6S Tri-Baby build (Matek F405-AIO)

[Kevin_Erik]

Impossible Tail-Mech arrived!

So far everything looks good but i am waiting for my servos to arrive.

[Kevin_Erik]

The Impossible Tail-Mech has been installed and flown with 6S today. Maxed out around 46 Amps per motor or 91% of full throttle before the limiter kicked in to save the ESC’s.

Edit: BlackBox Log file was too big to upload to the forums so i’ve added it to Google Drive: https://drive.google.com/file/d/1KLJjNwpeJDezMr_f3tjsPdD9Pq38SNEt/view?usp=sharing

Flew it pretty damn hard such that I had screws that had backed out of the motor mounts!

These look like nice motors for the Baby: https://www.getfpv.com/tmotor-f60-pro-ii-1750kv.html?

[LitterBug]

F40 pro II would be more than enough for the baby tri. Not sure going to F60 would gain much. The F40 ProII are capable of 1800g thrust each. I’ve got Edge R2205 2480kv on one baby, and Cobra 2207 2450kv on the other. Those are more than enough for a baby tri. The Edge are crazy light and responsive. I’ve had to detune it quite a bit to keep it from oscillation on all axis. I’m actually thinking of updating my first Mini tri from F40 2300kv motors to a set of F40 Pro II 1600kv. Have a set of those on a 5″ quad build, and it rips bawls. If I wasn’t already working an F80 mini build, I might consider turning mini 1 into an F60 build, But Really gotta have at least one “tame” build. LOL

I think I’ve almost all traces of Tail-wag gone! Just had a flight that was excellent with only minor snap back after turns. Even prop wash was muted compared to before. Seams as if the Yaw Terms, specifically the “P” has to be very high for it to be effective. Thus far I’m at 170 from 105 previously.

Note: Will post a video soon.

Loctite blue on the the motor mounts, And make sure you are engaging the “ny” on your nylock prop nuts. Stuff shouldn’t be falling off. 😛

Cheers!

@LB

I recall being told off the other day for no reason other than replying to you.

[LitterBug]

–<< I must Fly more >>–

Shutting up and flying ….

[Kevin_Erik]

Well as your so fond of context….

I refered to you as a “Sourpus” simply because your taking things too seriously with your grouchy disposition. You should lighten-up when something irritates you rather than lashing out. Beyond that, if you prefer we can simply agree to not reply to each others threads. Sounds childish but hey if that’s what it takes then by all means.

Edit: Here’s an idea… Lets just drop this and both stop acting like retards.

[lauka]

@Kevin_Erik: that starts to look good. You could try increasing the Yaw D term, it is not doing much at the moment.

I will do some flight testing myself soon.

[Kevin_Erik]

@Lauka Any thoughts on how much “D” to add? Also be aware that my non-standard configuration may not be the same as your Tri.

[LitterBug]

I have a better idea. Next time you think my panties are in a bunch, Just tell me to shut up and fly! I obviously haven’t been flying enough.

Cheers!
LitterBug

Edit: PS. Got a few packs in last night and already starting to feel better! 😀

[Kevin_Erik]

Video or it didnt happen!

[Kevin_Erik]

Today while adjusting my Telemetry I noticed that my Gyro is not longer detected nor can i calibrate the accelerometer! WTF, i just installed this damn FC last week!
