First off, I apologize if there is anything on this problem that I couldn'f find, but I didn't really know what to look for this, so:
Right now I have a 5ft tall drop in, but I haven't attached an actual ramp to the structure. I'm not sure how long the ramp should be to get the right speed. I've seen drop-ins with really steep angles and some with more mellow angles, so I am pretty lost. Again, the drop in is 5ft tall, and it is on the top of a slight hill. How long should the ramp be?
