More prop testing on the Floating Kidney design for FTFC20. This plane is very nice, like the Cadillac of Nutballs, and it glides/dead-sticks like a boss, and with the right prop, has some really solid high alpha. It's easy to fly, maneuverable,loops easy.Anyone not already in this challenge should seriously consider joining in the fun!There are so many designs to choose from and it doesn't have to be complicated to turn out awesome. This was designed as a chuck glider in 1947! Planes like the Nutball have been popular in aeromodelling longer than most people think.
