Triflight setup guide

[Ralph]

Oh damn, I thought the smaller filesize and missing 0.3 may had a older link in your guide.
I have to apologise for that misleading.

Guys, my setup is stock RCE Mini, including electronics sourced from RCE. I have 2 2015.6 DYS ESCs (LH and rear) and 1 2015.10, all running BLHeli FW14.0. Naze3 FW is Triflight 0,3. Followed Leo’s setup guide, although I only did the tail servo setup by eyeballing it. The mid setting is set to have the tail motor vertical compared to the airframe, and the mid and max to have a symmetrical deflection from vertical. I etsimate it to be around 40 deg either side of vertical.

I fly in angle mode and the response with the stock PIDs is vry crisp. The one issue I have, flying Los, is that it yaws right when flying backward. By about 30 deg I would say. Going forward it yaws opposite direction, but less. This makes it hard to fly LoS, as you lose orientation pretty quickly.

I thought I saw some posts describing similar behaviour during early days of MiniTri flying, but can’t find it. Is this behaviour due to imprecise tail set-up? Should the ESCs be configured in main/tail or multi, i.e. Should the tail motor be different?

Thanks Leo for your guide!

I found out some interesting behaviour of my tail servo today.
Are you guys configure the servo in cleanflight with “live mode” when the board is ARMED?
Because I did it not armed and the setting are totaly fine… got 40° deflection on both sides, but if I arm the naze32 and leave it right on the table where i calibrated it, the servo is a little of center and the deflection on the left side is way less then 40° but on the right side it looks alright.
Is the behaviour normal? I couldn’t test it so far.

That’s normal, the FW is limiting the angle on the left side as on that side the motor torque is helping with yawing. On right side the thrust is fighting against the torque and we need greater deflection angle. That’s also the reason why the center position is a bit on the right side.

[Ralph]

Well that makes truly sense.
Thank you @lauka for the good info.

Hey Guys,

Is there a Triflight .hex file for the SPRacing FC?

Or if it’s Naze only will it work on a REV6 or 6B board?

Thanks!

[lauka]

SPRacing target exists for 0.4 Beta 1 in https://github.com/lkaino/Triflight/releases/tag/0.4-beta1.

Haven’t tested on naze rev6. I believe it requires a merge from Cleanflight.

[SMJ]

Thanks for the link!

Hi Guys,

Just about to give it a go (on a SPRacing Board)
Is Cleanflight configurator 1.1.0 OK to use for setup?

Cheers!

Anything newer than in the guide should work.

To set up the “Seriously Pro” Racing F3 board, have a look at this post to get you started.

[SMJ]

It’s in the Air!
Just have to spend some time on Black box and lock it in!

Thanks Guys!

[Terje]

Blackbox is always on unless you define a switch to activate it.

You can at least increase the the P’s by 0.2, double the roll and pitch I’s, and 20x the yaw I from default.

[SMJ]

Yeah I have it on a switch. 🙂
I need to fine tune the yaw angle.
It was on 400 (set for 40 degrees) but my tri (own design) can currently only get 32 degrees. Im changing the yaw mech to try and get 40.

I have to check my servo speed too. (Hitec HS81)

Its all coming together…. 🙂

[Terje]

I did some notes on setting up the servo.
