[NSRCA-discussion] Flight conditions?

[Adam Glatt]

Yeah, spin condition has more expo.  I switch conditions shortly after 
cutting throttle.  The plane is still moving fairly fast, so I'm just 
holding in normal elevator to maintain inverted flight.  So, I am 
flicking it on the level flight leading up to the spin, but with our 
inverted spin entry there is elevator input present when I flick it.

Spin and snap are completely different.  Spin is almost no aileron, tons 
of elevator, and lots of rudder.  Snap is tons of aileron, moderate 
elevator (this travel is set for the break, not for during the spin - 
during the spin I hold in only about 1/5 of my elevator stick), and a 
fair bit of rudder.

In my experience, pattern planes spin best with no aileron input.  My 
Mantis required aileron to do a clean spin entry, but once the rotation 
has begun I took it completely out.  The Twister seems to require some 
aileron throughout, as a pure elevator and rudder spin puts it deeply 
stalled, making hitting the exit very difficult (continues about 1/2 a 
rotation after I return sticks to center).  It looks better with no 
aileron, but missing the exit by 45 degrees doesn't look so good.
