...About last copterposition, there is far small memory for continous recording the flight. If you have a signal loss, it can be the trigger but what is the guarantee of having signal back at that point? I think the home is the most relevant target in Failsafe because when copter is closer and clos...

I know PID's in MW2.2 are 33/40 of earlier ones. Normally I start at the Standard-PIDS and increase P step by step until the Kopter starts to wobble. My experience on different Kopters is: The Kopter doesnt wobble even on very high P-Values but in Flight sometimes suddenly comes an unexpected Roll.....

first of all: congratiulations, this mod is great, many good ideas, and they are working, very good work. Safety for the Copter in mind, I have two Ideas: 1) Loosing RC-Connection is in most of the cases a question of the Copterposition. When the Copterposition is recorded during flight with good RC...

good for different payloads (Akku, Camera...)

another Wish / suggestion:
keep track of GPS-Pos if RC-Signal is good, set this as CH-Pos in Case of loss of RC-Signal (Failsave) and activate CH to back RC-Signal

another Idea / Wish:
optional Autodetect when fail of one ESC/Motor/Prop (measuring yaw) and switch Motormix for rescue-flight (possible of course only with 6 or 8 Motors) e.g. switch hex2quad

Hello mistahead,

I tryed every 10 Steps from 920 to 1000. Tx is trimmed from 998 to 2011, calibrated Esc's with this ( when not calibrating with MWCode)

Hello, I had an frustrating Weekend with NanoWii. I tryed so many MINCOMMAND and Minthrottle-Combinations, powered the Board from ESC and tryed from (even seperate) Lipo, first powering FC then ESC'S and the other way round.... always the same: unreproduceable sometimes ESC arm, mostly not. My setup...

It's just an Idea - but we are in "Ideas" right I recognice in the GUI, that the Sensorreaktions have slightly different Timings. e.g. the value from the gyro hasn't reached it's max but acc has already it's max-Value. Gyro should have it's max at about hlaf the way acc, so there is an tim...

Did you calibrate your ACC?
In one Video it looks like Copter wants to get always the same ´Position every time you put throttle on it and so ACC gets active. Best you recalbrate ACC with stickkombination, Copter standing on the Landinggear.

As I understand it is possible to a) connect the defined outputpin to an HF-TX or b) connect to trainerport i'm afraid this works with TX with selecable channels for Trainer only (?) I know there are PPM-Injectors extending channels e.g of Futaba 6EX, injecting HT-Signal on Channel 7+8 (behind the c...

I had to install a new ESC because the old one smoked (got wet). I tryed to calibrate it connected to rx throttle, throttle high when connecting the lipo, waiting for beep, thottle low, waiting for beep, motor was running and working (connected to rx). Connected to FC it didnt arm. I set MINCOMMAND ...

I own an Futaba 6EX Tx and I am satisfied with it, but... - I need more Channels (Headtracker) - I would like to share my flyingexperiences with friends, giving them the chance to fly as student with the second Tx So I like to get an second Futaba 6EX to manage both. Futaba FASST-Technology should g...

So a new, undiskussed Fact is: hoovering in stablemode near MINCHECK is very dangerous, much more than in acromode. But stablemode is not only for Beginers but also to get more security taking Fotos or for FPV... so very bad "behavior" in my Opinion. There is a Difference with ACC aktivat...

I had the same experience.
Against the things I read it is not enough to calibrate ACC in GUI, you have to calibrate it with RC-Sticks. Thereafter the Trimming can be done.

have a Look at http://www.multiwii.com/forum/viewtopic.php?f=18&t=1401. The last Post on the first Page is the way to solve this Problem easy

same experience by me with different setup: Suppo2212/13, Suppo 25A ESC, MiniWII, 1045 or 845 Prob. 1.rst I learned, that Trimming for stable only works, if calibrating is done bevore WITH RC (Gui-Calibrating was not enough) 2.nd same as decribe above: stablemode is not very stable, different every ...

a few weeks and many flights later I recognise following: The Problem ist, that the copter flips, when throttle ist lower than MINCHECK. A few Weeks ago (Posts above) it was a big Problem for me, because I was flying stablemode and very slowly. Now my prefered mode is acro, there are many more Stini...

I know - the Answer is the last Post on the previous page... easy and brilliant. you can check in the gui of mwc how much trimming your tx needs....

OK, nobody seems to have experience with this, so at least I tell what I found for others suching this Forum, that Rhosewhite has MINTHROTTLE at 1150 @ most of his Copters.

Of course you have to check yourself that Motors are running stable with this.

OK, back again with the next Question: I want to set MINTHROTTLE as low as possible because sensorcorrections are driving my Copter up during hoover. The MINTHROTTLE is defined somewhere at the Beginning of config.h, it's commented as ESC-related. Now I have to try out, what my ESC's need as a Minim...

Oh my God... what a simple Solution... seem's I'm not only a bad Programmer

Thank you for this Idea, I'll do it like this.

Thank you for your Tipps, it seems to get more complicated then I thought. I agree with you, that there are safety Reasons to look at, I don't want to loose my Copter to the Sky because shaky Wind is causing Corrections whitch let the Copter go up and up and up... So there should (or has to be) a Po...

we set error angle to 0 (ie : no correction) only if your are not armed and not in safe fail mode .. thats should do the trick I don't understand: Why do you want no correction in failsafemode? the copters may have difficulties to lose altitude .. ?? I don't understand this. Reason for the Codechan...

When I want to change the code to get a stable sinking during throttlestick at minimum when in stablemode, I guess the following should work: Original: if (rcData[THROTTLE] < MINCHECK) { errorGyroI[ROLL] = 0; errorGyroI[PITCH] = 0; errorGyroI[YAW] = 0; errorAngleI[ROLL] = 0; errorAngleI[PITCH] = 0; ...

stable sinking flight
corrections thru sensors while Thottle at minimum, switchable flexible like e.g. sensors in GUI

Thank you for the explanation. Unfortunately or me the Code is not so selfexplaning (because I'm not an too good programmer), but I will have a look at the code and try to change it, I think about something like: "In stablemode correktion is on during low throttle". When I made my changes ...

Hello I'm Newbee and I try to understand the working of the parameters. Thats what I understood til now: MINTHROTTLE: given to esc's when throttlestick is at minimum (without correcting influence from arduino). MINCOMMAND: given to esc'c when armed, minimum value given from arduino to esc's. MAXTHRO...

does the Arduino only give the throttlevalues to the esc's or is there a feedback from the esc about the real rpm to the arduino? Are the values shown in MWConfig the values given from the arduino to the esc or the real rpm? As Consequence of this my concrete question: i found 1 of my 4 motors to gi...
