BetaFPV 85mm Micro Whoop Frame for 8.5x20mm Motors

BetaFPV 85mm Micro Whoop Frame for 8.5x20mm Motors

Beta85 is the largest whoop style drone for the moment. With 8.5x20 motors and 48mm props, this big drone could stand much of the FPV work in your backyard, without the influence of the breeze.


Here is the recommended parts list for 85mm wheelbase distance brushed drone.

  • Frame: Beta85 Frame
  • Motors: 8.5x20mm 16000kv motors
  • Frames: 48mm 3 blade props
  • Battery: 550mah 1S lipo HV Battery


The strut design is very different and actually creates a complete X all they way back to the battery chamber. The struts between the motor mounts and ducts are fragile and break easily. So these upgraded frames stiffen the struts considerably. The struts themselves have a flat cross section which creates more bonding area with the duct.
