The firewall, prepared for the recommended Leomotion drive

This frame is glued in place by the customer with epoxy glue. If required, a different type of motor can be used.

For optimal performance, we recommend the use of our LEO 4120 710 KV Outrunner.

The recommended propeller for the LEO 4120 710 KV is a standard APC 11 x 8″ glow prop – not the EP prop.

Installation of the rudder servo. We recommend either a Savox SH-0252MG or a Futaba 3003

The same servo is used for the nose landing gear steering and the rudder. The nose wheel steering uses 2 flexible trace wires. The rudder pushrod is a single 1.2mm steel rod.  The steel wire to the rudder is fed through a pre-installed Bowden cable tube. The customer will need to complete the installation by crimping and soldering the wires to clevises at the rudder and nose wheel.

On the rudder a  horn is mounted and connection is completed by soldering the steel wire to the clevis and then feed to the rudder servo down the preinstalled Bowden cable.

The fiberglass fuselage is designed for the installation of our electric retracts CP A-2. Install the nose landing gear, mark the mounting holes and pre-drill 4 screw fastening holes with a 1.5 mm drill bit.

Installation of the retract nose gear (Retract set CP Design A-2)

The receiver is simply attached to the fuselage sidewall with Velcro tape

The wing fixing screw mount is installed from the top side and uses a single captive ‘T’ nut

Clean the fuselage then fix the supplied decals

There is enough space for up to 6S batteries in the battery box

We recommend a 6s 5000mAh LiPo at 675g. This will ensure that the Center of Gravity is in the correct location

At the top of the fuselage shown by the red circle, you need to drill a small hole – 1mm diameter. This will need additional wood reinforcement. Fit a self-tapping screw in and under the fiberglass fuselage area, glue a small piece of hardwood to the fiberglass to make this area a little stronger. Leave a gap of about 1mm between the screw head and the fiberglass fuselage. The screw acts as a locating peg and a guide for the fiberglass canopy.

Cut a small slot in the canopy as shown on the picture. This locates the canopy at the rear. The canopy will be inserted between the screw and the fiberglass fuselage.

Repeat for the fuselage side wall. Glue 6 wooden reinforcement straps to the inner side of the fuselage side walls using epoxy adhesive.

Locate the canopy over the fuselage and mark and cut 6 slots to locate inside the screw heads

Here you can see the 6 straps which are glued to the fuselage side wall and fitted with a self-tapping screw. Again, when inserting the screws, leave 1 mm between the screw head and the fuselage side.

This shows the canopy correctly fitted. Note that the screws should be tight enough to allow the canopy to slide into place but without it being able to rattle. The fit should be snug but not tight.

The canopy is pushed in between the screw heads and the fuselage side. It is not necessary to tighten the screws further.

Finally, to secure the canopy to the fuselage, it is held in place at the front by one metal screw and this is tightened. This is the only fixing screw required to retain the canopy.

The next phase of construction is the fitment of the tailplane. The 2 tailplane halves are joined with 2 carbon fiber tubes pushed through the fuselage. 2 Servo extension cables are inserted from the front to the rear of the fuselage and exit through the round holes at the tailplane root

Drill a small hole in the carbon fiber tube here. This hole becomes the guide for the horizontal stabilizer mounting bolt.

Glue the front carbon tube into one tailplane half only, it is not glued into the other half.

Drill a small hole in the carbon fiber tube here. This hole becomes the guide for the horizontal stabilizer mounting bolt.

This screw secures the completed tailplane.

A Savox SH-0255MG servo is installed in each of the two horizontal tailplane halves. The two linkages from the elevator servo to the elevator consist of supplied M2 threaded rods and 2 clevises.

The supplied rudder horns are screwed to the tailplane elevators, aligned  to match the servo cutout and connected to the servos with the supplied linkages.

The tailplane and fin are protected by Maho wing-bags.

The two wing halves are joined in the middle by the enclosed tubes and glued together with epoxy glue.

At the rear, one screw in the middle is quite sufficient, in the middle of the fuselage on the wing mounting plate a blind ‘T’ nut is attached.

Next to the wing mounting plate on the fuselage side wall, the receiver is attached with a Velcro strap.

The mounting hole with sunken drive nut.

The 2 main landing gear mechanisms are installed in the prefabricated space. The servo cables are pushed through the wing towards the root down the precut servo cable tubes. Note that servo extension cables are not included in the accessories pack.

The supplied 55mm wheels fit the wheel wells perfectly.

When the two wing halves have been glued together, the fiberglass underwing part is glued flush to the fuselage on each wing half.

The aileron servos are mounted in the two cutouts in the wing. Servo extension cables are laid through the surface to the center of the wing. We recommend servos: Savöx SH-0252MG or Futaba 3003. Note that servo extension cables are not contained in the accessories package

The horns are screwed on the ailerons and aligned to the aileron servo shaft. The servos are now connected to the rudder horns by means of the supplied linkage. The two aileron linkages to the servos consist of M2 threaded rods and 2 clevises for each pushrod.

In the wing root, the 4 extension cables (2 servo and 2 undercarriage cables) are threaded out.

Here is the finished wing. The surface is cleaned and the enclosed decal sheet applied.
