Do you think I'd get away with the Scorpion XXL it does 20a
Just read the last post, I'm fine!

I dont understand why you want to use an XXL so much when the Victors on here will be cheaper and running much, much further away from their limits? Also, I had a faulty XXL that used to go into its safety type mode all the time and you just loose all movement and the motors twitch on and off every second or so, you probably want to avoid doing that. I also thing the old XXL's had a higher current handling if these ones only do 20A, I think mine is rated at 25A.

When I was asking around people who use the Golds I was told to look for something around the 30A mark for ESC's

I have a strict budget, ideally I'll get victorss, but I think a single Scorpion XXL would be cheaper, since I would need two Victors. Also, 2 q's:
1. Where do you get ball castors?
2.What sort of pressure do featherweights use, my tank is welded from submarine steel, and in theory should do 50,000psi, which is crazy, the main problem would be the seals popping out!
Also, I found out the checkerplate is 4mm, is it still OK?
The plastic is from the base of a windows, by the way. It should be up to the job, I couldn't snap it, nor could my father.

Dont know where you're getting Vantecs from, and they are dual channel. The Victors I linked you to are cheaper than an XXL, and thats for 2 of them so i'm still not understanding your logic.

1. Got mine on ebay

2. 1000psi is the maximum allowed, but you need all sorts of certification to run that, speaking of which, I believe there is also rules on what tanks you can and can't use but someone else will have to answer that one really.

Sorry, I meant Victors! They stated 65pounds each, so it would cost me 130 pounds. Also, I wasn't planning on running anything near 250psi, I was wondering what pressure I should use. I'll fix my post!

Window plastic i think is PVC, it will break very easily, its far too brittle and thin. You can get ball casters from RS, ebay, technobots etc.

I I bent it about 30 degrees with all my weight, I doubt it will snap from pressure and it is about a 1.5 inch crosssection. It is the thick type, for windows that slide open. I'll check about PVC, if so I'll try and find something else, its no use if it snaps off! In the meantime, does anyone know what sort of pressure Featherweight flippers use? I'm thinking around 150psi?

All depends what system you are using. If your going low pressure (off the shelf stuff) then your looking at 10bar (145psi), which is what i suggest you do. If you go full pressure your anything from 250-1000psi depending on the temperature, but that then needs custom rams and hydraulic pipes/fittings.

[roketrhino900]

I might go 200psi, the stuff I'm using is industrial, submarine steel, steel reinforced rubber piping, which are 50,000 and 500psi respectively. I don't have anything else yet, but I'll get it to them pressures. Everythings to be strapped down with steel straps. Thanks again.

the problem with pvc is it's too brittle. i have a 1.5m by 2.5m 3mm sheet of it in my shed.
