2nd build=confusion

I have built my second quad and its just had me stumped. Its a 3-4" frame from getfpv.com and I dont remember the name of the frame. the FC is an spracing f7dual, lumenier 18A 32bit silk esc's, emax 1806 motors (from the wrecked robocat250 i built), an FS-A8S rx, and im using the flysky FS-I6.
first of all i cant flash it with the latest firmware, ive even tried using driver fixers with no luck there either. I'm not sure what I'm doing wrong.
Skipping past that i can connect the FC to cleanflight and dabble with the settings but I'm just not sure what I'm doing. for a moment i had the transmitter responding to cleanflight, and now it wont. im sure its bound to the receiver because it gives me a solid light when I turn the transmitter on.
I wired the FSA8S to use SBUS/IBUS but cant seem to get the motors to spin using the transmitter, they only spin in cleanflight calibration. yes Ive tried the arm switch setting. Im frustrated.
 
Suggest contact getfpv support try to get a live chat going with them to see if they can help you with the issues. Want to break things down to take them on one by one, I'd start with the firmware flashing since ideally first thing to do before setup but you need to select the correct target and may need to select full chip erase or other options to get the firmware written fresh. Regarding driver fixer stuff that is just to get the com port to show up in windows, the issue there is windows picks up wrong drivers for the usb communication chip on the FC usually a silabs (silicon labs) one or a cypress I believe, but anyhow usb chips that need correct drivers for com/serial port to show up to windows. If you see that com port in device drivers then driver fixer worked or you have correct drivers. Flashing is a more advanced topic and so may need some hands on support, in general you don't need to flash the FC when received it should be ready to configure but nice to be able to flash updates or back to default firmware if something goes wonky.
 
I got the radio controller to respond in the cleanflight menu, possibly a combination I have yet to try. all I did was disable telemetry in the ports tab, I'm using uart 2. still however, there's the issue with the radio controller not spinning the motors. my fs-i6 controller will also not bring up the binding screen when i press the button. I do think the fs-i6 and fs-a8s are bound together because when the radio is off the rx blinks, when I flip the tx on, the rx led remains solid. Im still wondering what the issue is, and thinking, maybe go back to the other rx i was using but it is physically too big to fit in a clean looking spot on this quad frame. thanks for the help.

In the modes tab did you make sure a switch is set to control arming? Also it won't arm if usb is hooked up or throttle above 0
 
yes my aux1/ ch.5 is for arming and it works in the tab. im getting arming flags of 6 and 10. this is with or without the usb plugged in, but most importantly when im not plugged in to the usb port. For some reason it isnt arming and the nice video i just watched doesnt have the issue. I have lowered cpu load, disabled accelerometer, its level, my throttle is set correctly, the aux1 is in the range to arm, etc.
 
i dont have failsafe enabled either, and I think that is one of the flags saying its enabled. i really just need a good walkthrough on how to set this up but there isnt one for cleanflight.
 
If you're have option of saving blackbox logs do that and dump them here after trying to arm the logs should say why it's not arming
 
Ah yah sorry not sure with CF either only used BF a lot but know BF was fork of CF didn't really know CF continued development though since most pilots I think switched over to BF
 
I soldered my bad connection and it all works but seems as if the motors are not calibrated or i have a funky setting somewhere. it wouldnt even take flight. it just spun in circles.

^^ should support both based on this page most things that will run cleanflight will run betaflight no problem, I think emuflight or iNav are both more limited with regard to board targets that they support without a ton of fiddling but BF and CF are closely related.
 
interesting, when i try betaflight an error message says something about unsupported firmware. i was getting farther with cleanflight. its an SPracing f7 dual so i beleive it was a cleanflight specific FC.
anyway the quad is up and "running" it just wont fly, my motors seem to calibrate just fine but the radio transmitter seems to have a need to trim excessively and isnt very accurate. one of the motors is also way slower than the others and if not ramped up very slowly it will just kind of chitter along. All i get out of the quad is a spin on the floor.
What i want to do is buy some quality 1806 motors or another motor that fits the frame, and get a better quality radio transmitter. I am hoping this at least solves the inaccuracies.
 
If one motor inconsistent try resoldering connections for that one motor and make sure screws holding it in are secure and not jamming into the motor windings.
