I forgot to add the regulator to the list, because mine has been attached to my bottle since I got it ![Razz :P](./images/smilies/icon_razz.gif)

trevors regs (lightest option, used by most lp featherweights) is only £40Duff wrote: And don't forget you'll also need a CO2 regulator, which will cost a small fortune!

Re: EEEEEEEEEEEEEEEEEEEEEEEEK
found this intresting bore ram on the FRA forum

the valve you suggested

Re: EEEEEEEEEEEEEEEEEEEEEEEEK
for the ram i'd suggest you aim for a much higher bore! more bore=more power
that co2 cannister has a pin valve. basically that means that co2 comes out as soon as it's attached to the robot, this type of valve does not conform to the fra rules:
[quote]9.6 Remote Isolation Valve Gas cylinders that do not incorporate a valve (for example: the gas is released as soon as the cylinder is screwed into it‟s mating pneumatic connection) such as found on disposable welding bottles and „fizzy drinks‟ machines must have an additional remote isolation valve accessible from outside of the robot./quote]
you can use that bottle but you'll need an adapter like this:

Re: EEEEEEEEEEEEEEEEEEEEEEEEK
so basically i take off the pin valve and attach that one.
would you be able to suggest a bore ram![Confused :-?](./images/smilies/icon_e_confused.gif)

Re: EEEEEEEEEEEEEEEEEEEEEEEEK
Seriously, don't do it. You put up one of these over-enthusiatic posts all the time. It's great that you're enthusiastic about building robots, but you really need to start at the bottom and work your way up. You're trying to walk before you can run and it will only result in a waste of time and money, if not serious injury. If you've never built a featherweight before, make a 2-wheeled rolling platform to teach yourself the methods. Pneumatics are complicated and dangerous and its clear you have no idea what you're on about with them. The way to learn here is NOT through trial and error, especially at your age and experience level.

Re: EEEEEEEEEEEEEEEEEEEEEEEEK
im not over enthusiastic.
i just want to make a robot that is quite good.
not something rubbish.
plus i have loads of advice from you guys.

Re: EEEEEEEEEEEEEEEEEEEEEEEEK
no, the pin valve screws into that adapter. then when the wheel at the top is turned the pin valve opens and co2 comes out.
ram wise i'd suggest having a bore greater than 40mm for low pressure.
i'd suggest:
http://cgi.ebay.co.uk/Festo-Air-Cylinde ... 197wt_1141
the volume of this ram is a quarter of a litre, for a buffer tank i'd recommend going for triple that.

Re: EEEEEEEEEEEEEEEEEEEEEEEEK
i kinda agree with dave, heres a suggestion:
build a basic featherweight rambot and learn how these larger weight classes work. if you still want to build a flipper you can use drive and batteries from your rambot in your flipper
by the what budget are you working with? featherweights are alot more expensive than ants!

Re: EEEEEEEEEEEEEEEEEEEEEEEEK
You can build a perfectly good featherweight without resorting to doing something you know nothing about. Look at Tiny Toon. Basic, 2 wheel drive pusher and its won a ton of events, including, at one point, the title.im not over enthusiastic.

It's a classic mistake to overstretch yourself because you want to win, or have a competitive robot. It's also not the best attitude to have for a project, especially with the level of quality and experience of featherweights out there. It is incredibly hard to win a featherweight fight, because there are usually about 20 robots in the ring at once. And what makes a "good" robot is open to interpretation anyway. Personally I think having yet another pnuematic flipper would not be a "good" robot at all.
With your level of knowledge, you'll never build a pnuematic flipper thats going to compete against other feathers out there. You need to gain knowledge and experience before attempting something like that. But, by all means, if you want to ignore practically everyone's advice on here and do it anyway, go for it. We can only say we warned you.
