I am learning in an AS350 and did my first solo at 30 hours. This involved going into a hover for about a minute or so and then landing. I find the aircraft tricky to land so this was probably the most hair raising moment for me thinking that I was never going to be able to come down again (!) Coupled with this I was terrified of being alone, but this has got alot better as I was told it would. I felt the difference in weight quite substantially at first, even though we have alot of weights in the aircraft to try to couteract this. Have now completed just over 4 hours in the circuit and looking forward(!) to the first time outside.
I am very fortunate to have an excellent Instructor who never pushes me beyond what I believe to be my personal limits, that has been essential for my progress.
