I guess this is a good a place as any to ask, and I was wondering about how much tunnel time does it take on average to move through the different positions? I'm asking mostly for budgeting purposes as I want to get coaching to get better for basic RW and basic back/sit flying in the tunnel before I try it in the air. I know everyone is different, so I'm just trying to estimate how much money I'm going to need to throw down to get through this plan. Thanks!
