher if used correctly could be a total game changer. I tried it in 540- when it worked it was a total beast… but the combination of 6wd, large wheels and a huge magnet (giving the robot an effective 40kg downforce if i remember correctly) was too much on the dewalts, i changed to speed 900's and custom gearbox's- but they failed too.

good example here;


It drove like it was on rails, no oversteer at all, no power slides, if another pusher tried to nudge it- it may as well of been hitting the arena side wall… Magnets in a pusher could be awesome- if done correctly.

If i was to do it again id probably use 4 off RS775 banebots kits, a big magnet in the centre, square wheel base and as for tyres i wouldnt bother… id just use solid aluminium wheels with no rubber on them.
