hey, you may trim all axis using your transmitter, but i suggest you to do in acro mode. Afterwards switch to levelmode and eliminate drift in this mode by landing and doing the stick input method for "Trim ACC" as descirbed here -> http://multiwii.googlecode.com/svn/branches/Hamburger/Mul...

Hey, i did encounter some error while flying fpv. Adding some additional asymetric weight, seemed to lead to the problem (fpv transmitter+osd). For analysis -> http://www.quadrocopter.at/vids/fpv-shikra-lvl-fail.mp4 holy tree batman! Around 4 Minutes inflight it started pitching forward/left very h...

Anyone using the MiniWii-Board from Jussi? I had to change the Sensor-Orientations for the actual MW 2.0 to the following: #define ACC_ORIENTATION(X, Y, Z) {accADC[ROLL] = -X; accADC[PITCH] = -Y; accADC[YAW] = -Z;} was: #define ACC_ORIENTATION(X, Y, Z) {accADC[ROLL] = X; accADC[PITCH] = -Y; accADC[...

Solved a big mystery. Replacing the WMP+ with a ITG3200-breakoutboard(defualt lpf set), did the trick. No accumulative drift in acro or level mode(BMA180). Everything working fine, tested both sensors with mw2.0pre2 (wmp+ still caused a drift). greetz Noc btw. never touch your mag with a soldering i...

Noctaro

hey, wich sensors are active? A yaw drift may be trimmed out with your transmitter trims. Increasing I would lead to a stronger levellock and may help also. Activate the deadband option in config.h if your transmitter potis cause jumps in gui. Try to add some expo in gui for smoother inputs. Note th...

Noctaro

Hey,
sounds nice! Wich version of multiwii did you use for your mods? I would like to give it a try. May you upload a moded archive of the firmware you used? Thanks for sharing your idea

greetz Noc

Noctaro

is it the same behaviour if motor is disconnected? if so i would tip on some strange mixing of your rc or fc.

Hey, last days there was a lot of wind outside. As my copter does not like storms, i thought of building something that may use the airflow for gaining height. I got a low budget, so i decided to create some depron wing. There are great plans available at http://www.mikeysrc.com/FPV_V3.html if you p...

Noctaro

hey, i did test lastest svn release of dev20120225, altitude hold works quite nice! Stable within 50cm also outdoors (not to much wind) Also drift in stable mode is quite controllable. Using standart PID and activated ITG600/BMA180/BMP085 greetz Noc edit: with additional weight of the gopro i guess ...

hey, yes, the anti-vib mount performs really nice. Could not believe myself before i tested it. I will add some footage with balanced props shortly. Will try to do some FPV flight using your mod. (Safe area of course) Xenon 2 was one of my first pc games and i loved it! Maybe thats why it sounds a b...

Noctaro

Hey, I recalibrated MAG and have done around 5 successfull flights for now. Its definatly worth giving a try! btw. cycle time around 3500-4800ms using BMA180/IDG600/HMC5883/BMP085@100khz files here - test carefully.... Also includes CRIUS defines (I don't have one - provided by a friend) http://www....

Noctaro

Ok, thanks for the info!
The drift that occurs at my quad, seems to be temperature undepended as it will also constanty drift(over time) if acclimated . Thats why i did hope that its depended to the vector misbehaviour.
But i will give it a try, just to see what it does

greetz Noc

Noctaro

Hey, shikra! I do not know exactly what you did, but however my quad is behaving very close to perfect with your new release! Descending down very gently, nearly no wobbles. Stable in groundeffect. And its quite easy to fly now! I will post some video footage using this mod! Btw. i did no PID tuning...

Noctaro

May this also kill the level drift over time that occurs on my quad? As it feels as some variables (pitch and roll) do constantly drift off over time. Could this be related to the vector misbehaviour? (ITG600 [orig. WMP+], BMA180, BMP055, HMC5883l ) Wich version of multiwii do you use for this mod, ...

Noctaro

Never ever move your quad after connecting power! You are disturbing the gyro init routine! Your quad hangs on a rope and swings as connected to power you got to let it initalise/calibrate at some flat unmoved surface! (Not touch it around 10 secounds after power connect until led stops blinking) gr...

hey,
i tried wingui on ubuntu using wine 1.2, but as for now i am stuck at installing the .net client. Had not too much time to test, but i will have a look if i can find some nice installation routine.

hey, also worked for me, just didnt upload it right now. Are you using Arduino 022, 023 or 1.0? greetz noc edit: uploaded and done some offair testings, and a short air test (of course it started to snow as i went out) but for now i would say it performs really good. Nice smooth return to level with...

hey, dev version means development version, wich may contain bugs or is at testing stage for new implementations. 1.9 was a stable release as it worked fine for most pilots. Of course development versions may offer new features, so its your decision wich version you gonna use. You may download dev V...

Noctaro

Hey,
as far as i know, we need to do this to compensate the vibrations. It seems, that some pilots including me had a better flight experience as resolution was lowered.
Don´t know too much about the programming aspect of this.

greetz Noc

Noctaro

Hey, i have tested also indoors(acclimated) now, but was not able to do a safe flight. Holding my copter in hands, switching on baro leads to a critical power reducing. Even if i alter height about ~1,50m there is no reaction from motors. Btw. i am using the PID you suggested to start. By Temp drift...

Hey, if you are like me continously testing new frame designs, you maybe would like to test this centerplate template for a QuadX i created using Qcad. Most of my frames are based on wood centerplates. I like to print out a template, glue it on some woodplate (i use 3mm layered wood) and have a nice...

Noctaro

Hey,
tested your new release. Disconnect routine is working fine! Thank you for implementing!
Btw. would it not be nice to have a "check/uncheck all" button for realtime graphs? (Sorry if anyone already mentioned)
greetz Noc

Noctaro

hey, i did test your new gui with yesterdays svn release and i am very happy to say,so far i have tested it everything is working as it should! Great Job! greetz Noc edit: There is one thing i thought of. I have to disconnect quad for doing mag calibration dance and forgot to press the pause button....

Noctaro

hey, thanks for reply, i tested your mod with yesterdays svn release, and everything seems to work as it should. As holding my copter in my hands i can watch some strange wobbles around level position and some motorpower reduces ((P=9) (I=0.45) (D=70)). But it finds back to level. Stick input is als...

Noctaro

hey, edit: i tested your release MultiWii_dev_20111220_Magnetron_Marbalon.rar, acc/gyro smoothing seems to work fine. Had a nice stable flight. Also seems that the temperature/time drift that occurs on my quad, was a bit more controlable. Baro did not do the trick, but its around 0°C outside. (GUI i...

Noctaro

hey, @shikra: i added the up to date code to your archive release and things seem to work better now. But there is one thing thats a bit of confusing. If i hold my copter at the backside and pitch it back(using my hand) in levelmode, the recoverypower seems very limited. Maybe my too low level P(10)...

Noctaro

Hey all, i will recheck the code i have used. I think you are right shikra, i just downloaded the one you posted on your server (archive), if it was not updated i got the error from here. I will have a look for it in the code now. My wiring seems just fine, i reconnected everything had a look at my ...

I will again uplad a short takeout. I am pretty sure there was no snowflake at my esc. I do not know whats wrong, but for t...

Noctaro

I already thought about this happening, and i would lie if i´d say it can not happen. Everthing seems to work again, i will do another testflight much higher, to have some reaction time and to ensure that no snow will be blown up to escs. Right now its snowing too much to do an safe testflight. gree...

hey i just wanted to share some nice way to get rid of tearing and other vibs in your video footage this is made out of 2 sheets of balsa, glued together using ~4mm ohropax slices. keep in mind to not fix the plate holding your cam, it should only be held by the ohropax as a screw would transfer vib...

hey, nice captures, but the watermark does really destroy the impression. maybe reduce its transparency a bit?

as far as i know its strongly recommended to kill the 5v plug of your ftdi to not overboost your sensors. but as matbogdan mentioned, it may be depending to your hardware.
