Step 7: Quadcopter Components: Carbon Reinforcement Spars
Carbon Reinforcement Spars
This photo shows the the 8mm x 8mm square carbon fibre spars which are recessed into grooves in the lower surface of the wing. The grooves are actually 11mm deep so that 3mm is left to run the motor wiring along the spars and everything is flush. The spars run full length between the left and right boom mounts which gives the wing the required strength. Carbon Reinforcement Spars
