Here you can see exact dimensions for each side connection. Notice there are two ways to control
TV, with same servo as you use for rudder ore with separate servo. Ussing one servo will save you
weight, but TV willrequire powerfull servo such as JR 290G ore Hitec 65hb. If you gonna use one
servo pull pull cables must be crossed in one side of the plane, otherwise motor will move to
oposite dirrection than rudder, and there will be no benefit. Motor and rudder must move to same
possition. If you use two servos you will need to mix rud to TV controlling servo. This way it will b
eeasier to make precise setup of engine angle. Also you will be able to fly plane as with and without
engine movement.
Last step in your plane assembly is also very important. Here you can see my personal setting on
my JR9X radio. Sp far we did building as best as we could to keep plane straight and strong, now
its time to use one feature of radio that will help you to have precise flying plane. Many pilots do not
pay so much attention to triming of plane. Beffore each flight in competition i make short flight just
to be sure plane fly straight and perfect. For this i ned to have precise trims. Arrow surfaces are
really big, and you need to make trim steps as small as possible. Original setup in radio is for 4
steps on each trim click, this is to much for precise adjustments. Here you can see i put trim step to
lowest number possible, one click of trim mean just one step in servo movement.
Last step in your plane assembly is also very important. Here you can see my personal setting on
my JR9X radio. Arrow very easy and neutral flying airplane, therefore no mixes are necessary. I just
put thr curve to 90 percents, to limit amp draw. I have to do this because i use slightly to big
propeller (GWS 8x4,3) than AXI recommends for AXI2203/Race motor.
