Thanks Combat,
The wingspan on this Giles is 49.5 and the wing loading is to the higher side. When test flying the model I almost lost it twice due to this snap at low altitude. I did not know that would occur. I have learned to not get into a situation that calls for full elevator.

"The Wall
What it is: The Wall is a Parachute turned on end. The model starts in normal level flight and suddenly corners nose up 90º...as if it hit a wall.
Setup: A 3D setup is a must, i.e. 40° elevator, and be sure to use Expo. Flip the switch to turn on the spoilerons. This will help to keep the Extra from teetering back and forth. Setting the CG toward the aft location will help, but I have had great results even at the forward CG location.
How to do it: Start from about 100 feet straight and level,
chop throttle, and as the model begins to slow down, quickly pull full up elevator. When the plane corners to vertical, add full power and release the up elevator. (Tip: Start a low speed and add power at the same time that you begin to pull full up elevator).
Recovery: Simply release the elevator, go to full throttle, and fly out upward.
Advanced Recovery: Juggle the throttle to sustain a hover and transition into a Torque Roll.
Worst way to mess up: If you don't get the throttle in quickly enough, the model falls backward. Not good."
