Looks like you must use Servo which supports 490Hz PWM rate.
Tri servo shares with motors same hardware timer. So if motors running at 
490Hz, servo also running at 490Hz.
Maybe we need to move servo output to other channel with separate in next 
release...

Thanks you very much Alexey for your fast response. ;)
i use for my tricopter test , a simple HXT900 9g / 1.6kg / .12sec Micro Servo. 
i'm very interresting for use this , because i have another tricopter on 
multiwii firmware. the servo work fine on PIN 2. 
What make for change assignation PIN ?
On library or arducopter folder.
Many Thanks for next responses

Could you please, try new MPNG 2.9 R6 available in SVN?
In this version motor connected to D6 moved to D2!
So now all motors running at 490Hz and servo at 50Hz.

Hello Alexey,

Thank you very much for your exellent work ,and i have downloaded and tested 
the firmawre.it is much better.a little more stable

On my aio bord i have the same problem .
the yaw servo heats and vibrates.
the yaw servo is unstable.

Connextion Crius AIO bord for me : 

tail engine = 3
left engine = 6
right engine = 5
servo motors = 7 ( on multiwii firmware 2 )

best regards

Looks like you downloaded old version. Left engine must be connected to D2 in 
new firmware. New version is 2.9R6 and available only in SVN!

Tricopter OK, but MegaPirateNG 2.8 R3 can only digital servo (=7)

Hi,  I've found a flaw in the megapirate code when using a Tricopter setup and 
powering the board via a BEC.  No 5v power is being supplied to the motor 
outputs as a result yet the servo needs 5v to operate.  I connected up a 
standard rx 4.8v battery to test my theory and the servo works fine.  Because I 
am using multistar SBEC escs I had to use the external BEC for power.
