The two main solutions presented for the frame were a quadcopter and hexacopter. A hexacopter would give us the ability to lift greater amounts, and more reliability as the drone would still be able to safely land if one motor or propeller broke. One advantage of a quadcopter is that it can have larger propellers and is cheaper as it only needs four motors/controllers. We ended up going with a quadcopter for the above advantages and in order to provide enough lift focused on finding motors that were suitably efficient

motor and prop selection - TheIn previous competitions, WARG has used 14V motors as the drone has not been required to carry a heavy payload. This year however, since the payload could be up to 2kg, the decision was made to switch to larger motors. A custom excel sheet was used to calculate the lift and flight time for different combinations of motors, propellers and batteries. Using this data, the final decision was to go with T-Motor Antigravity 5008 motors and 18” propellers.
having 2 layers for batteries and other electrical components? removing arms so easily replaceable?
