These propellers are engineered with wingtips that reduce vortices around the edges of the propeller blades, leading to increased efficiency and reduced vibrations.
The new V2 "S" version has a stronger material and a chamfered hub to further increase durability.
I was encouraged by the reviews here & the brand image of NBD making good products, but this kit is straight garbage. The drone itself is great, I like how it flies and the simplicity of the board yet as a kit it just falls apart. In just a week 2 motor cables tore off, vtx cable tore off & it's not repairable without messing up the camera pcb as they have some kind of clear coating on some part of the board. Had to order a new camera. Another issue is my drone came with one of the canopy screws & the grommet missing - for a beginner kit like this small hardware like this should have replacements included. No wire harness for the external receiver is included as well as you'd get if you purchase Beebrain separately, which is puzzling because no UART pads are labeled on the pcb nor the online material besides that port they've done.
The worst offender is the goggle. The antenna connector came loose in just week - no accidents at all. I wanted to open up the screen to see what happened - you have to destroy the thing to access the screws. Very unfriendly for repairs. When I opened it up, I saw that all 5 pins came loose on the connector - & all pads lifted. How can this happen without any damage to the antenna, in a week? I mean if you tried that hard to prevent people from getting inside your product at least make sure your build holds up.
The charger they claim it's their own injector just with a different enclosure - that's not the case & this is false advertising. The charger that's embedded in the goggle doesn't do HV, which their own batteries run at.
I really hoped this would be a welcoming entry & a decent quality product but nope - after going through all these I can't really suggest this kit to anyone. I don't think NBD was going for a nice piece of kit, & the QC is definitely lacking.
Bought 2 of the bind and flys and 2 of the V3 flight controllers separately. Flying these out of the box is really fun, they fly amazingly well and have a lot of really nice features. After the first board died I figured it was just bad luck, but after buying 3 more I've had the same or similar experience with all three:
First one VTX fried after 3 weeks, second one the U.fl connector ripped off the board and trying to repair it made it worse. Third one the SPI receiver decided to just die on me one day, and the fourth is still semi-working but has intermittent power issues.
Support did give me a 50% off code for one of the boards, but other than that it has been pretty much sorry tough luck - you must have done something, etc (fair enough, I know it's hard to warranty).
There is a problem with AIO whoops boards in general having durability issues, but I think if I'm going to pay $100+ for a FC I want to have some kind of faith that it will last a while. It's also really frustrating to have different camera/motor plugs than literally everyone else in the industry - it's not a good look for anyone in the FPV game.
Bottom line is: I do love the flight characteristics and feature set but I just can't keep throwing money at it and watching the paperweights pile up.
