    It was stupid fast! Loved it.
    We are currently redesigning the leaning mechanism to use mountain bike rear shockers instead of the trampoline springs

    Thoughts have turned to next year..... Planning on using the same body but with a modified chassis...

    Tonight I built it up and checked for damage. The body mounts were twisted but sorted that with a hammer and adjustable spanner. Unfortunately the roll bent the upright on the back end that everything is welded to... Body gonna have to come off so I can bend it all back straight

    All 4 wheels off the ground... I count that as serious air!
    That ramp was mental!

    How steep is the course after the ramp compared to Rotherham Paul?

    Steeper than Rotherham mate.

    Body off and chassis stripped. The toll twisted the frame at the old pedal crank bearing housing. Warmed it up and tickled it with a hammer. It's OK now.
    Found loads of straw in it for some reason. No idea where it came from....

    New lean mechanism is underway, sacked off the trampoline springs. New method is rubber blocks :) hoping to mount a bracket inside to fasten a smoke discharger into

    Bought some air blast air fresheners to use... Will look better than a smoke grenade, may give some thrust whilst smelling like cherries :)

    Couple of old CO2 fire extinguishers?

    Thought about that but a 2kg extinguisher only gives 20-30seconds of flow

    Modified lean mechanism, small compression springs inside sleeves of old bump stops. Will give a progressive lean and a positive stop... Hopefully
