Why do we need a hardware converter for frsky telemetry on a multiwii, when cleanflight/naze32 seems to do it with no additional hardware? Does it have something to do with the "old" telemetry used in the D4R/D8R vs new in the X series? Id be happy with support for the old ones without nee...

hello, i am new to cleanflight, and did put the filmware yesterday on my naze32 acro board. tonight i did try to do autotune with the standard pid settings to start with. so i put it in angle and in hoover. then directly he do a few roll movements, and my quadx drops out the sky. is this autotune s...

I was playing with the RSSI_ADC feature (using D4R-II, RSSI connected to chan 2), and Im afraid its all but useless. The values dance between 95 and 100% when actual RSSI is between 60 and 100+db. If RSSI drops further, the values begin to swing rapidly and enormously from like 60 to 100%. Even afte...

Edit: someone on rcgroups pointed me in the right direction by linking this document: m Perhaps its a good idea to link or refer to it in the document explaining serial ports. Below for reference my original post, but I can probably work it out now. Im confused about the serial port settings. Ive re...

Vertigo

Decided to try the autotune feature. It seems to work, but there is one thing I dont quite understand. Im using an acro naze, and Im not sure how the quad is attempting to maintain its altitude. Its climbing during the tuning and since I was doing this line of sight, I quickly risked it getting too ...

Vertigo

Acro mode. But I seem to have solved it. Cleanflight + 5x4 props + increased I factor on pitch seems to have cured it. Probably the I factor mostly.

Vertigo

As it turns out, my gyro's are fine. I did another testflight today, with different firmware (cleanflight), different props (5x4 instead of 5x3) and higher Integral values for pitch. And the result was a near flawless quad. Ive not yet determined which of those factors contributed most, but I do not...

Vertigo

small update; the quad with the new/old acro only controller and cleanflight flew absolutely perfectly with stock settings until I crashed in to a sign board . UNfortunately, I destroyed a motor, so now I cant test if it works with baseflight too, thereby identifying either the board or the firmware...

Vertigo

Im looking at the raw sensor data tab right now. The X axis is showing a steady 0. The Y axis (which responds to pitch on my quad), is alternating quickly between -0.24 and 0. The Z axis is a steady -0.24. Does that sound about normal? 0.24 degree per second doesnt sound like it would cause problems...

Vertigo

DO you guys figure its possible to damage, without destroying, the gyro's in a crash? I already explained I had one quad that would violently overcorrect in acro mode. that seems to have been solved by installing another naze controller and another firmware, havent yet figured out which of both actu...

Vertigo

I just installed cleanflight on a spare naze board in an attempt to cure the overcorrection problem I was suffering with the other board + baseflight in acro mode. Ive only done a short test flight in my garden with stock settings, so I will try not to jump to conclusions, but its never flown better...

Vertigo

swapped out the board for an older naze32 controller (one without baro) and installed cleanflight firmware, and though it was a short test flight in my garden, even with default settings, its never flown better. Cant say for sure if the problem has been cured yet, but If thats confirmed on some long...

Vertigo

Care to post another dump of your current settings?

Vertigo

Is there an (idiot) guide to downloading, installing and configuring harakiri?

Vertigo

New frame, new motors, defaulted all settings, same problem. Angle and horizon work fine (aside from horizon occasionally leveling inverted it seems), in acro mode, I get the violent overcorrections. Time to try another firmware I guess.

Vertigo

I even did a full chip erase since I was experimenting with other firmwares. then reimported my dump. All the settings are where I want them, nothing weird there.

Vertigo

Subscribing here, as this is exactly the same problem I reported here yesterday: http://www.multiwii.com/forum/viewtopic.php?f=23&t=1947&start=950#p55907 IT also appears identical to the issue reported here: http://www.multiwii.com/forum/viewtopic.php?p=53330#p53330 and here: http://www.mult...

I dont have a vibration problem. My problem appears identical to what Thorvald reported here: http://www.multiwii.com/forum/viewtopic.php?p=53330#p53330 and antix here: http://www.multiwii.com/forum/viewtopic.php?f=23&t=1947&start=900#p53402 The only difference is that upgrading the firmwar...

Vertigo

acro mode is gyro only. Thats what you'd think; but for instance if you enable throttle angle correction, then it no longer is; then even in acro mode the acc is being used. I had that enabled initially, and figured that might be the source of the problem, but disabling it doesnt seem to cure the p...

Vertigo

I have been having a slightly annoying control problem, and after posting this in an rcgroups thread it seems Im not alone. THis happens in acro mode, when inclined at a forward angle and centering the stick or applying a little back elevator to reduce the flight angle, the quad will often violently...

Vertigo

I tried this out yesterday, with mixed results. I tried the FPV settings (+40 / 450). It does work well if you fly at reasonable angles, but if you approach (possibly exceed) 90 degree angles, something is wrong. A few times I was at such very steep angle in acro mode, I wanted to bring the nose bac...

. MTK 3329 (with different firmwares) is tested for basic function and works in NMEA and both binary formats however ublox is recommended. Do you need to configure what port it is connected to (serial/softserial/.. ?) Or otherwise activate GPS somehow ? My MTK is soldered to channels 3 and 4 (defau...

In Harakiri in althold/baromode the throttlestick becomes just a stick that gives your wishes to the FC I wasnt talking about althold mode; I do want manual throttle control, and its okay -even desirable- that with a full battery hover is achieved with, say 30% throttle, and with an empty battery a...

Vertigo

Thank you very much for a very elaborate explanation! Failsafe sounds pretty sensible, however the way it works, it sounds as if I should disable the FS function of my receiver, so the flight controller understands its a FS situation and not a manually triggered RTL as it seems to react slightly dif...

Vertigo

Open a normal serial connection to the FC and type 3x Enter or ### (3x "#") Thanks, that seems to work. One more question (for now); what does harakiri do when a valid home position is registered, but the GPS reception is lost during the flight and then a failsafe RTL is triggered ? Im fl...

Vertigo

Im slightly confused. I want to try harakiri, I managed to flash it to a naze test board using baseflight (flashed the .bin). But I dont understand how to configure the "cli" options. I cant connect using baseflight, and I can communicate with the board using MultiwiiConf, but there is no ...

Feature request. Would love to see Cleanflight implement mixers like OpenAeroVTOL for KK boards. The idea is that you could use the board for hybrid VTOL craft, and transition between hoover and forward flight. In my case, a tricopter with two servo's that will morph in to a flying wing (two servo's...

I was using angle mode

I have pretty much the opposite problem. When I engage altitude hold, sometimes it will hover fine for a while, but usually within seconds of engaging it, one motor of my Tcopter will be cut and it tumbles to the ground. Its not always the same motor, so I doubt its a wiring issue. Here is one such ...

Vertigo

I assume this works the same for servo's? And is there anyway to mix in other channels besides the default 4 channels? Im building a Tcopter with dual yaw servo's. The servo's both move in the same direction for yaw (props tilt opposite), currently simply using a Y cable. But Id like to use another ...

Vertigo

There seems to be a problem in airplane mode. No matter what I try, the rudder/yaw control seems to be in heading lock mode. With sticks centered, the rudder will not return to center unless the plane is flying at the original heading again (when I last moved the rudder stick). This makes flying pre...

Im surprised I cant seem to find anything on this subject. Apologies if I missed it. My brother is a model rocket enthousiast, and he got me wondering if we couldnt put a multiwii nano in a rocket with 2 movable fins to help guide it straight up. And use the baro for chute deployment. IN theory I th...

I have read most of this thread, and first of all, big thank you to PatrikE I will be trying this on a (yet to buy) flying wing, and a multiwii Pro + MTK GPS that Im re-purposing from my quad. Am I right in understanding that the barometer is not used for RTH ? Or will it automatically use the baro ...

Vertigo

Quick queston; is this setting overriden: #define FAILSAFE_OFF_DELAY 1000 // Time for Landing before motors stop in 0.1sec. 1 step = 0.1sec - 20sec in example if FAILSAFE_RTH_MODE is active? Or will the quad fall out of the sky after 10 seconds of returning to home if I dont comment that out?

Vertigo

I have yet to try this firmware, but assuming it works, Adrian, will you marry me?
Seriously, this is everything I wanted from multiwii, and everything that should have been in there in the first place. Thank you very much!

Vertigo

Hi, The position of ESC is not the only thing to consider. Power wires position and isolation is something also very important to consider regarding EM perturbation. You can fly in acro mode safely if you don't activate mag. it's independent. To be clear, Im having the yaw issue in flight in acro m...

Vertigo

(crosspost from rcgroups) When throttling up, the compass and the figurative representation of the quad yaw to the right pretty significantly. I tied down my quad and hooked up to multiwiiconf to better illustrate the problem: y4OCFfdhMD0 I also moved the ESC wires as far from the FC as I could for ...

Vertigo

that could be if he has enabled it, but it is disabled by default so possibly not, though it does sound like it I did enable failsafe. And it probably is correct that its failsafe kicking in, it also explains the delay. I still dont quite understand why the yaw would be "too low" and trig...

Vertigo

That almost makes sense... and you might be on to something, but it doesnt add up. My throttle remains at min all that time (which is below 1000) and my rudder doesnt go below 1000. And yet moving the rudder to min, close to 1000, it switches to Angle. Moving it back close to center, it disables ang...

Vertigo

Having a weird issue. When I disarm, or try to disarm, by pulling the throttle/rudder in the corner, my controller will not always disarm (may have to try once or twice), but when I hold the stick there for 2 seconds or so, it enables Angle (stable) mode, thereby throtteling up briefly! Releasing th...
