First of all Bruce88123 there was no repair school part that I know of. This was all about getting solo in the least amount of time possible.
Skeeter the cost was 60 bucks an hour for flight time only. 30 bucks to check out your plane if you are bringing your own. I brought two planes out for him to check out and we flew both. However the second one was my Twist 150 and I wanted to log quite a few more hours on a trainer before I start flying this regularly. Roughly it cost me around 400 bucks total. That of course doesn't cover the gas, hotel and food. One thing I didn't mention also, I did solo the Twist after crashing my trainer.

It was my first ARF.
