Yesterday, during the thermal testing, I had the beacon on the M2ED for safety as sunset was coming on. Wow. That thing is BRIGHT and makes it so much easier to see the drone. I've decided that's the accessory I'm going to leave on the M2ED all the time until I need to either switch to the Loudspeaker or lights. It's great that I can switch it on or off as needed. When the M2ED is at distance and a mere pixel in the sky VLOS, turning on the beacon (even in mid-day) makes it so much easier to see. It's nice that it also meets the FAA requirement for anti-collision lighting.
