I'm using the settings suggested in the instructions for the T-Rex 600N.

Thats what I did with mine( Use the setting sugested in the Heli Bible) and Be Certain that every thing is at 90 deg. in the linkage All the way Back to the Tail .Fold the rotors over and center them and set the Servo horn up to 90 After you power it and let it find center affix the servo horn and be certain nothing moves when you push the horn on and screw . leave every thing untrimed in the radio or zero .I have mine set up with No Expo or D/R But I like my tail Snappy and fast and to stop instantly ....So you should end up with say 70% gain in heading lock mode and 29 or 30%gain in Rate mode . I had not 1 problem with it I have the 8900G servo is that what you said you have? Make sure to use a regulator its a Power Hungry Servo:thumbup:

I set per instructions for the 600N - 11mm from servo center to ball link
140ATV on the futaba 7CHP, 20% gain. rock solid.

Actualy I was quite blown away with the G7703D and 8900G Servo combo.
I had tried the futaba's each one the 401 and the 611.with matching servo's.
Outta the futabas I liked the 611 the best.Once you understand the menu its easy to set up.The 401 was quite tame smooth and very reliable but did not hold well in backwards flight.
Each of these combos I flew every day for a week.
Then I set up the G7703D and 8900g on the heli. Whoa ! I was blown away by the way this thing works and how well it does it.........You just got spend some time and Get it set up as perfect as you can and set the Gain for each mode get it to hold right .
Land go have a smoke or something ..Come back and start getting the Dual Rate and Expo Dialed in to when the thing works with what your comfortable with( Rate of piroette and stopping speed.) I can have docile and slow will and gentle stop ,You just have to dial it in right .Or you can have Blinding fast response with It hit a brick wall kinda stopping .Andthat thing hold in wind tail slides backwards flight forwards ,It it very solid and very predictable ,once you become friendly with it ...........You can not beat this set up ,I am sorry to say the only thing I have flown that comes close is the 611.
But I have only flown 3 different gyros ,401,611,770 :smokin:

Is the 770 kinda like setting up a 401? just adding 140 or 150 on the end points? :confused:
Im using a futaba 9C radio
