Default Where to install the video TX?

I have a dji f450, my 2.4 ghz futaba receiver is install on the lower board on the back, is it ok if I install a 900 mhz or 5.8 ghz video tx right under where I have the futaba receiver (on the other side of the board, the futaba is installed on the up side of board and want to install video tx on the down side)

Is there any risk of interference between the 2?

I think having any frequency TX close to the rx is risky. I have "overwhelmed " a 2.4 rx to the point of brown out by having a 1.3 video TX maybe 6" away

Should not be a problem.

I run my Video TX about 3" from my AR12020. (I do have 3 satellites though).

But even in the log, I have very low drops.

When I had my F550, the AR8000 was directly under the video TX and I ran it to 4000' without too many drops either. (900MHz 800mW output)

Unfortunately I run a futaba r617fs as receiver so no log on packet loss, am I right asuming that worst case scenario, if there is interference, the failsafe will kick in right? I have failsafe setup right in receiver and naza

It won't kick in for interference, but if there is packet loss for more than 6 sec (unsure if 6 or 10s) then the failsafe will kick in (RTH or Land)
