Ok just put my expo in and went for a test flight and while hovering inverted the heli didn't have enough lift to maintain an inverted hover. It would slowly creep down towards the ground, not enough negative lift. Any ideas where I could start to change this. Thanks again!

I forgot to mention i'm using a DX7 my pitch curves are 0-25-50-75-100 for ST1 and ST2, my throttle curves are 100-95-90-95-100 for ST1 and ST2. Thanks

sounds like you pitch in negative range is not the same as your postive. Check your pitch ranges, make sure it is set mechanically linear.
Meaning place a pitch gauge over your blades and check mid stick (0deg)
Bottom stick (Looking for -10+ if you can get it)
Top stick (10+ if you can get it)

-10,0,+10 is a good range and wont bog the motor so much

Yep, you must not have the head setup right....with the linear curve you should get at least +-10 or 11...

Use a pitch gauge and check your negative pitch.

Ditto on the above.

What is the pitch in degrees on the negative?

What he said^^^^ sounds like you need to get zero set at mid stick!

ok...I'll have to check it out. I didn't bring a pitch guage on my deployment. I'll see what I can do and get back with you.
