this small project was intended to make the Diatone Blade 150 with 150 arms, to use the 4045 prop. without needing to cut it down to 3". Less weight more power more aerodynamic More FUN new Update....if you are using the VTX that i have put in the description of the project then this might come in handy. I have decided to make a hole specifically for the Get Fpv 200mW VTX ( which gets very hot and will loose image if left on for a while) and also allow you to put a aluminium radiator. A bit of processor cooling paste and a small zip tie will hold the two together without any problems. Let me know what you think :) Sincerely yours... AndreiDesigned for specific parts such as NAze32 miniAfro or cc3d Atom with no case and no pins, minim micro osd, Get Fpv 200mW 8 channel VTX or FT952 5.8Ghz VTX, Banggood 600TVL Camera.
