Are quad ramps up the power on the throttle without us touching the throttle...... Any thoughts?

My guess would be that something is rubbing on them. Check to make sure the bottom of the spinning axle is not touching anything. 

Are they just continuing to increase or do they level out?

Hmmm.. The flight controller may think that it is falling or tilted. Check the sensor calibration.

Sensor Calibration Procedure: Calculate 
This calibrates what the Flight Controller considers horizontal so try to make sure it is on a flat surface.

I'm having similar issue when the blades are on. 

I assume, for me, that it is because the motors are unstable (The base that the motors are screwed to is too flexible). This instability may lead to the motors ramping up. 

Just a guess though. We are going to do a redesign to see if it will fix the issue.

my quad also spins when it gets in the air and doesn't go straight up..... not a sable take off at all. Not controllable... Any ideas?

We are having the same issue. With the throttle just above minimum it slowly ramps up to whatever the max setting is (ours defaults to 1900). It's very uncontrollable

Now that my motors are bolted down to a better surface I'm not having the issue with the motors ramping up.


You might try to raise the baseline offset a bit higher then just spinning. Check the box to do all motors at the same time and then increase a bit more than just to spin. This may help stabilize their rotation rate.

This step: Output Calibration: Walk through the calibration. Just get each motor to just spin. Be careful they should actually be spinning now. Mine all started at about 1026 microseconds.

If it is spinning around its vertical axis, you may have a yaw offset. 

Check the offset on the handheld controller (Spektrum Dx6i)

The bar on the screen should be right in the middle. Use the switch below the left switch to set it. Click left and right.

(It is actually a good idea to check that all of the offsets are zeroed out before you try to fly. You can adjust these later.)
