I have flashed the new control 8 onto my baby trip and my V3.5 integrated naze
Only had chance to of hover tests on both, with the baby if i do a little punch out and chop the throttle the tri does a 90 deg left yaw, tail tune was completed not sure where to start
for the v3.5 just a bit of advice check your board alignment in the configurator and check that when you tilt the copter the animation does the same
On the v3.5 I am having some trouble with the bench tail tune, I have finally installed a feedback servo but when doing the bench tune the servo goes to the left back to centre then I get a long beep, might be my fault as I do not have the template and have set the end points by comparing to the baby tri and trying to line up the baby tri tilt tool
at the moment it hovers but has a lot of pitch/roll oscillation

Just flashed v8 to my tricopter V4 and it seems pretty nice. I am having the same behavior that @biggestRCEfan is having where sudden yaw input leads to significant pitch deflection. When airmode is off, the pitch deflection due to sudden yaw is much less, but as a consequence, when I punch out, I get un-commanded pitch deflection. Kinda interesting. Anyway here is my diff and I’m working on acquiring a datalogger.

Wynn, this is not what I have with V8. What you describe I had with the basic 0.7 beta 2. With V8 mine is near perfect.22 September, 2017 at 23:17 #39627
@wynnsquad: try lowering the
tri_yaw_boost. It defines the maximum yaw output. With smaller value it will generate less movement on the pitch axis.
It’s also possible that your servo angles are a bit off.23 September, 2017 at 03:30 #39630AmbroseParticipant
Hello everyone, i have an eagle tree vector rcexplorer v4 and i’d like to know if anyone has any recommended pid values, gain values or tuning advice to make my tricopter fly and hover as stable as possible. also the tail keeps drifting the entire copter to the right without any input from rudder. Any help or advice is welcomed. Thanks
Ambrose.24 September, 2017 at 20:08 #39643
@ambrose: what version of the FW are you running?
It should not drift in hover. Have you checked the centering of your channels?
Any more experiences from the v8? Thinking of making the beta 3 out of it.24 September, 2017 at 22:46 #39645wynnsquadParticipant
@lauka Thanks for the tip. I’ll try lowering the
tri_yaw_boostparameter and report how it goes. I noticed that my
tri_tail_servo_speedwere both quite a bit higher than RCEfan’s (possibly because I’m using 6V on my servo?) so maybe that explains why my yaw is acting so much more aggressive in comparison.
@biggestRCEfan, sorry about that, looks like I misread an earlier post!25 September, 2017 at 05:06 #39648fomoco_44Participant
I’ve been flying V8 on my MiniTri but have been battling a tune issue so I hadn’t really got around to posting feedback until now.
I still have a lot of oscillations on the yaw axis which I think is also showing up the roll+pitch, I’ve already dropped the yaw P to half of what the V8 defaults are, and was planning to half the yaw D for the next test.
From my experience, the V8 code feels great from the yaw control point of view. Yaw authority at low throttle is great, and flips and rolls are much more predictable than previous versions. I Like!

On a side note, is there a limit(s) or validation on the in-flight TailTune that prevents it from saving??
I have a Quanum Trifecta with an F3FC on V8 and Savox SH255MG servo(with feedback) which i can get to tune inflight no problems, but as soon as I land(and disarm) it the tail servo wobbles violently and I get the 2-Beep failure notification…..even though I was getting the success beeps in-flight. Thrust factor remains at 54 so I’m positive that the tune didn’t complete properly.
I was thinking of enabling the servo lowpass to reduce the servo wobbles from the structural mode issue, as per this:
Any thoughts?….I was hoping to get the Trifecta working so I could help fault-find the MiniTri and also confirm the benefits of the new V8 code.
Another side note…..for the Trifecta the servo mechanisim is via gear drive, so I’ve had to use the CLI smix command to reverse the servo direction. This works fine for normal flight, however during the bench tune the servo direction is still reversed. Not a big problem, and the tune still works and saves correctly, just thought I would let you know about it in case it was an easy code change.23 October, 2017 at 17:51 #39932
Could I get this build for KAKUTEF4 because I cooked my last f3FC and I wanted something a bit more simple to work within the terms of soldering.
Stephen29 October, 2017 at 18:35 #39962
Hi I managed to install triflight beta 2 to the KAKUTEF4
I set the servo to motor 6 pin seen that was using a different timer
so I used the below command
resource servo 1 c08
Then I solder the feedback wire to the RSS pad and then had to set the feedback to look at it
set tri_servo_feedback = EXT1
and I had to move motor 3 pad to motor 4 pad
resource mtor 3 A02
all seems to work!! 🙂
now if I could get that build of this version that would be great @lauka29 October, 2017 at 20:25 #39963
@mstan: good work! 🙂 I will include the changes to the beta 3 release.12 November, 2017 at 10:32 #40044
@mcstan: Did you have a typo in the
set tri_servo_feedback = EXT1? I guess that should be the RSSI? The Kakute doesn’t seem to have the EXT1 channel set.12 November, 2017 at 16:20 #40053
I did a spreadsheet when I was working it all out
so i knew what timing was on what channel
triflight was the beta 2
I can only guess EXT1 was the marked RSSI pad on the FC, my one was the all in one version
I did do the servo speed test and it seems to do it. IE did the crazy tail wag like a happy puppy 😛9 April, 2018 at 23:06 #57399lemarecParticipant
I Have a Holybro kakute F4 AIO V2,
Is this controller working with triflight and where did I set the servo ?
Thanks for any help9 April, 2018 at 23:17 #57400
I only had the version one… I did look at getting the version 2 but didn’t see a reason too yet.
you could try mapping it too UART 5?
I don’t know what the resource map looks like on Holybro kakute F4 AIO V2
