With a small modification, the Flite Test Mini Scout is an excellent progression model for a beginner RC pilot.
When Graupner stopped importing kits and foam board sheets for Flite Test models into Europe, I looked for an alternative.
Maker Foam boards have a very low weight (approx. 0.19 g/inch²) compared to similar boards manufactured in Europe. The most accessible substitutes are 5 mm Kapa Line boards (0.41 g/inch²) or Foam-X boards (0.38 g/inch²).
For cutting Kapa Line boards, in addition to a sharp snap-off knife and a straight edge, a CNC machine with a laser is suitable. The included SVG file has been tested with the ACMER P2 and the control software LaserGRBL. For cutting Kapa Line boards, the laser power was set to 60% and the feed rate to 500 mm/min; scoring requires only 20% power (33 W laser).
Despite the higher weight of the Kapa Line boards, the FT Mini Scout flies excellently. Adding a servo for aileron control turns it into an agile aerobat. The build process is described in the video.
Technical specifications of the modified FT Mini Scout:
- take-off weight: 350 g
- wingspan: 60 cm
- length: 50 cm
- battery: LiPo 3S 850 mAh
- receiver: FrSky ACCESS RX6R
- ESC: 20 A
- motor: Rotorama Lite 2205 2300 kV
- propeller: 6 x 4.5 (3D printed)

the most important part: the pilot (without him the aircraft wouldn't fly)
