The "Low rate" recommended control surface throws are suitable for a less skilled pilot and regular soaring. The "High rate" setting allows an experienced pilot to explore the full aerobatic capabilities of his model. The aileron differential (aileron down deflection reduced to 50 % of up deflection) is only possible with a computer radio.
Check the direction of rotation of the propeller. If it was incorrect, simply swap any two of the three wires between the ESC and motor or program the ESC (refer to the ESC manual).
Check the correct position of the centre of gravity (CG) – 75–85 mm behind the leading edge of the wing (Fig. 7). Adjust the CG position by moving the flight pack – if you cannot reach the recommended position, do not hesitate to add an appropriate amount of lead to the nose or tail. An extra couple of grams won’t spoil the flying characteristics - but the incorrect CG position is a killer.
Fully charge your flight pack and transmitter batteries, check the proper function of your radio and perform the range check of your radio according to its instruction manual. The range has to be almost the same with the motor off and at full throttle (no more than a 10 % decrease is acceptable). DO NOT try to fly unless the range check is 100% successful.
