CeeGee, I wouldnt worry about it too much I am the same as you. I fly warbirds most of the time and i just love to punch holes in the sky flying round and round in circles and doing low passes. I did try to do a loop on my T-34 mentor and everything went wrong for me (I wish i had brown pants on). i started the loop and got just over half way when the plane snap rolled on me and it started spinning towards the ground. I had a very experienced pilot standing next to me as my spotter and was telling him i had lost it. with maybe 20' to spare i managed to pull out. I guess i never had enough power going through the loop and lost all lift.
