I need description and 'know-how' to make a new auto. It is one maneuvre very hard to me. I also need some advise about steering at autos. Because now I can do it only straight way

Many thanks

Maciej

Auto with 2 90 degree turns
Auto begins (Motor off) downwind at the centerline. Model flies parallel to the flightline and descends 1/3 of the height, turns 90 degrees in toward the pilot and descends 1/3 of the initial height, turns 90 degree into the wind and descends the final 1/3 height to a spot landing on the central helipad.
Turns require both roll and tail rotor commands so a driven tail is pretty much required. Try to make each segment appear exactly the same distance so it is symmetrical. It's not hard to do, it's hard to do correctly and land on the spot.

Thank you, And how about the position of model. Should it be positioned horizontal ? or a nose a bit higher ?

is -2 - -4 degree optimal?

Position
Nose level is normal but you can be level or nose up depending on the forward speed you are carrying. I usually use about -4 but can go more negative if the wind is holding me up or go a little less if I need to stretch a leg somewhat.

Motor can be dead or in idle when auto starts, yes?

New
New for this year, the motor must be reduced to idle before crossing the centerline.

From FAI for P-10

"MA flies at a minimum altitude of 20 m. Maneuver begins when MA crosses an imaginary plane that extends vertically upward from a line drawn from the center judge out through the helipad. MA must be in the autorotation state when it cuts this plane. The engine power must be reduced to idle at this point and the MA must be descending. The first 90º turn must be made after the MA has made 1/3 of the total descent. After this turn the MA must fly straight before the next turn is made after the MA has made 2/3 of the descent. The MA then flies straight down to the helipad. Each leg of the maneuver must be a minimum of 10m in length. The descent rate must be constant from start to a point just before touchdown on the helipad. The flight path of the MA must appear as an open square when viewed from above, starting at the vertical plane and ending at a line drawn from the center judge through the helipad."

And do You think that 5000mah 10S is enought to fly it pretty safe?
