  • Learning to do auto's

    How do you learn to do this? Are there any notes to let you know what to do and when. Reading the other posts on running out of fuel has made me worry.

    Mack,

    Auto's are relatively simple, the best way in my opinion is to start at about 1-3ft, have a high headspeed and click hold.

    Tip's are to make sure that your hold pitch curve matches the curves from which your going to enter hold from, thus you will have no sharp changes in the pitch.

    You will wind that as soon as you flick hold, the heli will turn a little as the torque drop's off, and start to drop as the lift is dropping off due to the headspeed slowing down.

    Once you get comfortable with the low end, then you need to get high and fly into the wind and go into hold just as its at 80 degree's at the same time drop the pitch. What you want to watch is to keep the headspeed up as you drop, it will drop like a brick so once you get about 10ft flick off hold and power up gently and fly off back up to start again.

    Do this loads of times until you can position the heli's starting point so that it will land aprox in front of you.

    The idea is that you keep the flow of air going through the main blades the tuning of the pitch as you drop you will easily see the speed either slow down or speed up, try to find the ideal pitch position for maximum rotor speed.

    The piece inbetween the highend and the low end of an auto, is to flare the heli at the last moment, thus slowing the forward speed and but still keeping flow through the blades and as you come to near stop then land.

    In a .30 you can get a small hover, in a .50 bigger and 60/70 more and a .90 its another world.

    I've a movie somewhere of what was my Fury Extreme, doing a bunch of std auto's, I've one of the Milli Pro on the movie that's on the site already. I'll try and find it and upload it.

      Practice loads of Auto type approaches ; ie 45 degree power on approaches to a definate landing not into a hover. then when you can do that consistantly hit the throttle hold switch and have a go.
      You need to set up your throttle hold to take the engine to tick-over that way you have a chance to bottle out and go round again.
      Also set up the throttle hold pitch curves to give you between 3/ 5 degrees negative at the bottom and plus 12 or so at the top.
      When you go for it position the Heli into the wind - it helps if there is a nice breeze - not to far down wind - lower the collective and hit the switch - don't be tempted to push the nose down as this will kill off any rotor speed , and fly it down as you praticed - try not to flare it out to early " you will tend to want to do this"
