GPS and Compass position

Hello,

My quad copter is Quanum Venture with APM Mini Pro FC.

Also, i hope to install the GPS&compass module.

But i have some questions which are GPS & compass location must be install onto the center?

Venture is really hard to fix the GPS with PNF ver.

So i decide to fix GPS&Compass onto the behind postion that you can see the attachment.

If i install the GPS&compass onto the back position, is there any problems?

Thanks to read it.

i hope to listen good news.

Thanks.

you can mount anywhere on copter.
location will be taken care by compass calibration process.
