How tall does a drop in have to be for a summer setup?

depends on what you use to slide on.
how steep is better way to phrase this ? but i maybe totally qrong bu w/e

tell me.... how tall the box is....if its on a slope or pretty flat.....if the in run ramp will drop to the ground then come back up or go down the whole time and drop onto the box....and if its carpet powderpak or ice rink snow that ur usin and ill give you my best guess

like a foot high box, carpet, goes down then a jump back up

& pretty flat

hmmmm well my drop is 9-10 feet tall and used a carpet wet down with soap and there wasnt enough speed for a 14 inch tall box which was on flat. if you make it so there the drop but it never goes back up so its down steep then curves but is still goin down or at least levels out but never really goes up then you dont loose speed. you have balls of speed coming down the ramp then loose it all coming back up the jump. make it 8-10 feet tall and have it never really go up. then have the rail a little under the lip and have it be slightly down thatll make sure you have enough speed and height to spin on slide it to the end etc. espec with a box you need lots of speed

my friend and my summer set up is 20 feet long at times 28 when we extend it and so far we have been stepping on...so the drop in doesnt need to be enormous mabe like 4-5 feet

or i could make a really small box like only 7 or 8 inches high

my dropin was 12ft tall, and I have a decent hill, and I got too much speed for a 2ft high rail... and this was on carpet with no water or soap.

i have a 6 foot tall drop in with green turf and that seemed to work really well, and my rail is 16 feet
