I have a strange problem with stable mode. When flying in normal mode my quad is really stable. But after I switch on stable mode, front left motor immediately spins at full speed, when throttle is applied. The other 3 motors are spinning as they are expected to. ACC is already calibrated and shows correct values. Any ideas how to solve the problem?

Thanks in advance ;)

Problem still exists, but I've tried v1.6 and there stable mode works normally. So maybe there is a bug in v1.7pre?

hi , im also have the same problem when turn on stable mode.
im flying quad with home made aluminum frame. now using default v1pre7, without stable mode flying rock sport!!..

When you have good PID and can hover level in acro mode, you then need to trim Autolevel.


Disarm copter

Move throttle to full

Use pitch/roll stick to trim level mode: Each time you move the stick fully in one direction you add one click of trim in that direction. The LED on your board blinks one time for each click you apply.

Lower throttle

Arm copter, fly

Repeat procedure until you can hover level in stable mode!

Here is my latest autolevel test with Flyduino and FreeFlight IMU on my quad. Flying with unbalanced load in form of a 172 gram battery strapped to one arm:

This is still with stock PID, so wiht some additional tuning, I think I can get it even more stable than this.

Alex...Pre 1.7 is a masterpiece! Autolevel is indeed working very well now....

I found this line in the .pde and wonder, what it is good for.

Code: Select all

  #define LEDPIN_SWITCH              PINB |= 1<<5;     //switch LEDPIN state (digital PIN 13)

As far as I know, the PINB register is read only and cannot be written.

Hey guys.
I just tired running the 1.7 with both the NP and nunchuck. I'm still waiting for my tx and rx...
In the Configurator, when I tilt the quad, the roll indicator stays in place. The Pitch indicator however, will move to the angle that the quad is at, the drift backwards, PAST level, and settle at the same angle, but past level. (Say, I tilt the quad 45 degrees back, and the pitch will point upwards, at a 45 degree angle. The will drift towards level, and settle, with the pitch arrow pointing DOWNWARD, at a 45 degree angle). Is this normal? Also, my Roll Pitch indicator (The Black circle with the white arrow inside) does not respond. It stays pointing straight up...
Please help! this is my first time using MWC. Thanks!

I will upgrade my quad from 1.5 to 1.pre7.

If I leave all the PID config in 1.7 as in 1.5, will quad fly the same in acro mode?

If you mean released it's a long time ago.
All releases can be found here.
And if you look in the trunk there is the latest Development releases to be tested.

OK I was looking for a release announcement / thread for it here. I suppose we're just discussing it in this thread.

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 trim the level mode according to the neutral angle you want to change. The status LED will blink to confirm each ticks.

1) How many ticks are there? 100? I had to about 10 left roll and 5 pitch back ticks to get it level. How many are possible?

2) In the conf, what does the numbers with commas mean? How do I adjust each number? In the past I would click drag to go from a negative to a positive number.
