CAUTION
: You must adjust your aircraft’s center of
gravity and balance your model properly before attempting fl ights.
CENTER OF GRAVITY
An important part of preparing the aircraft for fl ight is properly balancing the model. The Center of Gravity range
supplied here is a guideline based on testing. Deviation from the measurements we provide is possible and may result
in a model that suits your fl ying style better. Start with the recommended Center of Gravity, then feel free to experiment
with different balance points. We advise adjusting progressively and cautiously.
1.
Attach the wing panels to the fuselage. Make sure to connect the leads from the aileron and retracts to the
appropriate leads from the receiver. Make sure the leads are not exposed outside the fuselage before tightening
the wing bolts. Your model should be fl ight-ready before balancing. The retracts (if installed) must be in the UP
position when chencking the CG of the F6F-5 Hellcat.
2.
The recommended Center of Gravity (CG) location for your model is 5 inches (127mm) behind the leading edge of
the wing.
3.
When balancing your model, make sure it is assembled and ready for fl ight. Support the plane inverted at the
marks made on the wing with your fi ngers or a commercially available balancing stand.
It may be necessary to add weight to the nose of your model to achieve the correct
Center of Gravity, or to adjust the flight handling to suit your flying style.
All of the product development aircraft were completed and flown without any additional weight being added..
CONTROL THROWS
1.
Turn on the transmitter and receiver of your model. Check the movement of the rudder using the transmitter.
When the stick is moved to the right, the rudder should also move right. Reverse the direction of the servo at the
transmitter if necessary.
2.
Check the movement of the elevator with the radio system. Moving the elevator stick toward the bottom of the
transmitter will make the airplane elevator move up.
3.
Check the movement of the ailerons with the radio system. Moving the aileron stick to the right will make the
right aileron move up and the left aileron move down.
4.
Use a throw meter to adjust the throw of the elevator, ailerons and rudder. Set the high rates fi rst, then use the
rate functions to set the remaining rates.
Aileron: (15 –20% Exponential)
High Rate
Low Rate
Up:
15/16 inches (24mm)
23/32 inches (18mm)
Down:
25/32 inches (20mm)
19/32 inches (15mm)
Elevator: (20% Exponential)
High Rate
Low Rate
Up:
19/32 inches (15mm)
13/32 inches (10mm)
Down:
19/32 inches (15mm)
13/32 inches (10mm)
Rudder: (10 –15% Exponential)
High Rate
Low Rate
Right:
19/32 inches (15mm)
13/32 inches (10mm)
Left:
19/32 inches (15mm)
13/32 inches (10mm)
These are general guidelines measured from our own fl ight tests. You can experiment with different rates to match
your preferred style of fl ying.
Travel Adjust and Sub-Trims are not listed and should be adjusted according to each individual model and preference.
Always install the control horns 90 degrees to the servo center line. Use sub-trim as a last resort to center the servos.
We highly recommend re-binding the radio system once all of the control throws are set. This will keep the servos from
moving to their endpoints until the transmitter and receiver connect.
