tested with that line uncommented and it still was unflyable. tried that as well as the next one up and it was unflyable. works great at 42khz even with the default pids. dialed them in a bit and have it flying pretty good.

captaingeek

i have both the flysky th6 (same as hk 6ch v1) and the flysky 9ch v2 *same as t9x). both are very good radios.

i'm interested in using the ppm signal on the bat connector. anyone know about that?

captaingeek

if there was a way to set the PID's so that when you went full throttle all motors would goto MAXTHROTTLE and stay there that'd be cool. I havn't found a way to do that yet (maybe if you 0 all the pid settings?) because when you go full throttle they get close to 1850 then move around a bit or slowl...

captaingeek

will test

#define ITG3200_LPF_42HZ

later tonight.

captaingeek

Another observation (full throttle): With PID's properly set and holding quad firmly on the ground (soft carpet) I can see engine commands jumping between 1800 and 2000 (more time closer to 2000), when I'm holding quad in my arm those values are moving between 1300 (MINTHROTTLE) and 2000 (MAXTHROTT...

captaingeek

pretty cool build. question - id like to know how you setup the ppm with the radio? how did you configure it? I have the same radio.

captaingeek

fyi - with eosbandits code changes it flew great with the inertia 1. level mode works great. mag mode works. flew pretty well with all default. and this is a quad with 18" arms thats a bit of a pig. thanks alex!

captaingeek

uploaded the new code. made some minor tweaks. uploaded... tested orientation through gui config... and... FLEW AWESOME! first try no changes to the PID's - flew like a charm, thanks! what did you change? -tested level mode. again was surprised how dialed it it was without any tweaks or trim. mag mo...

captaingeek

interesting cause im running the same setup. i beleive the cap is to limit any voltage drop from servos. is this a quad? can you share you pid settings?

captaingeek

thanks! will test tonight.

captaingeek

since your just starting maybe go with a cheapy. you can get the flysky 6 channel for about $50 or the flysky 8 channel for around $70. both are good readios and come with an RX.

captaingeek

great! thanks. so this just adds the changes for the LPF? thanks for the help. I'll try tonight.

which version of the gui config should I use?

captaingeek

i got it working with ITG3200 defined only somewhat in 1.7. its very twitchey. can only hover for 10 seconds. what kinda pid settings are you guys using iwth this board?

captaingeek

let the battery run down to far nice flight! wish i was there i have all the fpv gear i need just not quite dialed in yet.

what do you mean by 0607?

captaingeek

im not convinced that its not a problem with the esc's. Im testing a new paris v4 board with an atmel inertia 1. i use a seperate BEC to power the board. I've cut the 5v lines from all the esc's. maybe they need that to operate. in order to calibrate, i power the board via usb, activate the controll...

captaingeek

thanks a lot!!

captaingeek

can one of you guys please zip and send me the version of multiwii your running with this board? or post it here?

captaingeek

cant seem to get mine in the air with this version. doesn't seem like its outputting enough power.

captaingeek

so should i download svn/ trunk/ dev_version/ MultiWii_dev20110714.zip extract, then over write those files with the latest revisions and upload?

What about the config? should i just use the one in svn/ trunk/ dev_version/ MultiWii_dev20110714.zip

captaingeek

tried with the latest rev on my quad x but it was jumping a lot. going to try with 1.7. Is that possible?

captaingeek

which one is currently the best dev version? I have the atmel ave i1 here i'd like to test fly his weekend. i understand that max correction will be dropped?

captaingeek

is it just me or is the gui config much smoother in this version?

captaingeek

thanks pat. im now running the same power plant in a different layout. its still a quadx with 18" arms. its pretty big. i was overloading it before causing it to bog and to fall when the batteries were getting low. with my current setup i can run for about 10 minutes on a 3000mah battery or 6+ ...

captaingeek

got this working with the dev code last night.

the config is super smooth with this board compare to my wmp/adxl 345. The sensor readings, the gui everything seems to be super stable and smooth. Im seeing 3000 cycle times.

can't wait to put this thing in the air. awesome!

captaingeek

what ic2 speed are you guys running your I1 boards at?

captaingeek

very cool will test it out.

captaingeek

wired it up last night. im not sure how to configure the dev code.

Is this the code I should be using?

http://code.google.com/p/multiwii/source/browse/#

http://code.google.com/p/multiwii/sourc ... 110714.zip

I tested it with 1.7 and it seems to be working OK.

captaingeek

just got mine in the mail today. debating on waiting until 1.8 goes gold or to try a dev version. I'd prefer to just use the boards headers but i see others have soldered directly to the board.

captaingeek

I scrapped that one and built a new one: m Question regarding a large quad's a yaw. my current quad has 18" arms. It has a tough time with yawing. in high winds or during stick input it does yaw OK but is loosing altitude like a rock. any suggestions? should yaw rates be lowered? or am i just c...

captaingeek

I have this radio working as well.

Question - on the RX, arent all of the GND and 5V pin's bridge? In that case you only need 1 connected.

captaingeek

wow this is a great deal. so this will replace the wmp, nk and provide baro / mag as well?

captaingeek

Got some wild turkeys on video. Still trying to get rid of vibrations. I had to run this through a video processor to get rid of some of the vibrations which is why is looks a little soft. http://www.youtube.com/watch?v=O011WVxQU58 I think if I lighten my frame a bit and extended the arms out more I...

captaingeek

A suggestion on the failsafe code - once signal is lost, after the heli lands, can you blip the motors? This way you can find your copter if it comes down out in the woods by hearing.

captaingeek

but you could continue to use the mwii if you just connect the appropriate channels to the ESC / servos for fixed wind and just shut the motors off. when hovering just leave the servo's connected and active.

captaingeek

currently working on getting this unit working with the mwii

captaingeek

once autolev is trimmed do you find you have to trim again later for drift or due to lower lipo power?

captaingeek

im very curious about the hockey stick frame... isn't that kinda heavy?? May have to look into this. Where the heck i'd find a hockey stick in Cali I have no idea.

captaingeek

that looks awesome!!! not sure about the coding, but I think if I were to try this I would to it all through radio programming. take off and land using the triwii as normal. When you want to transition to plane mode, just use some servos that tilt the front 2 rotors down that. fly the plane normally...

captaingeek

OK check out these schematics. Generally its recommened that you only use one of the ESC's BEC's.

lots of really cool new stuff to play with namely the autolevel mode, software trimming of autolevel mode, and failsafe. I've began testing and have been quite surpirsed how well everything is working! Well done!

captaingeek

Specifically for discussing v 1.7: 1.7 list of differences with the 1.6 ALL: BARO is more precise, but still not perfect (1m to 2m amplitude). Note it's a code issue, not a baro component issue. ALL: RC channels AUX2, CAM1 CAM2 added. only relevant for PPM SUM stream or MEGA boards. On the 328p with...

captaingeek

OK can you send a link to that schematic because I dont know what that is. Are you powering from one ESC or all ESC's?

captaingeek

2 questions: MAIN SOFT: software trim for stable mode It is now possible to adjust the trim of the level mode to match the same TX trim used for the acro mode. 1) disarm the motors 2) full throttle (must be >1900) 3) full PITCH forward/backward and full ROLL left/right (2 axis possibilities) will tr...

captaingeek

Check all grounds and wiring. Which schematic did you use? How are you providing power to the mw?

captaingeek

I can't beleive how great this thing flies using the default PID settings! Tonight I'm going to try to mess around with the auto level mode a bit more. Great work Alex! new quad: m flying: m a little more room and sportier flying: m can it lift a 32oz snapple? m Any feedback appriciated especially s...

captaingeek

are you able to backup the database? If you want I can setup a phpbb site on my server.

captaingeek

How's it fly by the default settings? Maybe try go back to default, Lower I and increase P a bit.

Here it is flying:

http://youtu.be/BldnH1aXNh4

I found that it will almost drop outta the air if I hit the yaw too much. Gotta get that figured out and do a small bit of PID tuning before I setup stable mode.

captaingeek
