About this 3D model

Hi. This is my version of DJI F450 quad copter, with legs from thingiverse, as well as gopro support. My addition was the battery holder for inside, since inside I don't have the esc, and my esc is on the bottom.(1 esc with 4 motor outpusts specially for quad copters.) I use this with the quite big battery like Zippy 4cell 14.8V 20C series 3000mAh 44.4WH code 301402
