    "2nd purchase of this drone because i lost it flying at night"

    Ronan (5/5)

    "The specific one I got had build quality issues, have to remove jst pins from motor pads and solder motor directly because jst fell off. That being said if you got one with good build quality it’s a great flyer."

    "Flies beautifully even with a massive camera on top, got it to carry a 200g camera like a champ (wouldn’t recommend it tho), it can take a crash like it didn’t even happen. 10/10 would definitely recommend"

    Crux 35

    "Absolutely awesome, set up my transmitter and bind it flew on stock setting just put my rates in it and it flew awesome. I’m ready to buy another one. I couldn’t be happier. The only other thing I had to make changes with was the camera. I turned up the brightness because it was set pretty dark , the tool came with the quadcopter so that was no big deal and it’s probably a personal preference choice for the brightness. No fault at all. I have 50+ flights through it with no issues can’t go wrong with this one. It’s very light and the tune is great."

    MAtt h. (5/5)

    Weak and feeble

    "It’s not durable at all the frame breaks extremely easily and to replace an arm you have to replace the whole frame. The motors break and fall apart easily. Would not recommend, I was quite disappointed with this quad. It does have good performance for the price but the durability is to much of a sacrifice."

    Q&A

    Can this run turtle mode?
    Yes, But it can cause issues with over use. I have burned an ESC while trying to turtle in tall grass.
