NEWS: Eachine US65/UK65, the new 65mm brushless reference ?

The URAV UR65 was my last best personal choice and represents the best combinaison of electronic ingredients to produce a real powerfull 65mm brushless tinywhoop machine. Here is a new slight variant durectly branded by Eachine, the US65/UK65:
It’s more less excactly the same elements, i.e. the great Crazybee F3 but now directly flashed with Betaflight 3.4. The ESC are rated 6A and also flashed with a turtle/esc buzzer compatible firmware. This new model now integrates some 19000Kv SE 0603 motors… so 2000Kv faster versus the UR65. Another advantage versus the UR65, the 700TVL AIO camera is now Smart Audio compatible… so all Vfreq, Vband selection can be done directly from the OSD. As for the other model, the Crazybee integrates two choices of SPI builtin receiver. A FrSky D8/D16 and a Flysky AFHDS-2A. Be aware, if your FrSky radio is flashed with the EU firmware…. it will probably required to flash more the international version. The US65/UK65 is proposed in a bundle with three LiHV 260 mAh batteries with 40C of discharge rate. This machine will be probably a future hit … and is slightly cheaper than the UR65.

    Avec SmartAudio et tout !!! J’acheeeeete 🙂
    Merci pour ces belles news.

    Et moi qui ai commandé un URUAV il y a qq jours…

    • SeByDocKy says:

      The UR65 is still an amazing machine. If you don’t change your Vfreq every flight, the smart audio is not necessary. The UR65 is still my favorite 1S machine 🙂

  • Rishi says:

    The specs look good, BUT if they could updgrade the vtx to be switchable with a pit mode and also, have the ability to go up to 100mW or 200mW, this would make a big difference for some of us!

    If you’re in contact with them SeByDocKy please consider requesting this?

    Also, perhaps 4 blade props should come with this as standard as they did make the original ur65 perform better!

    The only other consideration Ian that betaflight is reducing functionality for f3 flight controllers due to the increas d size of its releases, would an f4 be better, or no difference as this is only a tiny whoop and not really need the features that betaflight has removed for f3 boards?

    • SeByDocKy says:

      Yes the pit mode is a good idea… and maybe it will be already here with new AIO module. For a 100mW why not but I am afraid it will draw too much on the battery…. A good 25mW coupled with an efficient ground station solution is already not bad. You want to fly long range with such machine ? … no buzzer is here… It can be fatal :). Yes the four blades props can be a better option in practice. For the F3 limitations are for some SPracing boards… Not all (yet) are affected with… but I guess it’s a question of time. For sure… The F4 variant will come soon….and probably some 2S model as well.

      • Rishi says:

        Cheers SeByDocKy, everything you said addresses all of my questions.

        I don’t want to fly long range; I just wanted the signal strength to be as good as possible.

        I concur, the pit mode no four blade props are probably the most sensible of requests I had outlined.
