F4U's torque
« Reply #30 on: September 21, 2005, 04:38:52 PM »
The F4U behaves like any tailwheel airplane.  You should not use brakes on landing.  Wheel landings and 3 points are both fine.  Simply use your rudder to align the longitudinal axis with the runway, and make SMALL adjustments.

The CG of all tailwheel airplanes is BEHIND the main gear.  Therefore, if the tail starts to move left or right, it has a tendency to move MORE in the same direction ---> negative stability.  That is why you can't allow much deviation in tail movement, using the rudder.  

Just like in the real world, if the tail does start to "get away", you apply full power and do a go-around.  That is the safest thing to do.

As the tail comes down after landing, GYROSCOPIC PRECESSION, (Not spiraling slipstream, torque, or P-factor) will cause the nose to gently yaw to the RIGHT.  (During a wheel landing, not a 3-point).  Add a small amount of left rudder as the tailwheel comes down.  Add too much, you'll loop her, too little, you'll loop her.  As tail comes down, stick to your belly and apply brakes.

The training video for the F4U says to do 2 point landing and to keep the tail up as long as possible because at the 3 point angle there isnt enough clean air to allow the rudder operate effectively.

Since watching that video I dont have as many problems with ground looping when I do 2 point landings.

If you have your Left and Right brakes bound to C and V, you can easily control any spin as it goes down the run way AND slow down the aircraft at the same time.
