Wiring up my weapon control, technobots twin relay got it set too oposite controls, ie ex open inlet closed
using my rudder stick but it seems slow and when link is in the exhaust opens with or without bec on, this is safe but is it correct
anyone post pics of there fire control designs

Send a negative feed to one side of each of your coils on the valves. Feed a positive to the two commom terminals on the switcher, the a wire from the NO terminal on one side to the fire valve and the other NO terminal to the valve on the other side. That way you use the stick one way it will fire, the other way will exhaust, middle will hold the arm where it is.

Thanks for reply all sorted and tested, full pressure gas test tomorrow

quick link to ceros flipper test, only low pressure was tested on a regulator due to no armour or bungee system enjoy

[plargen]

link doesn't work but manage to find it, what pressure were you testing it at

[adz600]

Not sure at a guess around 5-8 bar no gauge on the reg but was only cracked open,high power acl valves worked well,will test again with gauges etc after christmas

[mightymouse]

Was nearer 5-8psi than bar. the regulator was turned only until gas flowed - Expensive welding reg not one of my specials lol

Looks pretty cool mate

thanks for replys, looking at no toy soon what mod gears tend to be used for a speed 900 drive gear reduction
looking at about 4;1 gear reduction and 100mm wheels

So speed 900 drive
Speed 900 twin axe motors
22.2v lipo

will be fun, same problem as always weight

If you mean the well known Graupner Speed 900s at 6s, 4:1 and 100mm wheels, you're looking at a theoretical top speed of almost 40mph. I'd gear down a lot more. In most arenas you'll never really see more than 15mph, 20mph from one end of the heavy arenas to the other, perhaps.

If these are slower revving motors, say 4000rpm @12v or something, you're still looking at nearly 25mph at 6s.
