Re: stable mode tuning

Seems like if I have Pitch and Roll P high enough so the QUAD doesn't move.. if I wiggle the stick or a gust of wind cause it to tilt more than 20 to 30 degree or so, the FC goes nuts and flip the QUAD. If I reduce the Pitch and Roll P low enough that it doesn't flip, it wants to drift.

stable mode tuning

I adjusted PI in level, the quad seems to more or less stays in one area. I was trying to see how far I can push the quad in this mode by rocking the quad with the stick. Once I got it going using stick movement, it flip. If I am in ACRO mode, when I rock the stick, the quad respond and does not fli...

ALT PID

I don't seems to be able to get this perm set. When I switch the baro on, the quad will start to do a slow yoyo effect. I started to decrease P to 2, than on one of the yoyo, it shuts motors. If I increase P to 5, it also shuts motors. The yoyo rate remains the same no matter which direction P chang...

With the suggestion from icedfusion to set the ITG3200 low pass filter to 42hz, the machine will fly now.

Thanks for the reply.. there are spinning the right direction.. just the CW ports are having the problem. Since the problem follows the port and not the ESC and motor, I wonder if a step I missed somewhere.

thanks

Also you need to caibrate all 4 esc's with transmitter and plugged in the throttle channel with the props off motors so you dont cut yourself!!! The motor wires are already swap.

CW motors not spinning correctly

I hope this is the correct forum for this, sorry if I post in the incorrect area. I just completed a MultiWii 2.1 build using a RCTimer RM450 2830-1000KV 30a ESC, Crius SE v0.2 board.

Re: GPS integration

glad to hear that, it would be great if you could test if battery would hold from weekend to another(6-7 days), that's about as long as we put our models unpowered, if it can only hold a day or two... it's too short. EOSBandi EEPROM hack is 'a must' then. thanks or replace the ML614S with a ML2016....

Re: GPS integration

2 dr.tom,
Thanks for the info, what MultiWii board are you using?

According to RCTimer's picture of their i2c interface at their website, it is pluged into the CRIUS SE board's UART port. Can someone confirm if this is correct?

Thanks for your time.

@ dr.tom, The flytron looks like a serial GPS?? no??

Did you connect that to the rctimer i2C board? if yes, what code are you using on the i2c?

thanks for your time.

Board currently being used are CRIUS SE v0.2, CRIUS GPS serial, CRIUS i2C NAV board

Hello Patrik,

Is there a way to remotely change the rate if the FC? I see some of the commerical 3 axis gyro can change different rate for different flight condition. Would be great if somehow that can be done with the MultiWii..

Re: Helicopter integration

If there is no collective input from the Tx and since throttle is used for alt control, I don't think there is much use to have the collective servo route thru the multiwii. I guess the Tx can manage the collective pitch curve. Will need to make sure level mode is switched off during take off and la...
