The Skidmark Nano is a pocket size drone racer. Diagonal motor spacing is only 140mm. It suits the 1105 size motors and 3 inch HQ props. It has tilted motor mounts for instant speed and low drag and is very competitive for car park racing. Because it is so small its easy to get through the airgates and can stand up to lots of punishment. We recommend a smaller size Naze board like the PIKO BLX Micro or Flip32 mini flight controller. You will need 4 aluminium spacers 20mm long. We recommend the Elgae FOV127 FPV combo from RCTimer.
