  • Hobbywing flyfun V5 error beeps with Jetfan

    Hi all,

    Scratching my head on this one. Flew three flights today on my new power setup in my Freewing F-14 and all ended up the same: double-beep error code after a stutter of one of the edfs airborne. The manual says it is likely a temperature control issue, but it’s a twin edf and the other side has identical cooling and does not do it. I have confirmed with the programming card that both escs are setup identically. All default settings except I selected 0 degrees timing witch the HET motors recommend.

    Here is the setup-

    Freewing F-14 twin 80mm
    Jetfan 80 V3 fans
    HET 700-68-2250kv motors
    Hobbywing Flyfun V5 120a ESCs with red power wire pulled from throttle leads for standalone UBEC
    5000mah 55C SMC 6S batteries

    Anything I can do on the bench to find the culprit?
Working...
