When I first got into carrier I thought the plane was 60%, the engine 30%, and the slider 10%. Heck I already knew how to fly, right. Six months later I thought the plane was 40%, the engine 30%, the slider 15%, and some practice 15%. A year later I thought the plane was 20%, the engine 40%, the slider 15%, and some practice 25%. Now the way I look at it the plane can be almost anything that flys, the engine and how I can get it to work for me is 40%, and flying it so that you know just how it will handle different conditions (practice) is at least the other 60%.
After the second year I knew I had to have Nelson engines because after I had them I could cross off what I should use for power and put my efforts into how well I could get everything to work while out in the middle of the circle. I have always been dismayed that the people I was flying with would say "Oh those Nelsons cost to much" and when I was out flying my carrier planes they were home working on one of their many engines that they had bought on e-bay or where ever and not getting anywhere but older in age. When you reach a certain age time is the most precious thing you have and for most of us that can very some but in the end (well you get the drift).
Now I fly my best carrier planes when ever I can, smooth take offs up to 10' altitude, 7 fast laps, slow down as fast as I can and get into the hang, 7 laps of slow speed, and one lap later I try to catch the one arresting line I lay out between 2 2.5 pd weights. I only catch the arresting line maybe 30% of the time but usually don't miss it by much and never under shoot by far. Life is good. Eric
