I bought the ArduFfyer kit with GPS and Telemetry from RCtimer.
Have not put in the frame yet, just leave on the desk for testing.

How come when i connect the GPS it interferes alot to the board.

Here is the tuning monitor
No GPS
[attach=1]

With GPS
[attach=2]

Then i used the aluminium foil wrapped the GPS, then no interferencence
[attach=3]

I tried to move the GPS around but no help. The GPS cable connect to the board just 6 in long, do we need to extend it.

How can you fix that problem.

Thanks.

I had that same GPS using with the Crius AIOP, but no interfere at all, even I mounted the GPS right next to the AIOP board.

Tried with another gps module, got the same probem
I noticed that it just happened when gps got 3d fixed
I downloaded the latest arducopter.
Problem solved.
Do you got that same problem with 2.9.1b ?
Thanks.

Ive been using v3rc2 and rc3 but when I had v2.9.1 uploaded I did notice the HUD hqad a weird slight wobble that had no affect while flying I wonder if this was the same thing, it doesnt do it now  :shrug:  ~~

You are probably worried about nothing. Those little wobbles you can see are probably filtered out in software, its how it flies that';s the main thing. Get it in a field, get a decent lock and put it up in a loiter to see if it';s working right.  ~~

You';re worrying about nothing. You';re seeing the result of centrifugal force correction based on the gps. In 2.9.1 this happens all the time, so we get lots of ';why is the hud moving'; type questions.
In 3.0, this was disabled when the copter is disarmed just to stop the questions. See this commit

This my first time to play with it, so just want to be sure before bring it up to the air.
