Quanum Trifecta


Hi folks



i worke on a smal solution to build out of a trifecta a mini mapping drone.

i use the new Pixracer and the frsky xsr reciver

the motors are babybeast multistar.

tailservo sav÷x sh0263MG

afro opto esc 12A

200mw fpV with cemos camera tvl 600

3S lipo

second camera will be a gopro for easy mapping (not best for this but worable)







but some problems coverd my way i need help with the PID understanding in general
also the working with the new arducopter software is no easy.

Love the modeled top rack! Do you share the files for it?

Any lucky?


Hi Zaam,

any lucky with PID ? I bought a pixracer too and wish to use with trifecta but I couldn't find any clue about pids.

regards

I bought a Trifecta quite a while ago in the hopes I could take it with me when I travelled for work because it folded up. I've never really ever gotten it to fly right.

Ditto. Bought one off a user on here. Tail assembly has a lot of slop, arms don't lock that tight. It was cheap enough that I don't feel bad junking it and using the electronics elsewhere.

I have a trifecta setup with SPF3 board and triflight. I documented the build process on my blog here on RCGroup in case you need some help. Main thread link HERE

I'm gonna be using betaflight and the XSRf4O

but I'll be checking out that thread.

I'm aiming for low weight ...although I am gonna be rocking a 1300mah 3s graphene ...which tend to be a bit heavier than similar mah nano-tech batteries.

Wont have the frame though for a number of days since it's on a boat right now.

My trifecta was really flying pretty well with Cleanflight,
but with pixracer I cannot takeoff.

Spent today wiring up my power distribution board and esc's etc. Basically everything to the point of connecting the flight controller.

Seems like my fc's dimensions dont match up to any mounting holes. So i'm gonna have to get creative on mounting it.

Everything else is coming along nicely though. Construction is tight. Tail motor swivels nicely. I wish the thing would mount on some of my better actually 9g metal gear servos but it seems specifically designed for the 9018mg head vs the others i have.

Hi!

i cannot make Triflight .7 beta3 work with Quannum Trifecta and cc3d and cheap MG90S analog metal gear servo

by arming servo twiches fast between all limits
00021 (0 min 25 sec)


When giving 60-80%+ throttle twitching starts to reduce greatly and almost flyable:
00022 Triflight cheap MG90S analog servo twitching (1 min 49 sec)

Hi, Guys!

I have 2 similar Trifectas (now one is flyable). I use FLIP32 Naze F1 controller, my firmware is cleanflight 1.13. Its PID value of YAW is most higher than Pitch and Roll values (4-4-8.5!) like Triflight's ones... I use plastic analogue TG9 servo. I noticed, that after takeoff the servo began to alternate with cca 1 Hz freq..... I set PID values of YAW the same as values of Pitch and Roll, and after this attempt the alternating eliminated....

What do You think about this symptom? Why do YAW PID values higher than another one?

Thx: rcph

Hey, I need some stable firmware/settings could you drop me your settings? I have CC3d that could be an issue....
what I saw just to answer your question YAW P was way high by default at 0.6 triflight (cleanfligh based FW), in 0.7 which is beta based it is less.

Could you send me your firmware version or better to go to CLI and dump all setting and select and paste all things to a txt file and send/attach here?

For me all triflight 0.7 were do yaw twitching at zero throttle, but tri_yaw_boost setting set to 100 or less it was eliminated but also YAW stabilizatio is eliminated so unflyable
I flashed than triflight 0.6 and now it does not arm even if arm flight mode is active I don't know what to flash next
