INSTRUCTION MANUAL. HORIZONTAL STABILIZER. 1 1. Using a modeling knife, cut the covering from the horizontal stabilizer and remove it. 1 2. Draw a center line onto the horizontal stabilizer. Then slide the horizontal into the fuselage. Remove covering. Remove covering. Cut the covering away from the slot. Temporary pin to keep hinge centered. Assemble then apply drops of thin C/A to center of hinge,on both sides. See pictures below: Check to mark sure the wing and stabilizer are paralell.
ULTIMATE. 1 3. Mark the shape of the vertical on the left and right sides onto the horizontal stabilizer using a felt-tip pen Pen. 1 4. Remove the stabilizer. Using the lines you just drew as a guide, carefully remove the covering from between them using a modeling knife. When cutting through the covering to remove it, cut with only enough pressure to only cut through the covering it’s self. Cutting into the balsa structure may weaken it. This could lead to possible failure during flight.

INSTRUCTION MANUAL. MOUNTING THE TAIL WHEEL BRACKET. Snap keeper. 1 1. Set the tail wheel assembly in place on the plywood plate. The pivot point of the tail wheel wire should be even with the rudder hinge line and the tail wheel bracket should be centered on the plywood plate. INSTALLING THE THROTTLE PUSHROD. Install one adjustable metal connector through the third hole out from the center of one servo arm, enlarge the hole in the servo arm using a 2mm drill bit to accommodate the servo connector.
ULTIMATE. INSTALLING THE MAIN LANDING GEAR. 1 2. A drop of C/A glue on the wheel collar screws will help keep them from coming lose during operation. 1 3. The blind nuts are already mounted inside the fuselage. 1 1. Assemble and mounting the wheel pants as shown in the following pictures. 1 4. The holes in the landing gear should be to accept the mounting bolts. Repeat the process for the other wheel. INSTALLING THE SWITCH. 1 1. Cut out the switch hole using a modeling knife.
INSTRUCTION MANUAL. Switch. INSTALLING THE RECEIVER AND BATTERY. 1 1. Plug the servo leads and the switch lead into the receiver. You may want to plug an aileron extension into the receiver to make plugging in the aileron servo lead easier when you are installing the wing . Plug the battery pack lead into the switch. 1 2. Wrap the receiver and battery pack in the protective foam to protect them from vibration. Use a rubber band or masking tape to hold the foam in place. 1 3.

INSTRUCTION MANUAL. Lower wing. Top sid e upper wing Top side low er w ing BALANCING. 1 1) It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash. THE CENTER OF GRAVITY IS LOCATED 100-105mm BACK FROM THE LEADING EDGE OF THE WING. Lower wing. 1 2) Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 100-105 mm back from the leading edge, at the fuselage sides. 1 3.
ULTIMATE. *If possible, first attempt to balance the model by changing the position of the receiver battery and receiver. If you are unable to obtain good balance by doing so, then it will be necessary to add weight to the nose or tail to achieve the proper balance point. CONTROL THROWS. 1 1. We highly recommend setting up a plane using the control throws listed. 1 2. The control throws should be measured at the widest point of each control surface. 1 3.
