Damn,

Yeh that is never going to end well going beater into blade.

Wedge on the back should have been utilised then beater.

It looked to be going well for the first couple of hits anyway.

Beaters work well against horizontal spinners though. 3PD had significant amounts of wins again horizontal spinners. The beater works well because it gets under the horizontal spinner without getting hit (compared to a drum) and throws the horizontal spinner upwards (Also works well on vertical spinners where the beater is lower then the vertical disc and hits it upwards (Misfortune V Demon)

Generally, beaters lose to a horizontal spinners when the bearing supports are not up to scratch and allow the beater to fall out. Sir Loin V Last Rites and now Miss Fortune V Sloth are good examples.

Yeah bearing supports weren't exactly designed strong enough to take a direct hit right on the side of the beater, hence why i had designed this version with a wedge.. most horizontal spinners are heaps unstable when their centre of gravity is tilted slightly so pretty much just needed to nudge them watch them fly helplessly through the air then go in for the kill while weapon isn't spinning.... well that was what i was hoping for anyways.

hopefully he learns for next time, also seems that the high strength properties of the bis400 have been rather lost through the oxycutting and welding :\ as he quoted "bashed it all straight again" Confused

lol yeah well every style has its achilles heel, the drum and beater style is the flat open supports at the front that are weak. But overall probably the most effective spinner style Smile

It's true, even at beetle scale on Carbine the flat open front supports (where i even doubled the material thickness) were bashed open by sustained horz. spinner attacks.

its easy to defend the sides of a beater, put a block of wood over the supports.
worked fine for Plan-G Vs Scissorhands.

bar spinner hits wood, makes mess doesn't bend the frame.
best part is your beater is going to keep spinning ;->

Wood makes quite good ablative armour, but you need plenty of spare weight to fit it. I can't help thinking that there is a better option, probably involving kevlar and laminating - the Riobotz team use a metal and kevlar layered armour in some of their bots

I actually was thinking about this earlier yesterday and had decided that some horizontal supports rather than flat vertical ones that then either curve or via a series of angles come back around onto the same angle as the side panels

would make the bot much wider though. From memory i think Mini Mower is designed in this way?
