Pros: Very stable, strong, accurate, brushless (only the main motor), flies for a long time (7 to 10 minutes), the battery charges fast (40 minutes).
Cons: DX does not sell the pieces of the helicopter, as the canopy and the landing skids or even motors.
Other Thoughts: Not a toy for children, requires some ability to "get out of the ground" and keep it rovering (without breaking because some parts are fragile), I took two weeks to be able to rover.
Bottomline: If you want a toy, buy sku 14497 or 22038 or similar 3-ch heli.
