All the parts (http://i1380.photobucket.com/albums/ah197/Himadriroy1997/IMG-20151222-WA0004_zpskj2bhnnt.jpg) (http://s1380.photobucket.com/user/Himadriroy1997/media/IMG-20151222-WA0004_zpskj2bhnnt.jpg.html) (http://i1380.photobucket.com/albums/ah197/Himadriroy1997/DSC01807_zpsao7zbz2x.jpg) (http://s1380.photobucket.com/user/Himadriroy1997/media/DSC01807_zpsao7zbz2x.jpg.html) Preferred soldering the wires directly onto the ESC pads (http://i1380.photobucket.com/albums/ah197/Himadriroy1997/DSC01812_zpsu7vbvbx4.jpg) (http://s1380.photobucket.com/user/Himadriroy1997/media/DSC01812_zpsu7vbvbx4.jpg.html) Made a DIY PDB using a double sided copper board. For supplying the Naze32 with 5V I had bought a 5V buck converter. But it had some issues on 4S. When the output was connected to a load the voltage dropped to 2V. But no issues on 3S. So I used a LM7805 for the 5V supply. I preferred to keep the ESC inside the quad's body rather than on the arms (http://i1380.photobucket.com/albums/ah197/Himadriroy1997/DSC01814_zpsosxa5ti1.jpg) (http://s1380.photobucket.com/user/Himadriroy1997/media/DSC01814_zpsosxa5ti1.jpg.html) (http://i1380.photobucket.com/albums/ah197/Himadriroy1997/DSC01816_zpsipr84y9p.jpg) (http://s1380.photobucket.com/user/Himadriroy1997/media/DSC01816_zpsipr84y9p.jpg.html) With the Naze32 (http://i1380.photobucket.com/albums/ah197/Himadriroy1997/DSC01817_zpsmfchae9d.jpg) (http://s1380.photobucket.com/user/Himadriroy1997/media/DSC01817_zpsmfchae9d.jpg.html) Completed Quad! (http://i1380.photobucket.com/albums/ah197/Himadriroy1997/DSC01818_zpslucigag7.jpg) (http://s1380.photobucket.com/user/Himadriroy1997/media/DSC01818_zpslucigag7.jpg.html) My current PID settings are Roll P-4 I-0.035 D-30 Pitch P-4.4 I-0.036 D-35 Yaw P-10 I-0.063 D-2 I am using Betaflight 2.1.5 with BLHeli 14.3 on the Little Bees.
