After Crashing my X 4inch Tube and destroying the Vista, Camera and FC, i needed a 4inch replacement that hides the electronics inside the frame. Found this fame on Aliexpress for less than 7€ and just bought 2 for the fun. Well, They are not the lightest, but so far survived all my crashes in the really harsh environment.
