A robot like a featherweight should failsafe if there is interference from above or below. Is that not why the failsafes are there?

I have tested this with antweights i had three running on 665, 675 and 685 all with the jeti rex 4s (know for suffering interference as it runs on 35mhz and 40mhz). I turned off the tx for the ant on 675 and it stoped dead! I turned the tx back on and drove away again.

Also for tech checks are the robots not ment to be armed while on a stand and while havign all locking pins in place?

I dont see why it should be a problem to use frequencies at a 10Khz gap.
