Editing KAVAN Twisty 1512mm - Instruction manual (section)

===RC set installation and pre-flight check===
* Referring to the instruction manual of your radio carefully hook up the on-board electronics.
* Once everything has been correctly connected, turn on your transmitter and plug in the flight pack. Check the neutral positions and throws of all control surfaces. If you need to make the control surface throws smaller, simply move the pushrod closer to the centre on the servo arm or move it far from the control surface on the control horn. And vice versa.

* 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 capabilities of his model. The aileron differential (aileron down deflection reduced to 70 % of up deflection) is only possible with a computer radio.
* Check the rotation direction of the propeller. If incorrect, swap two of the three wires between the ESC and motor or program the ESC (refer to the [[KAVAN Plus ESCs - Instruction manual | Plus ESCs - Instruction manual]]).
* Check the correct position of the centre of gravity (CG) – 72–75 mm behind the leading edge of the wing ('''Fig. 10'''). 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. Note: Once familiar with the controls of their Twisty, skilled 3D pilots may move the CG back to 75–78 mm.
* 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.
