Atlantis id thought about that, but it seem sall in the industry are made like that design, and yes it fires with 1 leg on it, the idea being that the flipper is long enough to not send a quick jolt but a long movement.
yes im on a tightish budget at the moment so cant spend too much
also whats GGDT???
whats a solenoid valve???
for the people that think this wont work, it does, iv esed them before, they are very fun and they dont break your legs, when first leaning, sometimes if you bend your knee to much you get hit in the arse and it hurts for a while.
im doing this from a begginers point of view, iv never used air pressure or made something like this so im still researching what exactly everything i need is =P thanks guys, the help is greatly appreciated
