This is my fourth quadrocopter and third Lumenier frame (came from the QAV400 and QAV250 down to this) and this got rebuilt from my previous QAV210 posting. As with all my builds I have a great focus on aesthetics and durability. Everything is soldered on or has solid connections. Loctite whereever feasible. Liquid tape covering screws as there is danger of damaging the cables or shorts (not shown in pictures). Cables run as short as possible and each component is necessary. No OSD because a battery alarm via telemetry (Futaba system external voltage sensoring) is enough for me.

AUW: 617g

Special considerations:
– I used the thicker 4mm body plate and applied super glue around the sides to strengthen the carbon fibers and sanded afterwards
– The LiPo is secured by a rubberized strap but I also glued a rubber sheet on the top plate to prevent slippage
– The PDB is glued and screwed on the main plate as the stress is higher due to unplugging the XT60 from it
– The RC reciever got decased and the pin headers removed to make is small enough for the space available.
– I've yet to find double sided tape that behaves better than 3M VHB. Good stuff.
– I went for fancy anodized aluminium screws holding the motors and frame plates. They save about 10g in total.
– The GoPro mount is custom made from a stock GoPro Session frame and a polystyrene plate screws to the top plate.
