Aileron Modification Instructions

Ailerons can be added to the Student flyer during the build process or afterwards. There are two options for mounting servos as described below. Please note that adding ailerons will not make this plane aerobatic – it’s still a trainer plane. Some pilots may prefer to fly using ailerons or prefer not having both rudder and elevator on the one stick. Please also consider that a similar effect can be achieved by simply plugging the rudder servo into the aileron port on the receiver or setting up mixing on your transmitter.

Single Servo Above Wing Mount. Dual Servos Under Wing Mount. Advantages: Advantages: Only one servo needed so less weight. Better aileron surface control Quick and easy to implement. Looks better than single servo mounted on top

Disadvantages: Disadvantages: Rubber bands need to be threaded under pushrods. JST SH Y Connecter is needed to split the servos. Servo position requires control horns to be placed 2 Servos needed so extra weight and expense. an angle on the control surfaces. More time required to implement.

Cut the ailerons according to the dimensions shown below.

220mm

45mm

18mm

If modifying a pre-built airframe, remove these rib parts from the aileron surface.

If adding ailerons before you build the wings, measure ad pre-cut these parts off 4 of the 6 wing ribs.

Cut an angle into the aileron control surface to allow it to hinge.

Do the same for the wing and also cut back the wing ribs.

Trim 2mm off the end of each control surface to give clearance for when it moves.

Use masking tape as shown to hold the control surfaces in place if the wing has been pre-built and use blenderm hinge tape to attach the control surfaces.

Procedure for Single Servo Above Wing Mount

Use a ruler and lay it from the hole in the aileron horn to where the control horn will be placed and rule a line on the control surface to indicate where to cut the slot for mounting the control horn.

Glue the control horns in place and attach your control linkages.

The servo will protrude under the wing surface so you will need to cut a slot in the airframe here to accept the bottom of the servo when the wings are attached.

Cut out a gap in the airframe here to allow the servo lead to exit the airframe, and plug it into the aileron port on your receiver.

Procedure for Dual Servos Under Wing Mount.

Cut a servo mounting hole in the middle rib of each wing. You may optionally wish to use servo mounting plates so you can screw the servo in, instead of gluing it in.

Secure the servo in place and cut a small hole in the rib closest to the fuselage to feed the plug through.

Connect your Y Connector to the servo leads.

JST SH Y-Connector Product link Note: the wire order on this connector is different but the colour of the wires is not important when using this connector in this scenario.

Use Blenderm Hinge tape to tape down the servo lead.

Mount your hinge in line with the servo arm and connect up your control linkages as shown here.

Cut out a gap in the airframe here to allow the Y-Connector lead to exit the airframe, and plug it into the aileron port on your receiver.

Mixing Note: You may wish to set some aileron  Rudder mixing on your transmitter.
