Hey guys,

First time poster, long time lurker. The advice here has helped me get my quadcopter off the ground and crashing back into the ground countless times.

I finally created an account because I've encountered a problem that doesn't seem to be addressed here.

I recently crashed my quad pretty bad. The Eachine 250 has the PDB integrated with it's body. I ended up cracking a few points that I've resoldered (and covered with liquid tape).

I destroyed an ESC and decided it would be a good opportunity to replace all the motors and ESCs. I went with 20A littlebee esc and emax rs2205 2300kv motors.

Onto the issue: After setting up my quad using the Setup Wizard, I am presented with controller setup.

I turn on my controller and am able to pass through most of the setup process right up until the end when I need to wiggle my joysticks around to their maximum thresholds. My sticks lay motionless, no matter what I try, I cannot get them to move around on the screen.

When I completed the setup and loaded up the quad, it wouldn't arm.

So I disabled the disarm (leaving the quad armed when plugged in and connected to controller). When I plugged it in, the quad went NUTS, full throttle! When I moved the throttle stick upwards, it seemed to actually slow down the props (at half way on controller) and then back up to full speed (full throttle on controller).

Here's the video: http://recordit.co/55SStlr9Hf

Any ideas what may have caused this? Have you guys experienced anything similar?

I'm thinking of getting a new receiver, I'm thinking maybe I screwed something up with the crash.

About the motionless stick - Transmitter Wizard issue you can take a look here:
https://forum.librepilot.org/index.php?topic=3156.msg21834#msg21834

This occurs when you skip the flightmode detection step.

You can see the issue described in some recent posts :

Nailed it! Thank you so much!!

The solution:

My eachine i6 controller was not programmed to use the flightmode stick (so it failed to activate when setting up librepilot).

The "bug" is that without a flightmode switch, no flightmode is set and it won't detect the maximum distance for my sticks.

Glad you finally found the solution following the links and instructions ;)

Min and max values are perfectly detected if you physically move sticks when asked.
