The Model We have chosen the scale of 1:5 rendering a model size that i easy to fly but also relatively easy to transport. Both the upper and the lower wing panels can be removed for transportation which gives very limited requirement for transportation size. With a .1.20 4-stroke engine the airplane is capable of most of the manoeuvers in the book but still as docile as you can demand from a n advanced trainer. The finished model is painted in 1939 livery and further detailing can be made as per documentation.

Lead.edge upper wing 15cm / 6” Covering and finish The model is covered and painted from the factory. Where the original had aluminum covering panels, the model has the same. This also means excellent acces to the various compartments in the fuselage when installing or servicing the radio equipment. When you have made changes in the fire wall and adapted the dummy engine to fit in front of the engine, you will have to cover the open areas with fuel proof paint. Installation of engine. Our prototype was tried with an OS 1.20 FS surcharge 4-stroke which gave more than ample thrust. The engine mounts have been installed for this size of engine and in an upright position for several reasons. The need for adequate cooling. The access to the glow plug easily and finally to get the carburator in line with the center of the tank. 1. Drill the holed for the engine in the ½" plywood ingine mount. Install blind nuts underside of the plywood aligned with the holes 2. Drill the holes from the tank to the carburator, pressure tap and the filling cap. 3. Install the engine and connect the throttle servo. No side or down thrust is deemed necessary. You can use an flexible exhaust manifold to lead the exhaust out under the center bottom panel to give a better apperance. Installation of servos, tank, battery and receiver. The aileron servo is installed in the cockpit flooring. The elevator servo and the rudder servo are also installed in the cockpit flooring. The trottle servo is installed behind the engine as well as the tank, booth on the engineboard. Battery pack and receiver are positioned in the upper part of the tray. The switch can be mounted on the front cockpit instrument panel. 1. Attach a ball link head to joystick and rudder bar in the appropriate holes. You may have to enlarge the holes to take the screw from the ball link (Dubro #189 set of 2). 2. Install the servos for rudder and elevator and temporarily connect the servo arms to the ball links. Deflection for elevator is 20° up and down and for rudder 30° right and left.. 3. Install and connect the throttle servo in the fashion you prefer. 4. Install the tank in the available space at the right side next to the rudder and throttle servos.. 5. Install the aileron servo in the bulkhead. The aileron connecting rods attaches to the servo arm. Deflection of the ailerons should be 20° up and down. The servo arm should be fashioned to take 2 clevices approx 1/8" apart. 6. Install the radio switch on the dash board. 7. Place the receiver in the upper part of the tray and the battery pack in front of the lower firewall, wrapped in foam rubber and secured with rubber bands. Assembly of the PT17 All parts have been assembled at the factory and only disassembled for transportation. Rudder wires and elevator pushrod are factory adjusted but may need some tensioning adjustment after a while. Aileron bellcranks are permanently adjusted to the connecting rod. Assembly of the tail unit See detail drawing. 1. Attach horizontal tail(3) to fuselage using 3 pcs 4 mm nylon countersunk screws. Make sure that stabilizer is flat against fuselage. 2. connect the elevator control rod to the elevator horn. 3. Insert vertical fin and secure to tailpost bracket and front of stabilizer. Attach rudder on to the fin with hinge pins. 4. Secure the assembly with screws to the stabilizer and to the tailpost. Attach the top stabilizer fairing and secure with screws. 5. Attach fin and stabilixer support wires to top of fin using 2 mm screw and nut (from top side of Stearman Kaydet PT17 ARF 7
