Although they can be flown left or right in any aeroplane with the proper technique, a hammerhead is best flown to the left with a clockwise rotating prop, and to the right with an anticlockwise rotating prop (as in a Yakovlev type), due to propeller torque/gyroscopic effects.

The counter to a break is often a displacement roll called a barrel roll attack. A barrel roll consists of performing a roll and a loop, completing both at the same time. The result is a helical roll around a straight flight path. The barrel roll attack uses a much tighter loop than the roll, completing a full loop while only executing 3/4 of a ...
Contra-rotating, also referred to as coaxial contra-rotating, is a technique whereby parts of a mechanism rotate in opposite directions about a common axis, usually to minimise the effect of torque. Examples include some aircraft propellers , resulting in the maximum power of a single piston or turboprop engine to drive two propellers in ...
Florine chose a co-rotating configuration because the gyroscopic stability of the rotors would not cancel. Therefore, the rotors had to be tilted slightly in opposite directions to counter torque. Using hingeless rotors and co-rotation also minimised the stress on the hull. At the time, it was one of the most stable helicopters in existence. [82]
Anti-rotation exercises refer to any exercise in which you’re resisting a rotational force, explains physical therapist Kate Bochnewetch, D.P.T., C.S.C.S., founder of the Running DPT in Buffalo ...
A coaxial-rotor aircraft is an aircraft whose rotors are mounted one above the other on concentric shafts, with the same axis of rotation, but turning in opposite directions (contra-rotating). This rotor configuration is a feature of helicopters produced by the Russian Kamov helicopter design bureau.

Seated breathing method (座技呼吸法, Suwariwaza kokyūhō) / Breathing action (呼吸動作, Kokyūdōsa) / Breathing belly method (呼吸丹田方, Kokyūtandenhō) breathing is important in the execution of all aikido techniques. Here "breathing" has an additional meaning of "match with" or "accord," as the efforts of tori must agree ...
