Hello, last year I bought a tricopter v3 kit and it flies really nice (with APM FC..)
Now I’m drawing my own 3D printed mini FPV tricopter and I came across this forum searching for the correct firmware to use (triflight based on betaflight).
Now my doubts..
I’ll like to use an Omnibus F4 FC and I saw here that there are some problems on making servo and motors working correctly..
I’ll like to use this FC for its all in one (available UARTs, OSD and other things)..
My guess is to connect Frsky RX, mini GPS (for telemetry log position), tail servo and FPV CAM tilt servo.
I’ll like to use the feedback modified servo available on this shop.
Do you think I’m going to have a lot of headakes?
Thanks for any help

I am considering the F3FC option with baby PDB and a diatone a VTX/OSD combo.
Does F3FC have pads available for SoftSerial?

How many serial ports to you need?? There are three standard UART ports. The way I have my F3FCs set up is 1)OSD 2)RX 3)Openlog (sometimes GPS just for fun) . There are 6 PWM channels, so if you are running a Tricopter, that should leave 2 channels for another soft serial port.
EDIT: I also have one of those Diatone OSD/VTX units, but have struggled to find a camera in my mix that works with it.26 May, 2017 at 21:39 #37779
I’m a lazy man and I like to flash and configure basic things with USB, then use Bluetooth module and this is a serial occupied
Then Sbus/Smartport ant it’s three
GPS to register thelemetry on Taranis (If I loose my beloved in the wood) and it’s four
then OSD and 5!
I think I’m going to use softserial for GPS and OSD as they don’t need high baud rates
For my CAM, I’m planning to use a Runcam Micro Swift, any experience with it or any suggestion for a different VTX/OSD??
I’v got “lot” of room27 May, 2017 at 22:33 #3779129 May, 2017 at 08:26 #37805
do you need the telemetry if you’re using the OSD?? or use the betaflightf3 which I know one of the other guys beta testing triflight 0.7 has worked out the servo port and setup for it29 May, 2017 at 08:36 #37806
I like Telemetry on Taranis because I can register data on SD on Taranis itself.
So for example I can log GPS fix that gives me last valid position in tricopter lost event..
Thanks for suggestion.29 May, 2017 at 09:05 #37808
wow didn’t even know you could do that 😛29 May, 2017 at 09:07 #3780914 June, 2017 at 20:31 #38131
Also what is nice about having telemetry on the Taranis, with an OSD, is you can put on the battery sensor and get per cell info. I would just want battery, artificial horizon, and if I have a GPS distance and direction to home on my OSD. So having the rest of the telemetry be communicated through the Taranis means less info to show on OSD, less clutter in the way of the video.
I need to rebuild my tricopter now that the naze32 is losing support. Plus it could benefit from dshot ESCs instead of old analog ESCs. Thinking of getting the tail mechanism from here with the servo with feedback wire. Checking out what my options are for FC. I would like a decent amount of UARTs. Frsky RX, s.port, GPS, OSD, and Unity SmartAudio. So that’s 5 UARTs. I have a sonar unit if I could get 6 UARTs.21 June, 2017 at 19:53 #38320
I have been looking into this. So many new FCs out there that betaflight supports that triflight could use an update for.
However, for the beta2 supports it seems like my best bet is
CL_RACING F4 AIO
It has built in osd. However, it looks like there are dhost and led strip problems that will be fixed in BF 3.2. If I was to wait that long I would get the Matek board as it has built in OSD and 5 uarts.
This isn’t out yet but has osd and vtx built in with 3 uarts.
For you European folks this looks like a good possible way to go
It looks like my other alternative with what is currently supported and currently available is
So now the next question. How do you know what EXT1 is? Where do you hook up the feedback wire?
