So I'm new to the forum so first off i want to say hello to everyone and thank´s for many hours of reading and many solved issues along the way.
And the greatest of thank you to Flitetest for making all this happen!
I have been tinkering away up here in Sweden during the long and dark winter building a DW Tricopter 2.6HV Deluxe
But finally summer have come and it´s time for FPV.
This is my first FPV platform and i have to say it feels like i had the fortune of instant success. Im a lousy LOS pilot but flying FPV just feels much more natural.
My build is basically the same as Davids from his Rcexplorer.se site with the exemption that I'm running multiwii
Flip2.5 from RTFQuads.
To say the least starting with Multiwii and having no experience in FC´s was quite bite of info to swallow.
Thankfully there is a ton of info around if you just take your time to find it.
There was one big obstacle along the way.
Jittering tail servo.
I bought what i thought was a better quality Turnigy servo Hispeed MG digital and I'm shure it´s great but mabe not for tricopters or multiwii. I played with gyro filters and servo filters in the MW sketch but with little result, moving average gyros seams to help but not totally. In the end i changed to a slower MG digital servo the Bluebird servo David recommends in the FT tricopter build video combined with moving average gyro in the sketch and behold the jittering went away.
I would still want to use a real good servo even if it cost a´lot just to be shure it will hold.
If anyone have a recommendation for a good quality servo please tell.
Then there is a few things i would recommend if starting out with multiwii
#1 Get the bluetooth, makes it easy to adjust PID and other settings.
#2 Run MW V2.3 and be sure to run the latest MVconf or you might have some bugs.
#3 Calibrate you're speedcontrollers and always run Simonk
#4 Don't be afraid to experiment with the sketch you can just upload a new if you mess up.
#5 Get a CNC cutter and CAD and a lasercutter and a watercutter and a 100 other fun stuff to cut your frame and other bits and pieces in stead of doing like me and cutting G10 and Carbonfiber by hand
#6 Don't use the barometer until you know how it works ( i smacked in to the ground on deecel l and gave my self 2 more days work)
Now there is a few things i can't figure out and therefore i turn to you guys and gils here.
I have some kind of glitch in my tail servo it is not consistent and only comes now and then.
There is no jitter but from time to time while flying or on the ground the servo goes full left and full right in a micro second and then everything is normal until it happens again. This is really annoying and i can't figure it out.
You can see it in the video at 0,34 and 6,34
I have a vibration issue in my camera tray in high speed that i think is either the 1mm carbon plate or to soft metal in the vibration absorbers.
Would you mind looking at the linked video and telling me what you think about the long distance focus on the Gopro hero3+ Black. Some people are saying you have to refocus the lens. Is this true for all go pro´s of that model or just the early ones. I don´t know how much better it could be but i may be blind.
Here is some pictures of the Tricopter
The tail mechanism is from Armattan and is really strong and solid
I include my PID´s, they are by no means perfect but they work, I'm still trying to get them tweak´d out.
Again Thank´s to all the great people here on this site.
