ive had a basic rammer, and something with claws (shame they were crap) but once ive got smidsy up and running im really wanting to build something with a good active weapon yet i really cant decide what too do
i was thinking of going down the crusher route again as ive really got a thing for them, but trying to make a crusher thats invertable AND will also crush either way up is a bit hard
im open to and suggestions as im really quite stuck for a design
i'm building a crusher to but if you want it to be invertible i'd say go for a horizontal crusher because to get a verticle crusher to work invertible would be nearly impossible
made a horizontal already with masses of design flaws
not sure if to try and re-build that to scrap it and make something different
Any other ideas as after whitwick I'll be building for the champs
If it's for the champs then build a spinner
Finding a disk that's a good weight is hard, but I would like to build a spinner, just cash would be the problem there
Then forget a disc and buy a stainless steel bar (first thing i came to searching ebay)

Drill it in the center and go to town. Job done.
Gary, you are a genius!
Spinner it is I guess
Got a spare pair of esc's, need a couple of motors and bar set up but it shouldn't be too hard to do in time
If you want a cheap motor, go for a car fan motor (Mondeos seem a good source). You can pick them up from car breaker's yards for £5 - £10 and they usually do around the 1hp mark. DragonStrike is the best example of putting one to use on a spinner.
And if you go for a bar, make sure to get the drill hole dead centre, otherwise you'll wobble yourself to jiggery!
Can I be a real pain and get someone to post a parts list and rough cost to make one?
kinda just got one matt, normal fw parts plus bar and motor (with some belts and timing pullys etc)
And ESC for the bar ;) lol
there you go, you've done it yourself :lol:
If you go for a car fan motor (or even Speed 900s) I'd just go for a battle switch/relay combo. Spinner ESCs aren't really necessary (brushless stuff aside) as most of the time you'll be running at full speed anyway. Just easier to flick a switch and enjoy the buzz of it spin up :)
Don't be surprised if the cost of things such as pulleys, belts and various washers and/or fixings needed for a spinner is more than you might have expected. With my first spinner I spent a fair few quid on things I thought I'd need but didn't, or didn't use because they weren't quite right for the design. A good degree of planning can help but trial and error plays a big part.
So current list is:
Box frame chassis
Polycarb armour
2 drill motors
Set of wheels
15a ESC with 30a fuses to run 18v
18v Nimh pack
Fan motor
Stainless steel bar
Relay/ESC, what ever I can get
2 pulleys for 1:1 ratio? Not sure yet
Belt
Various bolts etc
All sounding good?
Sounds fine. You will also need a shaft and bearings for the bar. I'd recommend a shaft of at least 17mm diameter silver steel or similar.

These would do for timing belts/pulleys for the bar. Make sure you get a spare belt or two.
You can go for the box section construction if you want but few feathers go that way. Instead the monocoque is prefered. You've got a number of options but the easiest to make is a plastic based one. Nylon for structural bits and pieces.
Cheers Gary, forgot about that
I've got enough for armour, spare esc's, metal for chassis
So I need some motors, wheels, batteries and the disk set up. Should come under £120 if I shop right. This will probably be a one event spinner just too see how it goes
even at the worst, it should cost £140 to build the spinner
if i can sell enough of my crap that i dont need then it should be achievable
What escs are you using?

electroize or what ever their spelt like :lol:
do you use the fuse to make them higher voltage?
nope, just add a bigger fue in he 15a ones to decrease the chance of it blowing
thats cool (and helpful)
