I got my Arris V2 C250 yesterday... I flew it once and the quad let the battery go down to 12.6 Volts....Isn't that too Low? how do you change the low battery warning threshold? you went thru that part a lil fast.. i don't want to hurt my batteries. It looks like it's set at 11.1v "Ext. Alarm" right?
Great review! I ordered this radio system for my racing quad. I was wondering telemetry set up. I am not sure if I can use any telemetry module with this radio system. So, I learned I need to use PRM-01 / 02 / 03, one of these radiolink telemetry. But the problem I found out, they are compatible only PIX and AMP flight controllers. Is that true? PLEASE SAY NO :/ I have SP F3 integrated OSD flight controller on my quad. Can I still have telemetry with this radio system and my flight controller? How should I set up?
Dyrbo Lee There is little difference. The AT9s has additional protocols which make it less susceptible to interference. The AT9s is not compatible to older receivers. Though the radio is a design upgrade it is not significant enough to warrant a replacement of existing transmitters.
