its already being produced :D
http://www.robotcombat.com/products/0-SABER2X12-RC.html

for a flipper you'll need a load of pneumatics including:
reservoir tank
buffer tank
solenoid valve(s)
adapters
quick release valves
tubing
ram
regulator

(probably missed something out there but thats all i can remember off the top of my head:P)

for an axe you could use pneumatics (i am for a heavy) or you could use an electric motor like pure evil. a motor would be easier (probably).

an as for lifter you need a powerful electric motor like a windscreen wiper motor from a car. (panic attack used 2 heavy duty lorry windscreen motors). or you could use a drill motor hooked up to some type of hocus pocus mechanism. (harry tried to explain this to me but i can't remember :roll: ) so you'd be better off asking him, his forum name is 'haz'.

Two issues with that:

I: They're still considered 'spinners' and so have all the issues associated with those (i.e. being only able to run twice to three times a year with the weapon, safety, a couple of extra rules)

II: Saws, generally, are designed to cut slowly into static wood or metal - robots tend not to be very static and not precise enough to cut slowly, and even if they're used 'correctly' they cause minimal damage, especially to modern armour - if you stick a wood cutting blade on a motor and ram another robot with it, it'll almost certainly shatter or break or otherwise cease to work.
(hardened steel wood cutting blades are also banned by the way :P)

Pussycat's blade from series 4 onwards was much more of a disc than a saw, it only had four teeth, was specially engineered and did most of its damage from inertia and impact damage.

1st of all have you grub screwed the drill motor? if not look up a guide or ask someone how to do it and then do it. you need a speed controller to turn stick movements into motor movements as discussed previously on this topic.

Bought my second motor today but in having trouble attaching the wheels properly, any one got any ideas of how to attach the wheels to a shaft of a motor?

It is probably stupid but I doubt strong super glue would do it? :)

For wheels with a hole smaller than the drill shaft diameter you drill it to a slightly undersized hole and using brute force screw the wheels on if they're made from plastic.

You can put a the reverse thread screw back in with a washer for extra security.

For larger holes a plate that screws onto the drill shaft and then boltsto the wheel could work.

What wheels have you got? so we can try to give you a better solution than the ones above.
