So you spoke to a trainer / instructor
.....he said training would consist of 7 to 10 days and to me that sounds like it will be rushing and throwing me into the air and calling me a pilot.
In an earlier post you said
..I could save $1,500 to $2,000....
It sounds like you've already made up your mind.
Bear in mind that there is a big difference in participating in a sport and being able to teach it in a safe methodical manner.
There is no correlation between learning this sport and anything else you've learnt or taught so far.
My attitude was simply - when something goes wrong, as it does with any ariel sport, I want to have the skill set and knowledge to give myself a fighting chance. For me that could only be gained by proper structured learning.
Good luck !
