Blade 200 S Fly/No-Fly Wind-based Decisions

The table below details fly/no-fly decisions for the Blade 200 S.

And Just FYI... from the Blade 200 S User Guide...

  • "Keep the helicopter approximately 2 ft (600mm) above the ground."
  • "We recommend flying your aircraft outside in calm winds or inside a large gymnasium."
  • "Place the model onto a flat, level surface free of obstacles and walk back 30 feet (10 meters)"


* Text below taken from wikipedia... Fly/No-Fly decisions are of my own.
