Setup

• For the first 5 flights, only run the battery down to 50%, 1.5 minute flighttime, it will help lengthen the life of the LiPo
• If it swings or wobbles when in hover, try to fasten one or both blades (upper/lower)
• Let the motors cool off after a flight, 5-10 minutes
• Check the tail rotor for plastic residue left from the manufacturing
• To enter forward flight mode, remove the tail fin, boom support, and skids, I think this is how it should fly by default! Weight: 15.1 grams
  • Optionally, bend the skid support screw-tabs down to raise the body above the on/off-switch sticking out

• Mount small E-flite battery between the skids
  • Replace battery with higher capacity E-flite battery [1]
