this might not be a fair request.. but I wonder if we can get a update to 2.2dev of this.... for tuning.. and it is really helpful as GC when doing AP

thanks

jy0933

does anyone know if the MMC10 is the rebranded FF?

thx

jy0933

i guess i forgot to set the motor_stop

thx guys

jy0933

it is not causing problem..(yet) But will be helpful if anyone can help figuring out why it is like this board, mega2560 loaded with latest dev config.h side minthrottle 1095 maxthrottle 1905 mincommand 1000 tx side minthrottle 1095 (ish) maxthrottle 1900 esc side simonk fw and manually set 1095-190...

a quick question.. it was said beseflight has some problem when using on v-tail ... is it fixed now?

jy0933

yeah.. im talking about complimentary... i mean.. how exactly does it benefit mr? acro or stable flight? also another quicky about mystery and hk blueseries from multiple sources saying they are identical.. but looking at the google spreadsheet... mystery 12A is P/N fet using bs.hex but HK blueserie...

jy0933

stupid question time.. i know i got stupid questions all the time how is the break going to benefit multirotor? from what i have seen.... the break works 1. reduce rpm to desire speed faster; 2. charge a bit of current back to battery... it seems it might help to achieve better and faster response.....

GLB gets some TTL serial sonar now...

i wonder except the connection.. what other differences are between ttl/i2c/ trig-echo?

a quick Q about xbee/3dr radio.. it seems not working with baseflight yet? i tried to hook a 3dr like BT.. but doesnt seem working

jy0933

I believe he means for you to make sure that the Z axis of your accelerometer is set right and reacting properly in the GUI (move your quad up and down while watching the GUI and make sure Z axis moves appropriately.) I did. I cant see the grafics move, but I can see the value changing. (see attach...

jy0933

low side i believe

jy0933

i guess it might be resonating with that carbon/nylon prop.... got similar problem on other motors....i'll try plastic prop see if there is any change

jy0933

sorry... i kept messing up

here's the right link

the vid uses a new F20A removed the cap (the 3 left to pads)

it seems jot.damaging motor.. just sound like broken ... might be problematic when there is really a problem with bearings

jy0933

reuploaded the vid

at about 40s i showed the terrible whining .. any clue why?

also

thx for the tip on turning the safety off

jy0933

as you said.. connected to fc seems improved..(tho still a bit laggy). but another problem came in it makes irritate noise at low rpm(you can hear in vid around 48s).. it's new... the motor and esc are in good condition.. tested with other esc(fw).. no noise IMG_20121129_165357.jpg vid m just to con...

jy0933

it is kind of helpful

so here comes a noob question

i found a pretty new ver of baseflight here
http://code.google.com/p/afrodevices/so ... ight%2Fobj

as read from changelog... it seems the new modes are sync(ed) in r209...

i never dug that deep into back folder..

jy0933

here's a small comparison noted: I DON'T mean to say who is better or not.. just simply run in this problem and reporting it back... not meaning anything other than this set up er9x+frsky radio hk F40A t-motor 2212 980kv haiyin 3s 2200mah 25c clip 1.. wii esc..

boomerang
https://www.youtube.com/watch?v=aKn0LXm ... ata_player

basically gonna need to set Minthrottle of fc to/below min-esc to prevent cutting myself

I'll try to use 3s batt... the vid is with 2s battery ... But compare to stock.. it is still a bit slower..

I'll get back here after tried with 3s

jy0933

we are only talking about the esc firmware... the video i took was rx directly hooked up with esc just want to smooth that lag out towards more linear... and instant.. i do realize it will be destructive stopping motor in the air... what i attempt to do is boomerang.. when quad is in the air.. the l...

jy0933

anyway to remove that feature?

since i'm trying aerobatic.. might have some 0/low throttle maneuver

it is ok if there is no way to remove that tho... i'll just not do zero throttle

jy0933

@dizz a quick question about lagging start up here's a quick video showing what is happening the cap is removed.... it seems there isnt much lag after motor started spinning.... but since it is build for aerobatic... the lag start will cause problem at some point any suggestion that might help to ge...

jy0933

do we have a "how-to" for port mwc to naze32? i feel like to port the new dev myself.. ( i like the horizon mode soooomuch)

jy0933

a quicky.. seems the latest fw has the "complimentary pwm"

is that the new "stick calibration" firmware?

I actually prefer the pwm range set in stone.. which should i choose

thx

same question here... since sr04 is much cheaper and easier to get... why isnt it in the official fork?

jy0933

ok.. all these make sense..

but how about the PID tuning for horizon?

I tuned in acro mode.. then it doesnt seem good enough in horizon mode (just feel a bit "slow" at some point)

but if i turn with horizon mode.. what might be the potential problem with it?

thx

jy0933

i thought it was a common sense not to re-calibrate acc unless necessary (eg,,, temp drift)

jy0933

so the hover drift is not the bouncing up and down when trying to put it into hover?

jy0933

it's been a while I try to figure out why when I set throttle to hover point.. the quad still bounce up and down randomly.. then I finally came across this today (blame myself didnt read carefully enough ... and also maybe cuz english is my 2nd language.. still not good enough) For Aerobatic flying ...

jy0933

oh loll..... i'm so outdated..

thanks guys

jy0933

i did enabled level_pdf

how do i adjust settings (pid/rate?) so that with this mode, I can still have good control?

jy0933

the symptom..... in angle mode.. even max stick input... barely nothing ouput

video...
(did I do something wrong back there?)

thx

a quick update... error after close

not a big problem.. just bothering

jy0933

that is true for indoor application.... i just want to point out for multirotor... most of us fly out door in various flight condition... can be as hot as 30~40c in summer.. and also can be as cold as -10~20c in winter...also various humidity level..recalibration each time before flight (i could be ...

jy0933

one big drift factor is temperature.... how do you avoid that?

jy0933

there isn't (at last from what i know) any implementation for serial ultrasonic sensor. Most of serial/rs232/ttl sensor are from maxbotix and there aren't cheap.... for devantech serial, they all have i2c capabilities too if i'm right ok.. so probably i have some misunderstanding about type of sona...

jy0933

a quick question about the fly modes i saw somewhere saying it will be a good idea to have both horizon+angle on at the same time to get the best stable fly... but when I turn them on at the same time... the stick control became really insensitive. and also wondering if i want to use horizon all the...

jy0933

i was told it is possible to flash rushduino on minimosd to work with mwc... has anyone attempted ?

jy0933

I finally get the back onto mwc (from mpng... ) with latest dev... then i'm a bit confused with tuning with the new modes i assume we still start with acro mode tuning.. just follow the steps on wiki.. not a big problem.. angle mode is basically old level.. i assume just tune the level pid... i have...

jy0933

just a quick quick question.. is the sonar code included in the latest dev yet? it seems there is only i2c sonar.. not the serial ones...

tbx

jy0933

yeah.. of course the balance process is a must.. but sometimes it is just not that ideal... lpf will still do some help after all.. about sensor data log .. i tried to grad the raw data.. but it was not significant even i push throttle above hover point.. it jumps between +/-5... i was thinking if w...

jy0933

i dont find the 64bit in dev pack... but will try when the final is out

jy0933

found a lame fix

i installed 64bit java.. but mwconfig is 32bit ver

it is solved after installed 32bit too

jy0933

i have had java installed but when trying to open up mwconfig it pops up " cannot find javaw.exe" and following with "error callig shellexecuteex()" i have checked i do have javaw.exe installed... it might be java problem or ?? thx SOLVED found a lame fix i installed 64bit java.....

jy0933

i'm trying to figure out which freq lpf is the best go with for best result. then here's what I got.. I dont know if it is a right way to do it.. assume the motor is out of balance.. 1. the first thing is to find the motor rpm at hovering, assuming N 2. consider this is the hovering, we still want t...

jy0933

did checked with gui since i have BT on when tuning

jy0933

i guess i should probably restate the problem for clarification. the original problem is that after well calibrated acc. WHEN TURN ON AUTO-LEVEL.. AFTER PITCH/ROLL, THE MR GOES BACK TO LEVEL SLOWLY . and I was looking for the solution that the return to level can be faster. (like APM/mpng, after rel...

jy0933

i guess might has to do with D?..

i was using APM recently... apm suggested to let rate I=0 so it wont hold the angle and use auto level P to make it work...

jy0933

i believe the rate climb/decend on alt hold is similar to this that i wrote
might be my thought a bit over..

2012-10-13 Rev1:
redo the motor mount so that the most motor can have the wires point toward center

jy0933

one of curious is .... mwc do not have a "no throttle input = hovering" feature... yet?!
