Section 14: Receiver, Battery and Scale Accessories Step 14All decals will be factory installed. Step 15Use RC-56 canopy glue to attach the radiators to the wing. Step 16Repeat Steps 13 though 15 to install the remainingaccessories, as there is a right and left to theseaccessories.Recommended Center of Gravity (CG)An important part of preparing the aircraft for flight isproperly balancing the model. This is especially importantwhen various engines are mounted.Caution: Do not inadvertently skip this step!The recommended Center of Gravity (CG) location for theB-25 Mitchell is 3 3 / 4-in (95.25mm) behind the leadingedge of the wing against the fuselage. Mark the locationof the CG on the bottom of the wing as shown. Turn theairframe upright to balance. If necessary, move the batterypack or add weight to either the nose or the tail until thecorrect balance is achieved. Stick-on weights are availableat your local hobby store and work well for this purpose.72
Control ThrowsThe amount of control throw should be adjusted as closelyas possible using mechanical means, rather than makinglarge changes electronically at the radio. By movingthe position of the clevis at the control horn toward theoutermost hole, you will decrease the amount of controlthrow of the control surface. Moving it toward the controlsurface will increase the amount of throw. Moving thepushrod wire at the servo arm will have the oppositeeffect: Moving it closer to center will decrease throw,and away from center will increase throw. Work with acombination of the two to achieve the closest or exactcontrol throws listed.Elevator Low Rate7 degrees, 3/8-inch or 8.5mm up/downElevator High Rate13 degrees, 5/8-inch or 16mm up/downNote: Elevator throw is measuredat inboard end of elevator.Aileron Low Rate10 degrees, 3/8-inch or 9.5mm up/downAileron High Rate15 degrees, 9/16-inch or 14mm up/downNote: Aileron throw is measuredat inboard end of aileron.Half Flap Position20 degrees,1-inch or 26mm downFull Flap Position40 degrees, 1 15 / 16-inch or 49mm downNote: Flap throw is measured atend of flap against the fuselage.Once the control throws have been set, slide the clevisretainers over the clevis to prevent them from openingduring flight.Rudder Low Rate10 degrees, 1/2-inch or 13mm right/leftRudder High Rate16 degrees, 13/16-inch or 21mm right/leftNote: Rudder throw is measured atthe widest part of the rudder.Range Test Your RadioRange check your radio system before each flyingsession. This is accomplished by turning on yourtransmitter with the antenna collapsed. Turn on the radioin your airplane. With your airplane on the ground, youshould be able to walk 30 paces away from your airplaneand still have complete control of all functions. If not,don’t attempt to fly! Have your radio equipment checkedout by the manufacturer.73
