    Co2 Powered Drop nozzle

    I had the RnD Drop nozzle on my RXP and its a awsome piece of kit for the corners and haldeling in general, its only down fall in my application was that I didnt have VTS and so to stop it jumping out of the hole I had to run the trim quite low all of the time which was costing me performance, so I decided that I needed manual control so that I could set the nozzle for best speed and still be able to drop the nozzle out of the hole.

    First off I set it up using a cable all the way to the nozzle from a leaver on the bars, this was not so succesfull so I set about making a Co2 powered kit I made it all myself, its fairly simple really but workes really good I just need to go and do a few holeshots to get the right amount of drop dialed in.

    Basicly I still have the leaver on the bars which pulls a cable to operate a switch whichs fires a relay then the soloniod valve. Im using a Paintball canister which holds around 1000psi and has the regulator mounted to the bottle. Currently it is set to 150psi but Im not sure how much pressure ill need to run to keep the nozzle down.
    This is obviosly not an issue for people who have VTS but mine hasnt and this setup also reacts alot faster then the VTS does either on or off as well so no trying to get the VTS set right when racing.

    Hope you like R88

    Cool idea..

    Why not use tunnel pressure to control it? Vacuum @ launch and rising pressure @ speed.

    I looked at that and had 2 reasons against, I ride in salt and flushing out the system would have been complicated, and second im fortunate to have a certain amount of materials at work that I was able to lay my hands on but we only have pneumatics.

    Dan's isnt Co2 powered its hydraulic. Not sure where he got it, but I think he told me the UK. It's much easier to pull than the Skat-Trak Cable even at speed for sure when I got to ride it.

    Just needs a mini 12v compressor to keep the bottle full, bottle used for volumn storage.

    Mine is real easy to pull ass im only pulling against a throttle return spring in the control box, I guess with Dans tho you have some control of the movement where as mine is either up or down but then I have the auto drop fuction so dont have any real need to use trim once running.
