It should have 3.1 loaded on it if it's brand new. If not, update the firmware to 3.1. I'm in the process of doing a complete video series on the 3GX V3.1 right now. One member on here has taken the settings that I have been playing with, and he states that his heli is more stable than ever. Just remember, when you are on the ground, don't go moving the sticks all around. Your swash has to be perfectly level for this gyro to work correctly.
Moved to the correct forum. We don't allow tech questions in the lounge. Thanks.
