"If you engage RTL when the aircraft is on the ground the Flight Controller will automatically detect "landing complete" and disarm the motors.
If you can, use a switch to trigger RTL (channel 7 or 8).
Fly the aircraft away from the launch…"
"Give us a SPECIFIC, DETAILED break down of what you are using for motors, batteries, props, plus any extra pay load (camera, gimbal, FPV gear, etc.) the aircraft is carrying, and an accurate aircraft weight WITH EVERYTHING installed.
While you are…"
The motor order in Motor Test does not match motor number.
Motor Test starts with the RIGHT FRONT motor and moves clockwise, so for a Hex, Motor A is Motor 5, Motor B is Motor 1, Motor C is Motor 4 and so on."
"Some other things that can jump up and bite you:
1. RC_FEEL_RP, particularly when the aircraft is overpowered (hovers below 50% throttle).
2. Autotune. I prefer using In Flight Tuning. I ran AutoTune on a quad that was…"
"You're just staying on the ground too long. Flybarless helis do the exact same thing.
The problem stems from the fact that as soon as you arm the motors, the flight controller is trying to keep the airframe level.
A flybarless heli gyro…"
"Pixhawk doesn't care how much the aircraft weighs, What you need to be concerned about is the power system (motors, props, ESCs and battery) that will give you at least 30 kilos of thrust at 50% throttle. This comes out to…"
"I had the same issue with a FlySky TH9X with an XJT module and an X8R receiver.
Short of installing a Smartiparts 9Xtremem and flashing new firmware, the easiest way to "fix" this is to use a PWM to PPM encoder.
"That chart still does not tell you what the thrust values are at 50% throttle, and because the physics are not linear, you cannot interpolate thrust at 50% based on thrust at 85% or 90%. In fact, full throttle thrust is pretty much meaningless…"
