The two Firehouse Arc V strobes weigh about 13 grams each. I don't recall but I think it was the multicolor (red, green, blue, white) that is slightly lighter than the other. The Landing Gear for Mini 3 Pro weighs about 22 grams.Thanks for this. The gear seems to make this all work out. Is that gear generally pretty light?
I have an ARC V and put it on the back of my battery door, due to lack of any better option. I experimented with the top placement which was okay, but the bottom would certainly be better.
A couple notes on the Firehouse Arc 5's...
1. The adhesive on the back of one set of the Firehouse Technologies Velcro from was dried out and weak until I used a little rubber cement I scavenged from a spray bottle and that solvent in it reactivated that on the Firehouse velcro. I would have used a 3M Command) device that is like "ULtra knobby velcro" (used to hang frames on walls, etc), but I didn't have any at the time. I think the Velcro brand stuff is better, too. Upsides to the knobby stuff are that sand and lint won't be a bother and that the light won't come off in flight. Downside is it takes a bit of pressure to get the stuff properly engaged.
2. The multicolor Arc V is not as "snappy bright" as is the all-white version, but when mounted on the bottom I have found that using different colors in different conditions is helpful. I also find the white flash/strobe combo setting is great.
