@quadlifepro yep forever... well, finders keepers it's somewhere on the bottom of the river.
@las Well as you know, the BR1103 have no screws to attach props. I finished my replacement build a couple of days ago, using cut-down 3025's, and put on a layer of uv resin in the holes to have them fit very strongly. Flies great so far, didn't come off. Of course I also have now a loom band on every 2S battery to hold down the balance plug.
I don't have any telemetry, I'm using a DX7s, and I'm pretty sure I could even fly behind the bridge (but that would be asking for it). I've flown at the same location with the QX90 several times, and a couple of years ago with the excellent UMX Carbon Cub, same Tx, no issues (LOS):
@Bobnova I'm pretty sure I lost one of the rear props, thank you for your confirmation. I've never yet have had a failsave with my FPV micro-quads, the video always goes first.
This happened in the first week in January, too cold to go swimming. And it looks like it fell pretty much behind one of the big pillars, and though I happen to swim there in the summer, I wouldn't dare swimming behind one of those pillars. And it would be very difficult to dive down to the ground and find the right spot - it's a river, impossible to go against the current.
