The Mini QBiT has seen a ton of design iterations. From the wings, to the frame, to the nose cone- the final product is a culmination of dozens of structural and aerodynamic improvements designed to maximize performance.

Structure:
  • The carbon fiber infused polycarbonate used for the frame yields a high strength to weight ratio.

  • The frame's structure is optimized to take advantage of the stiffness of the wings.

  • The frame's shape is designed to allow for extreme durability in crashes.

Aerodynamics:

The frame:

  • The frame's arms have a small profile in forward flight to minimize drag. The nose cone reduces the blunt body drag that would otherwise be present with the flight controller electronics alone.

The wings:

  • The thin cambered airfoils are optimal for the low reynold's number that the Mini QBiT operates in. The winglets reduce the induced drag and also act as landing gear while providing directional stability in forward flight.

Propulsion:

Battery:

  • The battery choice was chosen based on the energy to weight ratio. The 3s 850 mAh battery is optimal for this size vehicle, as it is a good tradeoff between battery weight and total energy.

Motors:

  • The 3800KV motors and their respective operating RPM is optimal for the hover and high speed flight that the vehicle is capable of.

Overall, the vehicle has a thrust to weight ratio of 6:1. This allows for high speed flight and a wide range of payload weights.
