I have a friend with a MX20 and while I like the feel of the Tx it has some issues. The travel should be from -100 to 100. My question was when it was flying well, before the white flashes, what changed?

You mean if i change anything in the setup?
The first time i had this issue, i was flying hover a lake it was going in a straight line moving forward and everything was fine, i stopped in mid air and i started to come back backwards, after 3 seconds the s-800 start acting strange and i lost altitude suddenly, i thought it was the end of it swimming with the fishes, i raised the throttle to max and i managed so bring it to land but at all time until i land, the s-800 was moving up and down without any changes on the throttle stick.
The battery was fully charged and i was only flying for 2 min.

Its strange but for me there seems to be a trend ( just a speculation ) that most issues happen with traditional RX.

channel for channel to the MC (PWM) instead of S-bus single cable or PPM single cable.

Does anyone know the dimensions for the DJI cases that the S800 and Zenmuse originally came in? I am looking to get some cases for them, any recommendations?

This normally happens when the throttle stick is near the center position.
This might be a dum question but, with the graupner MX-20, the traveling of channel 1, which is throttle, goes from -100 to 100, shouldn't it be 0 to 100?
Are you using heli mode or Acro mode, There sjould be no mixing in your throttle curve.

Just saw this vid of a 550 with Wookong doing the flips of death:
Seems like a problem with the Wookong, but it's possible he just lost a prop or something...

No Idea about the original cases, but since I just took pictures for someone else...

Quote from my previous post:

"-Pelican 1560 fits the Zenmuse with camera, video Rx and Antennas (flat patch + cloverleaf), Futaba radio
Or
Video Rx and Antennas, Futaba radio, Video goggles, tools, 4x 5000mah 6s Lipos, 2x 3000mah 3S Lipos, cables, etc... (I usually use this, and keep Zenmuse on landing gear...)

-Pelican 1600 fits everything that comes in original cardboard box for the S800 (including grey Polystyrene molds)"

Looks like a sudden dip to the left and then the copter compensated leading to a flip to the right. Most of the FODs with S800s seem to just suddenly flip with no real indicator of a problem. IMO, this doesn't seem similar, maybe a prop or ESC failure on the 550 though.
