Overview:
This “Lite” version of the Student Flyer airframe is made from 3mm Depron instead of 6mm Depron. Reduced airframe weight allows for the use of a 7mm geardrive instead of the 8mm geardrive used in the standard version. Also, this 3mm Depron version allows for the use of a smaller 130 to 150mah battery. These weight savings bring the all up flying weight to just 44 grams compared to 69 grams for the standard version. With the same wing area this “Lite” version is a real floater suitable for indoor flying venues and also outdoor flying when there is no wind.

Kit Features

Recessed Tractor Prop
The airframe has been designed to have a recessed tractor prop protected by the fuselage skid. This gives protection to the geardrive and prop in the case of flying into a wall. Less chance of damage means less downtime and less repairs. Recessing the prop instead of simply making a pusher prop design allows us to keep all the good flight characteristics of a tractor prop setup. The boom which protrudes in front of the prop also gives the perfect location to mount a micro FPV camera.

FPV Options
The fuselage skid has a 20mm flat section on the top which can be used to mount a micro FPV setup or camera. In this setup, the standard battery bay is used for the FPV battery and the RC gear battery is mounted further back on the fuselage to achieve the correct balance. The flying weight increases to 54 grams.

Control Surface Protection
At schools, the airframes will usually be put into cupboards for storage after use, so this protector on the back of the fuselage protects the control surfaces from accidental bumps.

Servo Mounts
The airframe includes these wooden servo mounts specifically designed for linear servos which match with the recommended receiver. Servos are held in with four screws instead of being glued to the airframe. Having an RC system where servos can easily be removed and swapped out if they happen to fail, reduces downtime and makes for fast and easy repairs.

Wing Design
The wing construction is quite basic and easy to complete in minimal time. The wings consist of just one sheet of foam which is bent at two points to form the air foil. After bending, carbon rods are placed in the gaps for strengthening.

Wing Positioning
The wings are also designed to be removable, being attached with rubber bands. This allows for the airframes to be easily stacked away in the cupboard between classes.
The main wing spar also has a wooden tongue which locates into a slot in the airframe to hold the wings in exactly the right position. At the back of the wings, another positioning lug slots into the trailing edge of the wing to keep it dead straight.
