#PWM RX not cooperating

im trying to set up independent ailerons on a betafpv 5 channel receiver, but the right aileron is doing something i cant diagnose

#

it seems to be acting on-off, and only in one direction

#

the other aileron is working just fine though

#

Ch5 is a one bit arm channel. Move that to ch6 on the receiver, and select a full res mode in the ELRS lua

bright moat
#

this is a 5 channel receiver

#

did i just buy something i cant use

severe kraken
#

No, remap ch5 to ch6 in the receivers webui

bright moat
#

ill try that

severe kraken
#

In the last screenshot, output ch5 should be set to input ch6 (aux2)

bright moat
#

that did it, thank ye kindly

severe kraken
#

Make sure you select a full res mode in the ELRS lua

bright moat
#

on the transmitter or the webui

severe kraken
#

Transmitter

#

Long press SYS, select ExpressLRS, then set packet mode to Full res 100Hz

bright moat
#

would channel 6 be the reason this servo stops short in the down direction

severe kraken
#

Have you selected full-res mode? Are your channel outputs correct?

bright moat
#

i selected full 100hz, and what do you mean by channel outputs? everything is mapped correctly

severe kraken
#

If you look at the channel monitor on your radio, are Ch4 and Ch6 moving as expected? Do you have any expo or rates set on Ch 6?

bright moat
#

this is getting more into mixing/opentx than elrs, just a headsup

#

i set the weight and offset values to default on the radio and the servos are definitely not centered

severe kraken
#

Nothing in ELRS will change what is output to the servos, so if one servo isn't responding the same way it's coming from your radio

#

Swap servos between ch4 and ch6

#

See what they do

bright moat
#

i swapped left and right ailerons in the mixing menu, they do the same thing

severe kraken
#

Same servo, or same channel?

bright moat
#

the control horns are physically centered and there is enough physical range in the servo, i checked that

bright moat
#

i didnt unplug any servos

severe kraken
#

Physically unplug the servos and swap channels that way

#

See whether the behavior follows the servo or the channel

bright moat
#

seems to be the servo

#

nothing changed again

severe kraken
bright moat
#

im gonna try adjusting the control horn

#

it has extra travel in the other direction i think since it keeps hitting that side of its slot
