Strange behavior of motors

Post by Hermios »

Hi everyone,
I mounted a quadx, my board is a nanowii
I uploaded the program Multiwii_2_3 with both those specifications (quadx, nanowii).
I monitor my Quad using Multiwiiconf
My problem is, the motors react strangely
1- Only the Throttle has an action on them. Other movement (roll, pitch, yaw) have no consequences
2- To "arm" the motors (I'm not sure that it means what I think), I need to move all the sticks randomly during maybe one minute. Then, the motors start to work
I didn't find any specific sequence to start them.

I know for sure that the problem is purely software (The monitor shows me that every action of the transitter is recognized, and the values displayed of the motors correspond actually to their behavior). So it can come from the software himself (Yes, theoritically, but I know it doesn't) or from me(Yes, it is!). Now, the question is, what did I do wrong
My values are the default Values of MultiWiiConf, and as you maybe already noticed, I'm a beginner!

Help!

Thanks a lot
Niko

Go read the MultiWii Wiki for how to ARM using stick commands.
Also read how the TX's stick needed to be setup.
There is a beginners section.

Make sure that you've calibrated all ESCs

Also while having the quad on a still surface, press calibrate ACC
Make sure all your radio channels (Throttle, Yaw, Pitch, Roll, etc) has a range of less than 1100 and more than 1900

After every time you turn the flight controller off and on (or replacing battery), calibrate the gyro by leaving the quad very still on any surface, then perform the stick movement to calibrate Gyro

When mounting the IMU, make sure there is a little bit more vibration dampening than you would need.

"Arming" the quad will put the motors running at idle speed, at this speed, the quad will not react to any movements. However, when you increased the throttle a little bit, it will start reacting, hovering, and hopefully flying.

All of these are important so don't skip anything. Good luck man
