I can’t remember where I got that pic, had it a long time. I have it on my computer for my home page. I built models for years and love WWII vintage fighters. Years ago I built an RC F4U 36” wingspan, it’s a beauty and my grandson still has it.
About a year ago I had a Comcast tech out for an Internet problem and he asked me if that was me flying it, I told him no because if I get more than ten feet off the ground my stomach starts feeling funny. LOL!
Here are some sounds to go with the pictures.
