Hi
I am at my wit's end and need some help. My quad has an UNCONTROLLABLE throttle.
If I set the flight mode to stabilise, arm the motors, the first notch of throttle will hold the quad just within ground effect. I can confirm that the rest of the controls (pitch, roll, yaw) functions as they should. These can respond to small inputs from the transmitter.
The quad is fitted with Cube Purple flight controller, T-Motor P60A 4-in-1 ESC, four T-Motor F90 KV1500 motors, Here 3 GPS, 6S LiPo, Futaba radio, and use ArduPilot and ArduCopter software.
In the 3 months that I had the quad, I’ve ripped off wiring, broke a telemetry radio, destroyed 2 LiPo batteries, broke two sets of props, and had a flyaway (found it about 2 Km from home, three days later).
I have done the following so far:
I collected the quad and tried to tweak some of the advanced settings. This seem to dampen the throttle a bit, but as I thought I was in the clear, FULL THROTTLE, dragged my tether around for a bit and hit the ground. Breaking some more props.

I have done the following so far:
- Loaded the latest ArduPilot software
- Updated firmware (ArduCopter) on the Cube
- Calibrated the flight controller systems (several times)
- Calibrated the ESC (several times). This was done on the individual ESC modules directly from the RC receiver as well as from the ArduPilot GCS
- Calibrated the power curve on the Futaba radio to MAX 40%
