    RE: Metal Arms for Airtronics Servos

    We recommend the reinforced heavy duty nylon arms be used whenever possible. They fit tight, have a brass ring to help prevent stripping, and are very stiff. But they still have a little give you you crash, etc. They are a favorite amongst our pattern flyers and heli flyers.

    If you need aluminum arms, I recommend the Maxx Products arms because they have a set screw that "locks" them onto the spline. These are popular with our IMAC flyers who need the big 3" arms.

    It also looks like the JR arms are compatible wiht airtronics. Horizon makes some nice one too.

    RE: Metal Arms for Airtronics Servos

    It seems to me that JR and Airtronics use the same number of 'teeth' on the splines, but the diameters are slightly different. I can't remember which, but one brand's arm will fit on both servos, while the other brand only fits one servo. Thus, I stick to Atx stuff on Airtonics servos and JR stuff on JR servos.

    The slight variances in sizes is why we recommend the Maxx Products arms. They have a "clamp" built-in, thus they grip the spline.

    I use SWB on the rudder only because they offer the 4.5" JR arm and it bolts down on the spline. So far so good, but like Mike said the MPI stuff is very good.

    RE: Metal Arms for Airtronics Servos

    I bought a 94775 and it came with a light duty arm . Will the HD arm with the gold band work on it ?

    Hi,

    Yes, the heavy-duty 2-point servo arms will work on that servo (the black ones with gold bands).

    Regards,
    Todd
