Please remember, a tech check, is a check, and is in most cases the most dangerous activity at an event.
This is where we find out if a robot does or does not comply to the rules.
A robot is not forced to work, including failsafes until it is passed, and even then things go wrong.

To have a 100kg robot on a cradle wheels spinning in all directions, locking pins being tested is not the best idea. And has happened in the past due to interference.

And so for safety reasons, we will always run frequencies 2 apart while tech checking, to minimise any risks.

Many Thanks
