Hi Ross,

i found some writing about this topic in Peter Lovegrove's GYROPLANE MISCELLAVIA, book, volume 5.

I think its available through the ASRA library, otherwise I'll see if I can get permission to scan it and email it to you.

As long as you are doing something that is regarded as being in the best interest of the person you are assiting... if you are not, then you are placing yourself in a legal situation. Our instructors have been issueing this advice for the last 3 years. I'm taking there advice as something well intentioned.

OK Ross,

I'll put it back on track for you:

G 2066 [when in flying condition]

EA 81 Powered Bensen Derivative - with 2.1:1 redrive and 72 x 44 timber prop, has a horizontal stab as well and is CLT as near as zip.

Do preflights - check fuel, oil, water, bolts, nuts, wires, tyre pressures, etc, structurals for cracks and everything else.
Do nervous wee...
Do preflights again in case you missed something the first time around
Put your PPE on
Sit in the seat and buckle in
Set altimeter to current altitude
Check freedom of movement for rudder, joystick and all other things.
set ignition switches to on, fuel pump on, instruments on
" Clear Prop" & Start engine and note reactions of same - idle usually about 1000 - 1200
Check oil pressures, rate of rise in engine temp, oil pressure wrt revs 80PSI @1200 cold, 75 hot
Allow it to warm up and check responses through warm up process
Feel for undue vibrations and listen for unusual noises - taxi to edge of apron to wind up rotors in safe location
stop and park with nose into wind, stop engine, lock stick in forward position
unbuckle and remove + secure rotor strap, get on seat and pat rotors up by hand
Sit and buckle back in to seat when rotors are about 60 RRPM and release stick lock, gently pull stick back to full back stick - if no wind move off at *walking pace* only and enter run way after lookout - clear, plus announcing intentions [location traffic - G 2066 entering and backtracking runway 27 for take off and circuits - location traffic]; if wind then allow rotors to achieve best RRPM for wind conditions and then move off per no wind situation, backtrack to downwind end of runway with forward relative air speed = walking pace, allow rotor revs to build, allow for braking or like at end of downwind backtrack.
At end of backtrack pull joystick back for brakes and then tilt forward and into turn, round up to point upwind and alllow rotors to regain lost speed by pulling stick gently back to full back position, hold position at side of strip and announce intentions - [location] G 2066 holding runway 27 for intended take off - building rotor speed [location].
When rotor speed is maximised wrt wind, announce [location] traffic - G2066 rolling runway 27 for takeoff and circuits / whatever at altitude [location]
***now the tricky bit for the inexperienced - don't do this without instructions! *** bob.
once the rotor RPM has peaked begin to gently increase the throttle, about 20 RPM / s until the machine starts to move forward [about 1400 ~ 1500 RPM], allow rotors to accelerate, watch to your right to see if blades are tracking properly.
As the rotors accelerate progressively feed in more throttle, about 50 RPM / s increase rate and make sure the rotors follow this increase. [If the machine starts to rock from side to side you're pushing it too fast too soon - push joystick forward and ease off the throttle and start all over again]
The rotors will accelerate slowly at first and then will achieve about 180 RPM within about the first 30 s, at this point the nose will lift and you will have full rudder authority.
Once the nose lifts gently push the stick forward and follow it with a much faster throttle increase - about 200 RPM/s increase rate until full power is reached ~ 5400 RPM, hold the nose down with the joy stick so the front wheel is *just* kissing the ground.
As the speed builds to 38 ~ 40 kts you will lift off in a level attitude position, hold this attitude until speed builds to 55 kts
ease stick back and allow climb out at 50 kts at full throttle until desired flight altitude is reached, then ease the throttle back and nose down until cruise speed and altitude is achieved.

Hope this helps - but don't do it without prior flight instruction by a qualified isntructor.

Cheers,

Nick.

Thanks Nick
What I have been trying to demonstrate is that there are different techniques for different machines, and yes individual pilots also vary their techniques to cope with local conditions etc.

If your game, how do the tecniques described above vary from yours???
