See handbook for details mm 280 400 513 Inches 11.02 15.75 20.20 The control surface seals must be in good condition to maintain the required friction to prevent flutter. Aileron friction 200-500 grams. With trim neutral there should be at least 50mm hysteresis in the elevator system. Both measured 30mm below the top of the stick. Rudder friction - up to 500 grams at TE bottom. Longitudinal datum: Wing root LE Horizontal datum: Rear fuselage bottom horizontal. For each 10 kg of pilot weight above min cockpit weight 1.5 litres of water may be put in the tail tank. For every 25 kg of water in the wings 1 litre may be put in the tail tank. Max baggage weight 5 kg (11 lb). The three 2,5 kg (5.5 lb) nose weights each reduce min cockpit weight by 5 kg (11 lb). The rear trim weight weighs 2.5 kg (5.5) lb). The fin battery max weight is 2,6 kg (5.7 lb).
