Spin...control deflection, timing...another approach?

(This has been edited for accuarcy and flow.)

If nothing else I like to ask top pilots "how" they fly various manuevers. Some chose to give little information, some share everything.

Try less elevator and less rudder during the spin...say 80% of elevator used to enter spin and 80% rudder and 10% more aileron.

Remember that you are still "flying" the model...timing is everything...try releasing rudder slightly before releasing elevator then the ailerons last. These are fractions of a second.

For Futaba 14MZ or 12MZ/FG users:

Positive spin/snap:

1. Create a new condition called "Postive Snap/Spin"
2. The condition is activated/"on" @ 90% of "up" elevator stick. The stick is the switch.
3. Using the "hysteresis" feature, the condition is "off"/normal @ 20% "up elevator.
4. Using AFR, reduce the elevator and rudder to 80%...or 20% less than it was...AND increase the aileron 10+% (fiddle until you like it.)

What did you just do? Typically, the model is driven into the spin entry with nose becoming progressively higher using "up" elevator. At 90% elevator, the new elevator rate becomes 80%...dropping the nose and beginning the spin. Simultaneously, the model rotates with the rudder (which intuitively one would assume more rudder is best...it is not). When the elevator stick is returned to 20% or less, the "normal" deflection response returns for the elevator/rudder/aileron.

Negative spin/snap:

Repeat the same steps as you did for positve spin/snap but all of the AFR values will be different!

Rules of thumb...the more rudder the deeper the stall, the more aileron the quicker the roll rate.
