I think we might have about 10 feet of verticle, there are two sheets of plywood for 16 foot run into the transition and another 6 feet in the tranny and lip.
I would guess the lip is 2 foot of verticle. The gap is over 30 inches and the rail is 18' long. Nips was landing in the middle of the rail. so we are changing the set up by regrading another in-run next to this one. it won't be as steep and will be just a flat rail installed level.
