are you using (and have enabled) a compass/magnetometer? if not then there will always be a bit of yaw drift. if so, then i apologize and hope you get the answer you are looking for.

tovrin

1. if you disable 4 motors you will still be pulling their weight with the remaining 4 motors meaning you will likely be burning as much battery anyway. 2. if you are having issues with the throttle curve because of the added power you could try adjusting your curve in the GUI. 3. or you would likel...

tovrin

ok, so with the added header pins and spectrum plug soldered in place its another $5 (didnt include the gps, rgb ring or telemtry) which is still less then the onsale price of the crius at rctimer and this company is local to the states (if that means anything to anyone here)

tovrin

scrat is on target, first order of business would be to determine if vibration is causing your lack luster response. you can use the gui to see the vibration, use the LPF to see if this improves response (letting you knwo there is vibration thats now being ignored or reduced by the LPF) also, try fl...

tovrin

yes, i read that this morning off of hackaday, how fantastic!

tovrin

how does that compare to this?

http://witespyquad.gostorego.com/flight ... ption.html

seems very much the same and a touch cheaper, unless i am missing something.

tovrin

you would want to increase it it, but 1150 is pretty high already.
When you arm your motors, do they seem to be spinning pretty quickly? does your copter try to lift?

tovrin

this piece of code controls the speed that your motors spin at when idling. what was suggested is that this value might be too low and when its tilted and trying to compensate for wind a motor is shutting off. this code is near the top of config.h and can be changed to any # between 900-2000 but i w...

tovrin

for study purposes this should be what you want. its the basic schematic for all MWC

http://multiwii.googlecode.com/svn/trun ... iagram.png

tovrin

Code: Select all

#define MINTHROTTLE 1064

in config.h you can use this statement to adjust your min throttle settings. I think there is a good chance he is right, especially if you believe there is little vibrational issues.

tovrin

The FC is right out of the box...I didn't do any flash software mods or anything other than plug in the wires. i never trust these, who knows what version of multiwii is loaded, what sensor configurations are programmed, or anything. my opinion you should definitely load MWC v2.2 and configure it y...

tovrin

the APM2.5 has a magnetometer as part of its package, this will automatically eliminate yaw drift, there are many MW FC out there, and most all have different sensors, i dont know if your MW FC has a magnetometer on it, if it does, you need to enable MAG in the gui, and either tie it to a switch or ...

tovrin

start the motors with gui connected and check for vibrations on the gui.

tovrin

I'm going to guess you have a vibration issue somewhere and the wind is multiplying it.

tovrin

i agree with hayden, sounds like something is not setup right

tovrin

the spinning at 30% seems high, you might want to check your config.h for the following #define MINTHROTTLE 1064 it should be set JUST above where the motors start spinning so that do spin but at the lowest possible speed. you want them spinning for a couple reasons 1. so you know that you are armed...

tovrin

with no wind and level mode activated, does your copter hold position fairly well?

what version of the software are you running?

tovrin

yea, moped is right, grab the copter FIRMLY by hand, spin up the motors a little and move the bird lef/right/ up/down and you should hear the motors adjsuting, and if you have props on, should feel the resistance.

tovrin

Hamburger beat me to this one, start as basic as you can, disable, disconnect, and detach everything you dont need for basic flight. basically you only need the gyro for simple flight. if the problem still exists with only gyro enable i would guess you have a bad ESC draining too much power causing ...

tovrin

I've been watching this forum for most of 2 years now. Ive seen many versions come and get replaced since 1.8 when i started. Ive seen stability continue to climb and new features get implemented. The heavy forward momentum from last year has definitely slowed down, but commercially its a hit produc...

tovrin

you have a lot of I2C errors, in my experience that has always been bad solder on the i2c pins

tovrin

20 minutes on 2200mah? sincerly doubt it. i get about 8-10 on mine using 2200 on a 900gram copter. you need a lipo alarm buzzer, or to use the buzzer feature that MW uses. m is your fpv use the same battery as the copter? that will also drain the battery quicker. (i dont use fpv or gps) m this has b...

tovrin

acro mode is default mode when you are not in angle/horizon mode. it simply means the quad is only using the gyro, and not the acc. it will maintain whatever position you put it in until you change it to another. this is used for most flying applications. i fly almost exclusively in acro mode. angle...

tovrin

what you have <had> is a quad in acro mode, there is no recentering or level going on in acro mode. in the GUI you would assign a switch on your TX to turn on angle mode, which levels your copter when you let go of the sticks, do some forum searches for these terms and read up while waiting for your...

tovrin

aimatt, i am late on this post, did you ever order the boards, how can i buy one from you?

tovrin

its really hard to tell in video due to frame rate limitations but the motor that is not lifting looks like its not spinning fast enough. i am going to guess that the ESC calibration has nto been done, like what Scrat said. its a very dangerous tool if you dont use safety precautions, TAKE OFF ALL P...

tovrin

your picture didnt work. With the LEVEL while holding the position, but the wind is still leaning in the direction of the wind. Furthermore, if I want to go faster, so the copter leans in the direction of flight and can not be compared, so I copter crash I'm not sure i understand this, please try to...

tovrin

i dont run an H quad, but i do run a custom built X quad with 850kv motors, 12x4.5 props, and a 2200mah battery, i get about 9 minutes. Your hover is at 45% yet things are getting hot doesnt sound like a weight issue, so this makes me wonder if there is another problem, likely related to your YAW is...

tovrin

Hamburger, to extend the range in the ESC i would have to reflash the ESC with range altered simonk firmware, correct?

tovrin

put some 20a simonk flashed generic ESC's http://witespyquad.gostorego.com/speed-controllers/ready-to-fly-simonk-house-esc-20-amp.html on my quad, it had been sitting for awhile due to a single aeolian ESC flaking out. the first thing i noticed, was the quad was MUCH quieter in flight. the second th...

tovrin

i keep my YAW rate at .70 and it turns my bird pretty quickly without any control issues.

tovrin

i am not certain, but i believe thats for powering the TX via power brick, i dont think its meant to charge the batteries.

tovrin

thank you Lenz and Scrat, i was thinking that was what i was doing wrong, i have to wait till this weekend as i broke a boom trying again on sunday, and i will play again. I am also curious if my motor speed is to partially blame as well, im running 850kv motors. i have a smaller quad, presently wai...

these guys have some decent ones too, from $18-$125 depending on options, but their $40 one seems near identical to the one you bought. they are easy for me since they are in Florida, like me! overnight delivery is the best!

tovrin

nothing i do seems to stop my quad from crashing when i flip. i keep going higher in the air and it keeps making bigger circles, it always finishes the flip so it is right side up when it hits the ground but it hit so hard today that it ripped my battery strap in half and slung my battery out of the...

tovrin

is it a fast wobble or a slow wobble? im not an expert by far, but this sounds like a PID problem.

tovrin

i would love to see a comparison, thats frigging awesome.

tovrin

+1 to patrick, always a great help!

tovrin

update: i finally grew a pair and gave it a shot, my first attempt was slightly too low and the copter flipped completely yet hit the ground pretty hard right side up, thankfully my tie strap landing gear absorbed the blow. my second attempt was worse, though i swore i was higher in the air, lol. 2 ...

tovrin

give a screenshot of your GUI when connected.

tovrin

as peter said above, this is the wrong place for this post, please post in the connecting elements forum and someone will answer you directly.

tovrin

it sounds to me like your ESC control cables arent set right. when i first got my flip board i plugged my ESCs into it wrong, i had flipped the plug over so that the control wire (white) was in the ground slot and ground (black) was in the control slot. power (red) is in the middle so it was always ...

tovrin

ok, my charger only has capacity, but it uses that to determine current. for instance i set my 2.2mah battery up as 4.4mah when i want it charged at 2C, and i set it at 2.2 when i want it to charge at 1C, etc.

tovrin

I'm confused by this because i have had no problems, my TX is really cheap and sloppy i not only have to set a deadband but i had to lower my max and raise my min as such // ****************** // rc functions // ****************** #define MINCHECK 1175 #define MAXCHECK 1840 this is done in the multi...

thats a really good price

a quick google of the title of this thread pulled up the following...

yea, theres something to do with TX library for x64 that doesnt work. I have much the same problem, i can run the x32 app perfectly if i do it immediately after rebooting, but once i close the GUI i have to reboot before it will work proper again. timecop, i think, has said that it works perfectly o...

tovrin

what operating system are you running? Ive had a lot of issues getting it to run on 64 bit anything.

tovrin

personally i think that the video posted early in this thread is one of the best PID teaching tools there is. it doesnt get explained any better and its visually informative.

tovrin

thank you scrat, i was adjusting my stick rate last night in preparation for this, and .5 seemed best, i had it up to .65 and it was too twitchy for my skill level, i was using .35
