    Felt i have been lurking here long enough and thought it was time to contribute.

    I designed and built this folding ramp to have both a 45 and 60 degree launch position and it uses a 3ft radius. I am quite happy with it's performance so far and have manged my first ever backflip off this ramp on its first outing.

    The ramp is constructed from scraps I had lying about: 3/16 ply, 1x2, 1x4, 1x6. It measures 31"x33"x5.5" folded with usable ramp width of 32"

    Nice work, thanks for sharing. How do you get the legs to stay in position? Is there a lock of some sort??

    To keep it adjustable and light i used some string. In the second picture you can kind of make out that the string is wrapped around a screw just off screen left and right, in that position it is a 60* launch (3rd pic) but if take it off those screws it drops to 45*(4th pic). Additionally, to fold the ramp i simply pull up on the string.

    Ah yes, now I see it. Good idea, much simpler than I was thinking.
