I have a CC Panther light and it flies like a dream.
I have build it very light - No speed brakes, No moving Gear doors and only one fueltank 2,8L (Standard is 3 tanks = 5,4L)
I have used Electron Retracts and legs. It is powered by a JetCat P100.
Flying weight 14kg with fuel.
You need to build as light as possible othervise you will end up with a flying weight of 17-18 kg. my needed 600g lead in the nose
