    Nice Aluminium Arms for your Discovery

    They are 50mm longer than DJI arms and weight per mm is the same.

    too expensive for what it is

    wrote him an e-mail and had a quick call with him. I agree, they're expensive at the moment. will definitely need to look into this with him.

    Hi Guys, just a thought because they are 50mm longer how would things improve if they were used only for the rear of the Discovery. This would improve battery weight carrying capacity and perhaps eliminate or reduce the problems associated with fast Yaw when the disco is hovering (stationery).
    Trappy you are the engineer what are your thoughts.
    Thanks and regards - bruce

    it should definitely improve the yaw. not sure about pitch though. the CG spot would certainly change... might require a lighter battery.

    Nice Aluminium Arms for your Discovery

    Not to be a downer or anything, but wasn't one of the original design assumption that the plastic arms were designed failure point in the event of a crash, so that less of the force would be transferred to plates? Wouldn't these arms place more stress on the expensive bits in the event of an "unscheduled aircraft/ground event"? Maybe I'm the only one that wrecks quads around here.
    Shut up and fly.

    no, not at all. this is obviously something you'd need to take into account. this removes the "point of failure". aluminum bends and doesn't break, which can do devestating things to the rest of your frame. however, I guess what people are hoping for is better flight characteristics. as with everything ... it's a tradeoff

    I'm still waiting on a reply from the guy. last I heard was he needs to talk this over with Tim from RMRC, which probably means this will not play out well for TBS or the designer

    Aluminum is horrible material for transmission of vibrations...
    When nothing else out there will suit your needs... design and build it yourself.
