Right well I?m just curious as to what interest people might have in this, but I have taken one of my RGB traps apart (I managed to repair it was damaged)… and have been able to replicate the air peddle system (on paper I am going to build a test prototype? if any one is interested I can post up some pictures for you guys to look at? of both the prototype and the actual RGB mechanism
yes please do the concept of an air pressure system for a trap prop is waaaaay better then wireing up a buncha servos and batterie compartments 
that would be awsome. ya know what i was planning on doing for a rgb trap peddle? i was going to but one of those “easy buttons” from stapels, sand down the top where it says “easy”, then drill a hole in it and attach a pnuematic connector to it for the hose.
I’d definantly be interested.
I would like to watch this… I’m working in a prop for my nephew… and it’s not working as I thought.
This thread is from 2006, not much here to watch. :sigh:
keep ur eyes pealed!
