[NRVR-Members] DIY Rail Pad

Must have missed this reply Bob.

yeah.. I guess I see what you mean.  The only thing that really ADDS to the stability it getting the legs as far out as possible (so flat represents the biggest "reach").  but you're right.. in a non-flat world.. flat can be a problem.  Maybe a shallow 10-20deg downward angle makes the most sense.  Sort of like what Estes did with their plastic launch pad's flatter profile design.

I bet it wouldn't be hard to modify this pad design to instead of swing out horizontally, to swing down vertically and lock into position. :)
