There's a 5" FPV frame for sale.
This is an original frame kit from FlyFishRC.
I bought that in France, just changed my mind about the build, I need another frame size.
The box has not been opened, everything is brand new.

Volador VD5 is the Deadcat style frame that lets you get props out of the view. 20x20mm and 30.5x30.5mm stack mounting holes, 20x20mm, 25x25mm VTX mounting makes this frame super convenient! The unique easy-swap arm design and tight-fitting structure design reduce the resonance to the minimum. The high-quality TPU parts adds up to the comfort of use and make the build look very neat and snug.
