I don't believe a 1/4 scale pilot will fit. The full scale RV-8 has a 24 foot wingspan and is 21 feet long. The Hanger 9 RV-8 model has 60” wingspan/52” length model dimensions. This equals 20.8% approximate scale. I believe the photo above shows the 1/5 scale pilot to be close to the correct size. Go ahead and put two in the cockpit; I wish now that I had the foresight to do so.

Base on my calculations:

20% scale = 57.6” wingspan/50.4” length model dimensions.

25% scale = 72” wingspan/63” length model dimensions.
