Hi everyone, as I have said before, I am a Tech Teacher and Tech Club advisor with very little knowledge when it comes to drones. Having watch a multitude of Youtube videos, I have figured out how to setup a 75X to a Taranis QX7. My problem is when I arm, the motors spin up(at low speed). I can take off, fly, and maneuver normally. However, when I throttle down to land/prevent crash, the quad doesn't fully throttle down. Blades are still spinning fast enough that the quad ends up in a wall somewhere everytime. Any suggestions?
