Helicopter Information
Set up and Terminology   Words From the Pros
   

These are quoted from RunRyder jotting on what Curtis Y. and Jason K. said in one event back in 2003, mainly on five topics

Safety

  • Have your eyes checked. If you're having trouble seeing the aircraft through manoeuvres to just flying around, you may just need some specks. If you wear glasses, wear them
  • Flying no closer than 15 feet from yourself and perform no tricks closer than 30 feet
  • Never come screaming in at yourself and pulling up (or down), anything can happen and has.  It is known to have happened that someone suffered serious facial injury by the rotor disk when their helicopter backed into them
  • Several people have been injured from flying debris due to mechanical failure and parts flying off on impact. You cannot be too safe!

What do you want out of flying???

  • First off, if you have three choppers put 2 away….
  • Sims are fine for learning the correct stick movements
  • Practice, I use the term (WORK) no more than 3 flights a day
  • Be disciplined in your flight and practice.  Maintain firm control of the helicopter, use small inputs
  • If you’re happy with your flying great, change nothing; fly as much as you wish….
  • If you want to improve your flying, than it’s going to take work on your part

Heli set up recommended by the Professionals

  • 10°/-10° on a governor in all four flight regimes (Period!)
  • Straight line pitch curves from -10 to +10, linear, not flatting out the middle
  • Straight line throttle curves in normal. “V” curve for idle up
  • Make sure your idle up (3D mode) has an increase in RPM, that way there will be no mistaking you're in the 3D mode.  Normal 1450, 3D 1850 head speed
  • Set your Gyro gain at your flying style.  You don’t need a twitchy high gain setting unless you’re losing the tail in backwards flight.  Plus this will wear out your tail servo
  • Vibration will also wear out your servo and cause premature failure of other mechanical parts
  • Holding the radio: Fingers or just thumbs whatever you are comfortable with as long as you don’t inadvertently input rudder while moving the collective and vice versa...
  • 20% expo at the most for them...

3D!!!

  • Always add collective (Pitch) first! (Period).  Collective, positive or negative, should be added before cyclic to prevent the helicopter from stopping / stalling / hovering in the middle of a manoeuvre
  • Manage your power.  If you add 10 degrees of collective and push in 5.5 degrees of cyclic you will bog down even a YS91 with 15.5 of overall pitch.  In the hands of a pilot that uses power management and collective first the helicopter looks over powered; however, this very same helicopter in the hands of a stick banger appears under powered with slow response due to poor management of power and inputs.  One chief complaints pilots have is “my helicopter needs more power”, so they buy a big block YS80 or OS 90 and still have the problem.  It’s not the power plant it's the flying style
  • Your 3D or cool moves will be limited by your foundational experience.  You can’t expect to fly around upside down if you can’t hover inverted, right….. You must have total control of your helo at any attitude, altitude, or angle before attempting moves like the pirouetting flip
  • Jason said it took him ONE and a HALF YEARS to perfect the Pirouetting flip and the rest of his flying suffered in the mean time, Yeah sure…Suffering for him is like Tiger Woods getting 16 under par vs. 18 under par
  • Say you want to do a pirouetting circles; break the manoeuvre down into basic manoeuvres..  You must be able to input and make corrections nose in, port in, starboard in, tail in etc… before putting it all together
  • Practice an out….An emergency recovery.  Say you’re working on nose in, and you’re up high, if you get spooked add collective and pull out…Practice both ways
  • Always easier to pirouette to the left, unloads the toque.  This was not so before HH Gyros
  • Steer the furthers part of the heli, i.e. “nose in” fly the tail, “tail in” fly the nose...  While up right; however, when inverted fly the closest part of the aircraft…
  • Use your peripheral vision.  Don’t be afraid of smacking into the ground. Judge where your aircraft is in relationship to where you are, the ground, and surrounding landmarks etc..
  • As with any vehicle, fly it! Don’t let it fly you. Use control
  • Practice in-flight failures
  • Don’t practice high risk manoeuvres on a helicopter you can’t afford to fix
  • Practice (work) up high, give yourself time and room to make corrections.  Don’t just “Go for it”
  • When practicing autos bump up the throttle in “Hold” at first and remove it as you become more comfortable.  Dip the rotor disk so that air passes through the disk at a 45 horizontally and vertically....

Equipment

  • Servos and other hardware wear out so preflight, check and recheck
  • The most you can expect from a tail servo is approximately 375 flights...
  • Todd has got as much as 1200 flight on a servo, (not tail)
