No, it won't be flyable at all.

I'm looking for a source for 3x2 props, CW & CCW. The ones from HK got bad reviews.

ACC was on.

Acro mode? How do you turn that on/off?

acro mode is gyro only mode it is just called acro mode by multiwii users

try it without acc, i think it could be a calibration issue, did you calibrate your gyros, acc and magnometer?

i saw your video, it seems lik your baro acc and mag was on, i think you should turn them on, if even on of them is not calibrated properly, this can happen

Check that the board is correctly oriented on the board, that your motors are connected to the correct outputs, that the motors are spinning in the correct directions, and that each motor has the correct prop on it.

I Have an interesting problem that maybe one of you guys can help me with. I have a goodluckbuy x525 in the X-orientation. A short while ago one of my skywalker 20A esc's went poof. I replaced it with another skywalker and now whatever esc is hooked up to the multiwii pins D11 stutters on startup and doesn't spin like the rest. It will take off but rotates constantly and drifts--presumably from bum signals to that back motor.

Inside the GUI everything shows as fine but I think something is wrong with that pin.

My question is there any way to use another pin (D5,D6) instead of D11?

Yes I have re-calibrated all the esc's, balanced props etc. and the problem is confined to whatever is hooked up to D11 and not to a particular esc. I really don't want to buy another board when I haven't even got one flight from this one

Hi:

I have a MultiWii Crius with 2.1 version mounted on a F450 DJI frame (hobbywing skywalker ESC 20A and XXD 2212 KV1000 brushless motor). Please, anybody have a screenshot of the multiwiiconf of a similar configuration?

My quadcopter is bouncing

Thanks a lot

You need to PID tune it.

Can you describe how it is bouncing?

What props do you have?

I had that bouncing that you have--I had the esc's calibrated to the wrong channel on the radio. After plugging them each into channel 3 and re-calibrating, it went away--maybe you did the same thing as me by accident?

Hi menace,

Here's how to change a motor output in 2.0:

Let me know if any of it doesn't make sense.

I havenīt any video, but I can see that I think the altitude sensor not working properly as soon as it goes up as goes down.

Hi:

I think that I have calibrated properly the esc's but I will check again the next days.

Thanks menace69 and TS00

Hi there,

received my Crius SE v1.0 upgraded version today and loaded my normal SE v0.2 sketch to it. Everything worked fine for like 15mn when all of a sudden it would start to give me tons of I2C erros and all sensor-readings would stop.

I have tried to reflash the sketch and clear the EEPROM... does not work... tried to downgrade to 2.0 and 1.9.... does not work... always showing me tons of I2C errors.... the value jitters arrount 20.000 or so...

Any ideas?
