GREAT PLANES Gee Bee Instruction Manual page 34

while on the downwind leg. Allow the nose of the model to
pitch downward to gradually bleed off altitude. Continue to
lose altitude, but maintain airspeed by keeping the nose
down as you turn onto the crosswind leg. Make your final turn
toward the runway (into the wind, just like you did for your
takeoff) keeping the nose down to maintain airspeed and
control. Level the attitude when the model reaches the
runway threshold, modulating the throttle as necessary to
maintain your glide path and airspeed. If you are going to
overshoot, smoothly advance the throttle (always ready on
the right rudder to counteract torque) and climb out to make
another attempt. When you're ready to make your landing,
flare when the model is a foot or so off the deck; smoothly
increase up elevator until it gently touches down. Once the
model is on the runway and has lost flying speed, hold up
elevator to place the tail on the ground, regaining tailwheel
control. You can also land the Gee Bee on the main wheels
and execute a slightly longer roll out with the tail off of the
ground. From our experience we have found it takes a bit
more practice to achieve a nicely flared, three-point landing
than it does to land the Gee Bee on its wheels.

One final note about flying your model. Have a goal or flight
plan in mind for every flight. This can be learning a new
maneuver(s), improving a maneuver(s) you already know, or
learning how the model behaves in certain conditions (such
as on high or low rates). This is not necessarily to improve
your skills ( though it is never a bad idea! ), but more
importantly so you do not surprise yourself by impulsively
attempting a maneuver and suddenly finding that you've run
out of time, altitude or airspeed. Every maneuver should be
deliberate, not impulsive. For example, if you're going to do a
loop, check your altitude, mind the wind direction (anticipating
rudder corrections that will be required to maintain heading),
remember to throttle back at the top and make certain you are
on the desired rates (high/low rates). A flight plan greatly
reduces the chances of crashing your model just because of
poor planning and impulsive moves. Remember to think.
But always stay in control and fly in a safe manner.
GOOD LUCK AND GREAT FLYING!
