Summary

The redesigned 3D printed MHQ2 folding mini quadcopter frame has arrived! Building on the success of the original MHQ frame, we have improved the functionality, durability and stability of this frame. The MHQ2 uses the same arms and hardware from the MHQ with the addition of 4x more 18mm screws and 4x locknuts. The use of 6″ props is possible with the new XL arms.

KEY NEW FEATURES:


  • Redesigned base with greatly reduced torsion for better flight stability.
  • Camera and battery have a lower center of gravity. Both now mount down on the flight control deck.
  • Hardtail mounting: you can skip the clean layer and mount the top plate directly to the base.
  • Wider landing gear and slots on the underside of the baseplate for mounting the battery if preferred.
  • Improved landing gear thickness and durability.
  • Mounting holes for SMA extension cables.
  • Integrated GoPro and Mobius mount. Reinforced structure reduces damage in a crash and elevates the GoPro for the use of a USB live-out FPV cable.
  • Support for M3 “bobbin” style vibration dampeners.
  • Now with 35mm spacers to support flight controllers with straight header pins.
