Having 4 nitro planes in this day and age, you clearly have no limits!
Come to think of it I also have exactly 4 still, but only 1 has flown in the past 2 or 3 years.
Way, way before when I was flying every weekend I used to fly the heck out of my airplanes for months then I sell them, moving on to the next one, this is how I kept my skills sharp and my fleet small ( 3 or so ) now days like many of you, I don't have the time to fly that much, when I get a new airplane, I build it ( or assemble ) set it up and everything that is involved to get it going, it takes time and efforts and others have sentimental values that I frankly don't want to sell them and that's when the fleet starts to get out of control, a good example will be the Yellow Gee Bee, was given to me by a friend, complete, because of that I can't sell it, it was also the airplane that I was flying when my cataracts got so bad that I couldn't see it, that day it help me make one of the best decisions in life ( get the cataracts remove ) then there is my 27 years old Goldberg Piper Cub, I build that thing, sold it, got it back, rescued it nearly 10 years later and made her fly again, how can I sell it? and I can go on and on, all my airplanes have a sentimental attachment and that's why I won't sell them.
This is when it happened, at the Castle Giant event, it happens every May.
