RECOMMENDED CONTROL SURFACE TRAVEL:
Ailerons - Low Rate: 1” Up and Down
Ailerons – High Rate: 2” Up and Down
Elevator – Low Rate: 1” Up and Down
Elevator High Rate: 2” Up and Down
Rudder – Low Rate: 1-1/2” Left and Right
Rudder – High Rate: 2-1/2” Left and Right
3D CONTROL SURFACE TRAVEL:
MAXIMUM TRAVEL ON ALL SURFACES!
A Note About High Rate Throws:
High rate and 3D control throws are only meant for extreme aerobatics
- not for normal flying. You should be competent and comfortable
flying your EDGEtra with normal control throws before attempting high
rates.
A Note About Exponential:
You will find lots of opinions about the proper amount of exponential
travel to use on each control surface in both low and high rate settings.
The best aerobatic pilots in the world agree that you will want more
expo at high rates than at low rates. After test flying, adjust your
settings as needed to obtain the control feel you want. Consult your
radio manual to find out how to adjust the exponential settings of your
transmitter.
FLYING
When it comes to test flying a new model, we always advise modelers
to choose a calm day with little or no wind. These conditions allow you
to better evaluate and more accurately adjust the trim requirements
for your airplane. As we’ve mentioned before, a good running, reliable
motor is a must for the ultimate success of your airplane. Take the time
to solve any power system problems before you try to fly.
Always make it part of your pre-flight routine to check each control on
the airplane, making sure the surfaces are moving in the correct
directions. Also check each control linkage to be sure they are secure
and that nothing is loose. With all the controls checked, make a range
check with your radio system, making sure everything is working
perfectly.
Taxi the EDGEtra out to the take-off position on the flying field, (holding
up elevator during the taxi will keep the tailwheel firmly to the ground).
For takeoff, the airplane should be lined-up with the center of the field
with the nose pointed directly into the wind. Hold a little up elevator
and smoothly advance the throttle - do not slam the throttle full open
all at once. As the EDGEtra begins moving forward, back off of the up
elevator input and use the rudder, only as needed, to correct any
engine torque and/or wind induced deviations from a straight take-off
run. Allow the airplane to lift off, using ailerons to keep the wings level.
Climb to a reasonable altitude before making any trim changes.
With the control movements set at the “low rate” measurements
provided in this manual, the airplane should exhibit smooth,
predictable control. Try a few loops and rolls. You will find that the roll
rate is not especially high at the initial aileron settings but they can be
very axial with practice. Inverted flight is easy, requiring surprisingly
little down elevator for level flight. The EDGEtra also performs nice
inside and outside loops, snap rolls, Immelmann turns, stall turns,
Cuban eights, and spins. As with any aircraft, getting consistently good
results is a matter of practice.
While still at altitude, throttle the engine back to idle. This will give you
a good idea of the glide characteristics. While still at idle, steadily
increase up elevator input to get a feel for the stall characteristics.
With practice and a little rudder input, the EDGEtra will become your
favorite 3D plane on the market! Stalls tend to be very gentle with one
wingtip or the other dropping, followed almost immediately with
resumed flight as soon as the elevator is neutralized. This is great
information to have when setting up your first landings.
With the control movements set at the “high rate” measurements
provided in this manual, the airplane will be able to perform any 3D
maneuver you can think of!
Landing the EDGEtra is easy, due to the light wing loading and 3D
nature. We suggest using a standard landing approach, beginning with
a throttled back downwind leg and base turn to the final approach into
the wind. During final approach, keep just a little power on until the
airplane is exactly where you want it for touchdown. In crosswind
situations, a little rudder input will likely be needed to keep the
airplane lined up with the runway. The EDGEtra can be easily landed
on either main wheels or in the three-point position. After landing,
always remember to hold up elevator when taxiing to keep the
tailwheel firmly to the ground.
We sincerely hope that your EDGEtra will provide you with many
enjoyable flights. Please operate your airplane in a safe, responsible
manner with respect to other flyers, spectators, and property.
Good luck and safe flying!
