Thanks for the quick reply Chris, ive just read the following instructions on thier forum:-
The Procedure:
Fly a standard pattern, 500 AGL and 80-100 knot airspeed. Line up on short final for the desired runway, check that it’s clear, and within your glide range. Press Ctrl+F1 (or the previously mentioned joystick button) to roll off the throttle and smoothly, but quickly, lower the collective fully.Here’s where we run into a glitch in FS2004, immediately after lowering the collective you have to bring in about 10-20 % up collective otherwise for some odd reason the rotor rpm will quickly degrade and will be unrecoverable. This is totally unrealistic, but is the only way to make it work in FS2004.
It did work but with quite a bump 😳 and like the guy says "unrealistic"
If this is the way its done in FS2004 than so be it, but im open to any more suggestions from any desktop helicopter pilots
many thanks
