Other items needed are,
Double sided foam mounting tape, PVC container to protect the APM2 flight controller. 200W soldering iron and flux core soldering lead. Hands free soldering stand, this is a MUST have for soldering wires and connectors . Cutters, pliers, hex and ordinary screwdrivers. Screws and nuts to secure the landing gear, default screws are too small from the frame kit I bought, so I used my own 3mm bolts and lock nuts. Nylon cable ties to tie the wider landing gear to the narrower landing gear of the hexa frame. Velcro straps to hold the battery. Fiber tape for sticking the Power distribution cables to the frame. Glue gun to insulate the power distribution cable
I built my own Power distribution using 2 loops of 12AWG black and red cables, soldered the ends together and made six cuts along the cable and carefully solder a female Polymax 3.5mm connector onto it. A separate cable is soldered with a XT60 connector for the battery. ESCs power cables are too short and are extended with the 12AWG cables and soldered with the male Polymax connectors in turn are connected to the self soldered Power distribution cables.
