Frequency for PID computation

Hello,

1ms, 10ms, 100ms?

 

It seems ESC for Brushless motors can't change values under 20ms, so it is not necessary to compute PID quickly?

Why not use an Arduino Pro Min

What RF

I'm using 2.4Ghz rx/tx.

 

Using 900Mhz for telemetry.

 

Question is, since the rx/tx is spectrum, shouldnt I also be able to use 2.4Ghz for video, or would it stll cause interference?

 

If so, what frequency would be good otherr than 2.4 and 900?
