Hi all !

I build an y6 frame with alu and i tried to make it fly with 2.0.32 but it was completly not stable even when i tries to change the pid rate !!
Finaly i ve decide to try the last 2.0.34 to see, and surprise my Y6 with 90 degree between front arms CAN fly !!!!
I ve made a video yesterday so you CAN see the results.

Looks jumpy :) Why 90° between front arms ?

For 90° you need to make changes in the code... If I'm not mistaking..

In motors_y6.pde change this:


int roll_out = (float)g.rc_1.pwm_out * .866;
int pitch_out = g.rc_2.pwm_out / 2;

TO


int roll_out = (float)g.rc_1.pwm_out * .707;
int pitch_out = g.rc_2.pwm_out * .707;

Thanks Max i Will try this modification of the code ? But Could You explain ( just to understand )
Why 90 degree ? Because the look is better !!! Looks like a tirex :)
