First Build UAVFUTURES $200 build issues, please help!

Hi, i have bought all the parts and configured my first Quad via UAVFUTURES' $200 guide (Upgraded version).

Links found here:
And

I have been having some issues with getting my quad to successfully arm and respond to the throttle,
with it being configured in Cleanflight, as by following the guide.

My rx and tx can connect to each other and toggling the arm switch on and off causes a red light to flash up on my FC, but my motors won't spin up or respond to the throttle.

Could anyone help me out here?

Ps: If you are also following this build guide and are stuck on connecting to betaflight/cleanflight then this
video should solve your problems.

the arming may be due to the default for arming angle in config section is set to 0. Change that to 15-20 is your being safe and dont plan on trying to rearm in a tree or something to get it out. I set mine to 90 so that no matter what angle the quad is at it will arm. Be careful in this config, set up a pre arm or something if youre worried about accidental arming.

I can't seem to find that setting in the Configuration tab...

I also tested the motors in the motor tab by arming the Quad with the Receiver and using the sliders in Cleanflight, so the motors don't look like the issue..

Any other advice?

In the OSD settings you can enable WARNINGS, also make sure in the modes tab you have ARM setup.

The WARNINGS display will typically show you either you throttle is up or your arm switch was on when it was turned on and needs to be toggled off then on or it is tilted as the other forum member posted.

Not really sure why, but now when i toggle the arm switch the right two motors start spinning but not the left......

And when increasing throttle nothing happens =(

Also there is response in the receiver tab with the aux channels etc

And my FC doesn't support OSD

Sorry for the choppy replies

Update: Super inconsistent spinning when armed between all 4 motors, i'm guessing dodgy soldering?

And increasing throttle still has no effect

Right! After a bit of tinkering, i reversed the arming channel on the Receiver, which means that it starts armed (which is a tad unsafe) but now responds to increased throttle when without the reversal it doesn't. Not quite sure what's going on here but at least i can control the throttle!

Arming switch should work in either position but would check out the solder connections around the escs and either heatshrink them onto the arms or electric tape them down including the wires. Don't go too crazy with covering them since they need to dissipate heat.

In the modes tab, does the slider move into the range for arming.
If you reversed a channel, did you do it on the tx. My arm is on SWD which is a 2 position switch on channel 5.
Just move the sliders in arm tab so the range is covering the right side half.
Or you could make it tight on it.
But should be no need for reversing.
Reset the model on the Tx & start fresh.
Does failsafe work o_O
2 motor not working
Solder connections & esc endpoints not matching in blheli or what is in the configuration tab.
I just got the F411-wing & for some reason the board needs a flip before I put my -90
on it. I had an omnibus that needed this doing & it had me stumped for 20 minutes. It was like the gyro was put in upside down. In inav even though you set your direction, the calibration goes off the original default.

Right! Apologies for the looong delay, but i have done multiple test flights and my quad appears to work as it should.

The failsafe does work, with the motors powering down after loss of connection.

But i am still rolling with the reversed arming, using the switch to deactivate the quad when things go wrong (crashes, breakages, etc).

The primary issues i've faced when building this quad were with Cleanflight/Betaflight and the arming/failsafe functionalities, so if others have these issues too (i guess) try what i did.

Thanks all for the help, it is greatly appreciated!

(I do have an additional issue, regarding my camera -> vtx -> Goggles connection but i will make a new thread for that.)
