Stilton, this is a suggested technique:
Apply 95% power (not max pwr).
Apply forward cyclic.
allow heli to accellerate.
top up power to maintain 95% (because TL is reducing tq for your applied pitch setting)
more forward cyclic to maintain disk attitude (overcome flapback)
allow heli to acellerate through 'the burble' (you are flying through your tip vorticies at this point)
heli will now want to leap airborne...
... apply 100% tq (for a clean break with the ground)
apply enough cyclic to maintain disk attitude (this might be fore or aft depending on heli type)
fly away....
Any further questions?
