Summer setup help

yea, that should work.  But a rail would definitly be better.

If you don't have enough speed then move the jump so its actually on the hill, that way you don't have to go all the way down and back up.

Finnaly, i will only use the natural drop. That's what it look like after 20 minutes.

Ok i start wokinbg on it and i decide to remove the drop in (see previous pic) and use only the natural drop. Results: I try it without water i was not getting over the jump. I think I will add 5 feet of drop.

+ I built a 10 feet rail

Here is what my setup look like now:

When I try it

Overall view (the drop-in is about 8 feet long

 10 feet rail (6 inches wide and I will cover it with UHMW or something like that)

Takeoff (about 14 feet high) (the rail look higher but it is because nothing hold it)

Takeoff= not 14 feet high but 14 inches high

Sorry

When i try it first time no

Does it affect the speed alot?

because i really need more

You are wasting your resources.  You built the ramp and just layed it down on the natural slope.  What's the point?  Bring the ramp up so that it extends the natural slope.  That sould give you what looks like it would be about 25 feet of run in on about a 20 degree slope.  That should be more than enough.  The other thing that works well and sometimes too good is bio degreaser or bio friendly soap.  Dilute that stuff with water and spray down your turf.  It will be way fast and you may have to throw in a few speed checks to keep from disastering your whole box.  I bought my biodegreaser at Ace Hardware.  It's for degreasing bike chains etc, but it won't kill your grass when it drains off.
