I remember A time when my Phantoms 2's would hover in one place,  

Phantom 2 + Lightbridge + New 2.4 Controller is drifting hard RIGHT
My other Phantom 2 FPV set up is also doing this. Both I have updated & from what i remember did not do this before


I have preformed all compass calibrations & Adv cals on the units & passed.
It seems like there is no GPS lock, but i get the 3 greens before flight. My lightbridge says 4 Sats.


these are my Gain settings.


170 PITCH


170 ROLL


135 YAW

135 VERTICAL

120 ATTITUDE P

120 ATTITUDE R

Any Ideas ? thanks

4 sats is too low for proper GPS stability. did you ever crash this craft?
post up some pics,especially a close one of the phantom top down

Hi Adrian,

have you checked the center of gravity of the aircraft? Have you distributed too much weight of those add-ons on the right side of the aircraft?

If above cause has been excluded, it could be due to the little satellites signals? Could you pls try to fly in a place where there are engough satellites to see whether this is the cause?

Hey heres a pic ... I mean it could go to the left a little bit but id say its very close to the center.

I will let you know after a flight in a more open area with higher GPS readings..
