Hi all, I finally just made the test by myself and it's working perfectly at MINTHROTTLE 1150 for my 4 Turnigy PLUSH 18 Amps ESCs. For people that expected that they do not work, they're out, they work great ! I'll test this settings for Turnigy PLUSH 12 Amps ESCs as well and post back for the resul...

Hi all, hope everybody is fine here with his multis I recently setup a new quad with a SK450 frame from HK which is great stuff, added some KDA 20-26M motors running 8x4.5' props. But reading through the conf file (config.h) I'm used to the Turningy PLUSH 10 Amps ESC, and there's a specific MINTHROT...

Hi, I'm not having this exact type of board but flying with a 328P and MPU6050 witho0ut anything else through the I2C bus. Last time I had a strange behaviour like yours was the day my ITG3200 fried on the board while flying As it seems that you've got an all integrated card it'll be a little tricky...

Salut Olivier, ça roule ? For this kind of issue, I'm also using a 10DOF from Drotek without any problem. I had fried an ITG3200 on a Drotek 6DOF V2 last week, gyro was not working anymore, it was still addressable through the I2C bus, but no data were sent back from the sensor to the MCU Have you t...

@tovrin, you're completely right, I haven't seen that deprys' center values are offset. Those should be set to 1500 using SUBTRIM on the TX first, and then adjust END POINTS to around 120% (Futaba for instance), then you'll have a complete ~1000 to ~2000 range of values with a perfect center at ~150...

Hi all, I finally found my issue concerning motors that are moving asymmetrically, in fact I have my ITG3200 fried on the IMU It responds to its I2C address (0x69) but gives back absolutely no data, everything is well defined in the config.h file. If you face something similar, the behaviour is almo...

Hi, @Derpy: have you found something to solve this issue ? I have almost the same behaviour but my copter is flyable for the first 5 minutes, then even if gyros gets recalibrated (PITCH stick back and YAW stick left on the ground), it flips when I take off immediately. Does anybody know about that b...

Hi guys, Hamburger, I think , like you, that the frame design doesn't matter at all in that configuration, because you have 4 motros so it's by definition a "quad". What's important is if the flight controller board is perfectly in the center of the circle made by the 4 motors, so if you p...

Hello,

I also use something I made like the one from Undcon:

http://www.undcon.com/2012/05/05/esc-ca ... -and-dymo/

Works perfectly well

, be just careful not to wire the positive wire to all positives pin on all ESCs, just one between the receiver and one ESC is fine.

Nice job ! Concerning the manual, I also spotted two small typos: ⋅ in the header of the page: "Chose" (should be "Choose") ⋅ In the Power source connection page (4/13): "ATTANTION" (should be "ATTENTION" or "WARNING") Laurent

Thank you !

Yes, I know

but that was just for being "mind free" as I want things done correctly

The mega isn't fried because it's working perfectly under 5V through VCC

Hi all, I had a bad experience with one of my promini board (wrong power voltage applied to it ) and as a result I have fried the SMD capacitor C19 just before the voltage regulator (RAW pin). The reference of the component is "106", so it's a polarised unit (rated at max 25V as we should ...

Hi all, thanks for the excellent work done concerning the OLED display integration to the multiwii project, so far so good A simple question regarding the electrical connections of the display: 1) how about connecting it directly to an BEC output of an ESC (around 5.2V) is it OK or not ? 2) concerni...

mon_lolo_fr

Just to say that I personnaly prefer QuadX, for the look , they're funny to fly ! For camera mounting purposes, I prefer a tricopter (or Y3/6) because of the angle of view you can exploit in the front of the copter (remember that a GoPro cam could be setup to achieve a 170° of field of view !), so i...

Hello,

I fly with prop savers mounted on 4 Turnigy 2204-14 motors, that's working great but as you mentionned there's a little difference between a hard connector (prop adaptor) and prop savers, test them both to see that difference.

Laurent

Yes, thanks Alex !

It seems that they're not in sync on their documentation because, on the following datasheet http://www.ohararp.com/files/FMP04-TLP_DataSheet.pdf page 8, the pin 5 seems to be usable ! And on this one http://www.ohararp.com/files/FMP04_DataSheet_R02.pdf , it seems not ! Sorry for my post on the poss...

Hi, have you checked on pin 5 of the FM04 GPS board, if you have a continuously output one-second high-level with one-second low-level signal ? This means that you'll have at least 2D fix, afterward pin 5 will be continiously at a high level when 3D fix is OK. After that, check to see if you get pin...

@EOSBandi: this is impressive, as I just read your code, I'm impressed, really.

I'm wondering if you're working as a developper or in an IT team. Unfortunately I'm not skilly enough to well understand your code (OK, more or less, but not in deep !).

Nice work indeed ! Who test ?

mon_lolo_fr

Hi all, nice project in scope I'll be interested in helping to realize that thing. My thoughts are the following: - the I2C slave (328p + serial GPS on RX0) would simply "publish" (meaning making GPS data available) like a buffer to the I2C master (main 328p that control the copter) - if d...

Hi all, hope everybody is going fine with MW copters I just designed a frame for a QuadX (4 motors), with an camera support intented to be used for Gopro/FPV or something like this to be mounted on the frame. It's a little like Paul's Flyduspider, but with only 4 legs, my view is that it'll limit th...

Hello,

same issue than you trying to compile a v1.9 on arduino 1.0

Turnigy PLUSH 10 are operating in linear mode (as in the HK documentation !)

Did you find what it was causing you the problem. As I'm having the same problem, if you don't know what caulsed it imwas wondering if you would you be able to forward on the sketch If you see the green led still solid, it could be that the sensors are not readable by the MCU, clearly a WMP/IMU not...

The ESC controling the rear right motor is connected to pin 9 of the arduino, it must rotate clockwise with a clockwise prop. On the vid, your prop is OK on the rear right motor but the motor is spinning the wrong way. Swap 2 of 3 wires that comes from the ESC and go the to motor, you'll then be abl...

I also examined it and conclude the same, seems that the rear right prop is spinning the wrong way !

mon_lolo_fr

Absolutely, I mean checking each "power unit" independantly in order to determine if it's the CPU board that does not allow the motor to pull up to full throttle. Check that in two steps: -> first directly from your receiver to the ESC witn a linear throttle curve and check if the thrust i...

mon_lolo_fr

You could try to connect only one motor and its ESC at a time, and try to handle it by hand (be careful !), push the throttle until you feel a good lift from this motor side.
Do this one by one for the 4 motor and ESC, I think you have contradictions in the corrections in the vid.

The WMP has its own onboard voltage regulator, why moving VCC to 3.3V ?

I read an obscure post about needing to disconnect the FTDI 5V pin to get readings from the sensors... I have just slapped together a special cable that allows me to switch the 5V line off and on; this did not improve the problem.

Hi, this is a good question Franck. Mine is the following: could Alex or somebody experienced with MWII could give us a range of "good" and "bad" cycle time for the 1.9 version ? Something like: 1) for WMP only I2C device connected onboard good: 3500 to 7000 bad: <3500 or >7000 2...

mon_lolo_fr

The I2C errors are a problem that needs to be fixed. I would start the troubleshooting by gently tugging, pulling, and tapping all the electrical parts and wires (while you watched the debug2 data). Hopefully you learn something from that exercise. I agree with that, it'll be a good exercise to fin...

Everybody will have the same variations around centers of the sticks, with any radios, that clearly reflects the sticks' potentiometers behaviour.

No analog potentiometer returns exactly in the same position once it's been moved !

mon_lolo_fr

Hi, for Futaba radios, you should set MIDRC to 1520, that's Futaba's default center. The other solution is to use your radio subtrims to move the center of the sticks back to 1500 in the radio (around -20 steps in a 8FG for instance), you can do this setting by checking throughout the GUI, then you'...
