I would go with the 850 mah. The 650mah sags a lot with 1407s. I've actually been running a 1000mah pack and have been getting anywhere from 4-6 minutes but that all depends on flight style.

Thanks! The motors seemed to handle these props no problem. I haven't pushed hard on a really hot day to stress test it yet though. I'll be interested to see how they do with the extra weight of a 1050mah battery.

Great! Got any footage?

No :( I'll hit you up when I get some though. I haven't bought a sd card for my fatshark yet haha.

Just a heads up you get a lot of frame in the shot with the micro swift. I used my soldering iron to remove part of the canopy, it's not the best look but oh well. Love the cherry bomb!

Grrrrr! Maybe I should have gone with the 2.3 lens then.

I'm using the 2.3 lens :x but only with a 28 degree tilt. It might be better at 35 because it was showing in the lower half of the screen.

Maybe the V2 canopy would work a little better with that mount? The extra height on the V3 canopy was added to the bottom edge, so the opening for the camera starts a few mm higher off the carbon. I'm partway through an almost identical build (XJB-425 and 2.3mm Micro Swift in a 4" Atom) so I'll try both canopies and see if one fits any better than the other.

Let me know how it works out!

You guy's keep an eye out on those XJB's. I just had the negative pad lift off while unplugging the battery on my Underpup. If you have a way to zip-tie the leads down, I would do it.

I was trying to think of a way to run it out the back for that reason, but haven't decided how. Good looks!

The largest motor this frame fits is ones with 12x12mm mounting holes. I'm not sure if 1407 is the largest in that class.
