A maneuver in which the helicopter is transferred from upright to inverted, or inverted to upright, typically while not moving appreciably up or down or over the ground (a 'stationary flip'). It can be performed as a half flip, a full flip (for example upright through inverted and back to upright) or as continuous flips.

Flips can either be done as tiny loops ('elevator flip') or like tiny rolls ('aileron flip'). Elevator flips can be divided into the flip beginning with the nose of the aircraft coming up, (a 'backflip'); or the nose dropping at the start, (a 'front flip').


  • Before performing a flip, it is useful to give a boost of collective to get the model moving upwards. Start the flip with 0 degrees collective and catch the model with negative collective as it becomes fully inverted.
  • If doing a complete flip, it is helpful to use a short burst collective to maintain height as the helicopter becomes inverted.
  • If doing a complete (360 degree) flip with low flip rates, the main rotor will act as a wing as the helicopter is falling (even at zero degrees pitch), causing the helicopter to slew sideways (in an aileron flip). This can be mitigated by keeping collective applied at the entry to the flip, and extending the burst of collective when the model is inverted, particularly as it starts rolling from inverted to upright.
