    Hello,
    Is it suitable to Eachine QX70? Will it increase performance comparing to stock motors?
    Is it for 1S or 2S battery?

    Thank you in advance

      Yes it’s perfectly suitable … but 1s only. Yes should increase poweer of your QX70 but the best advice I can give is the swao props for the Hubsan triblade model for example (after trimming them). Check the mod section of my QX70 review
