Re: Hard Time's build diary

How much (roughly) is a 63mm bore 75mm stroke cylinder meant to weight?

Re: Hard Time's build diary

I've had a few problems with Laser and we are going to change the 1.2mm ali to 4mm steel on the lifter
we have also changed it from the Planet to the spektrim as the reciever has broken.
The Sabertooth is still being a pain by randomly spinning or going the other direvtion to what I tell it to do when i put the stick staright into full forward.Any Help?

As for Shadow wave we are going to buy a regulator and a 20oz main tank and a few pipes and valves to get the pneumatic system going.
We are going to run it on 14.4v with 2x 12v deWalt d907 via a scorpian XXL
Where can I get a 12bar PRV?
also which valve would you recommend out of these three?:

Those valves have very low flow rate

Re: Hard Time's build diary

Thanks Alan I'll use that valve instead, but where can I get a solenoid to activate it?

Re: Hard Time's build diary

anyone?
also what is the max pressure that the valve will take?

[jonny]

Re: Hard Time's build diary

Max pressure is 7 bar

Re: Hard Time's build diary

ohh dear.. I wont be able to use that valve back to looking at the valves above and maybe some burkets.
