Re: Technical feather stuff

It costs £214.02 if you add the £7.50 P&P & the VAT. How much would a custom one cost?

Depends on size, but less is a fair remark.

Not that many people willing/capable to supply custom FP rams tough.

Where could I get one from?

I stumbled across this lot yesterday and they seem to be fairly decent with a nice 16 bar pressure maximum. Bore and stroke isn't too shabby either. They are a tad on the heavy side by the looks of them though.

Re: Technical feather stuff

Thanks, but their pressure limit, 16 bar, is low. I need a higher pressure ram.
Does anyone know where I could get an HP pressure relief valve?

Ok, one thing is still bugging me; how do I failsafe everything?

The pneumatics? You get an radio controlled switch & wire it up the valve solenoid as shown in the supplied diagram.

Pretty much anything that has a servo lead has an built in fail safe, with some very aircraft based exceptions.

Re: Technical feather stuff

Thanks, but not just the pneumatics; everything. Is their a controller with failsafes?

Most speed controllers fail safe.

Electronize, Scorpion XL & Sabretooth are the most common found in FWs.There are other boat controllers out there that do also but are designed for,well, the current of boats. I'd recommend Electronize to anyone, not the best but simple, doesn't break easily & cheap.

For the pneumatics, try technobots own RC switch or the Battle switch. Both will fail safe the system.

Ok, finally, I just have to ask this:
Is this all I need, and will they all work together?

Re: Technical feather stuff

you'll need a solenoid valve to control the cylinder and an on/off valve.
also the tank is really expensive inc postage the bottle in front of me is the same size but half the price

Re: Technical feather stuff

plus you will need a battleswitch to the valve
