Topic: Apache requires 95% collective to lift-off?

With the Apache, I find that I need up to 95% collective just to take off. All the other helos lift off at around 60-70% depending on weight/ordnance. If I hot seat into an Apache already in flight, I have to maintain collective at 80+% just to maintain altitude. Anything less and I eventually start losing altitude. Again, this problem only occurs in the Apache. Haven't checked the loadout to see if it only happens when carrying a lot of ordnance and/or fuel. Has anyone else had a similar problem? Win98SE Celeron533@600 256MB RAM EECH patched, with EEAH installed S.

EECH has air density by altitude. It's described by a big table in a simple fashion rather like NASAs LaRcsim (or just about any other desktop sim for that matter).A full anti-tank loadout does present problems for the Apache (this is why Westland wanted new Turbomecca engines for the extra power since they are required to operate from ships in warm climates). I remember changing one setting in the Apache FM to allow for single engine flight but requiring the pilot to use transitional lift (like in Longbow 2 with one engine out and damaged rotor). I changed a line in the Apache.dyn file to read as following: translational_lift value = 3.000000, min = 8.000000, max = 15.000000, modifier = 0.020000 Although it has the effect of increasing the uplift of the main rotor. Easier one engine flight, more power for two engined flight. I only doubled the last parameter of the line.
