I think you need to 180 the plugs black s/b on the outside. Str is for the servo, Thr is for the esc.

Black wires to the right. So turn each plug around.
That is not a Dumbo receiver in the picture. Post a picture of what you’re trying to do with it.

That's it, you want black on the "-" negative and white on the "s" signal.

The dumbo is different from others, the top two are throttle and steering. I THINK the top one is throttle so try that first. Then switch them if it doesn’t work.

1 to turn (servo)
2 to burn (esc)

you need to switch your fan and steering connection .... fan goes to AUX and your servo goes to STR

I just came across the same problem the throttle it's #2 for the steering it's #1 (the brown yellow black one. And put the fan on #3 and on my dumborc x4 I just turn on channel 3 manually to have the fan running. The slr300 that the big rock came with had the fan on AUX which was always on. You just have to replicate that.
