Just add a bit of tape. Sanding is the proverbial sledgehammer on such small props.

I took my mQx out a couple nights ago, nice light 0-3 mph winds for some circuit flying and head-in practice in my front yard and street. While hovering above the front lawn, I had a visitor appear, dart around the 'copter a few times and zip away. For a total of four visits, the hummingbird flew formation with me in hover before he vanished. Sadly, no video, since my flying is usually unremarkable, but that night was amazing!

I had a big hawk swoop down and try to grab the MQX as I flew it in my backyard once . It landed in a tree in my neighbor's yard and watched me flying for almost 15 minutes. I tried to coax it out by flying within 6 feet of where it was, but it just watched. When my lipos were dead and the MQX was grounded, it took off.

Holy smokes, batman! I suppose it's lucky for you that the bird decided it wasn't a tasty snack. We have hawks and eagles in this area and I had an eagle land with lunch in our back yard. My wife spooked it a bit and it flew away with its kitty snack in talons, leaving behind tufts of hair. I'd hate to see pieces of mQx at the base of a tree!

Oh man! A "kitty snack"? My wife would freak.

I wonder if an eagle would go after a flying cat like the Orville-Copter posted earlier in this thread.

If I ever finish my MK Okto XL, I'll have to consider a flying squirrel costume for it. I probably should arm the copter with some form of protective weaponry before flying it around raptors.

This has happened to me.
I find that adding heat (I use a trim cover iron for Monokote, etc., but I remember using hot water on plastic frames of glasses)
makes it easier to bend and more importantly let one bend repeatedly without breaking (I did this to a GWS slow-fly prop many many times).

I decided to try the sanding method anyways and I am quite happy with the results!

I used 600 grit sandpaper that I cut into tiny pieces. it took a decent amount of sanding and checking before the blades leveled out, so it was easy to get a nice balance without ever having to go back and forth between sides. it required a decent amount of pressure, and a fine white powder would appear. since the markings are so fine it’s not really noticeable aesthetically, and I like the idea of reducing weight on the blades rather than adding. took me about an hour total, so it takes a bit longer than adding tape I'm guessing.

as noted earlier, I noticed the heavy blade was always the one with the A/B letter on it (although I still checked each one), which made it easy to know what side to work on without marking the blade

I attached a pic I took after doing two blades, so you can see how much material came off. I went back and sanded the orange blade a bit more after I took the pic

On-board video

Here's a clip I shot this evening with the #16 cam mounted under the belly. Just some slow flying around my north yard & backyard. I've flown with my old #3 cam a few times, but this is the first time I've flown with the #16. I did notice that it's a bit easier to get into vortex ring state with the heavier cam. I balanced the props, but there's still a bit of harmonic vibration. Be sure to watch in 720p.

What do y'all think?

Eflite mQX on-board video - 808 #16 cam (4 min 55 sec)
