Roll on lift off.

I have the quad sitting next to the computer, props off.

If I connect the battery and then the USB, then connect into the MegaPlanner.

Switch in flight mode.

If I arm the motors (low left) the green led stops blinking. Throttle up spins up the motors, but the artifical horizon rotates up to 45%.

If I reduce the spin, the AH gauge levels off. The faster I spin up the motors, the faster the AH rolls.

Any idea what to check for?

If the soldered pins between the gyro and the micro were poor, that could cause this effect.

I'll try this tonight.

Wow. I just got the new IMU and the difference in response is night and day.

Both the gyro and the mag were really noisy. When I first started up I thought it was broken because the mag didnt vary by as much as 10 +- and the gyros traces were all over the map.

Recalibrating and rechaging batteries, then flight time!

My problems lay in the IMU. Both the mag and gyro respond smoothly, with out the jitter.

Now, no problems lifting off. A few hard landings, including the one on the roof of my car.

Thanks all!
