NEWS: URUAV UR65: 65mm/27g AUW/0603 motors

Remember my last SeByDocKy’award ? The excellent Happymodel Snapper6 ? A great 65mm brushless FPV racer with strong 0603/19000Kv motors and the excellent F3 Crazybee flight controller Here is new machine based on the same architecture/FC:
Same FC with a builtin FrSky D8/D16 receiver, same 250mAh LiHV batteries same 0603 motors but slightly slower (17000Kv vs 19000Kv). In the other hand the frame full nylon based is close to be 3g lighter !!!! With the battery the total weight is announced to be around 27g… It should compensate without problem the little lost in motor thrust. The Crazybee FC is a great board with builtin 5A ESC, builtin receiver in SPI mode (FrSky or FlySkyà, super stable even in angle mode. The AIO module is the same than the Snapper6, based on a 700TVL NTSC CMOS camera + 48CH/25mW VTX. At least for the FrSky version, the machine displays the RSSI for the OSD but also export it via telemetry. More it also includes a current sensor. The machine is proposed with two type of bundle: a standard with one unique battery or with three batteries and a charger. I can image how sporty can be this machine with the Happymodel 0603/19000Kv motors (some 22000Kv from racerstar are also announced).
Wait & See.

  • indy says:

    and let’s see if the flight time is slightly better… and if the rigid frame makes a difference as suggest Albert Kim in YT…

    • dudu du76 says:

      Albert was saying that about the 75mm frame.
      But, not sure this is still true on 65mm one.
      I tend to think that the BetaFPV65 Pro frame is rigid enough for 65mm

      • SeByDocKy says:

        I will publish the review of the UR64 in a couple of hours…. I am very impressed by this machine. I crashed it many time… No big stress observed on the frame…

  • Lorenzo Rigamonti says:

    Hi sebydocky,
    I bought one of these ur65 but i have strong jello in the video feed…all motors seem to spin freely and it has jello also with the spare set of props, so not unbalanced props. Did you notice jello on yours?

    • SeByDocKy says:

      A bit some. 1) check that the heatskrink tube jailing the three moto’s wire are not in contact of the rotating bell part of the brushless motor. 2) you can swapp props for some more 4 blades better equlibrated.
