  • Sonix 3dx 450 servo problems. HELP

    Hi, After a recent crash and stripped gears to the cyclic servo, i have purchased a set of Acer Lab D12-MG to replace the existing only to find they are to deep to fit and the rear servo binds on the belt pully. I am now worried as to which to buy as replacements ( dont want the same problem) the damaged ones are cheep tower pro and measure 18 mm from the front of the mounting plate to the rear of the casing where the A-L measure 22mm.

    Any sugestions welcome but I am on a budget, something better than the Tower Pro.
    All the best STEVE.

    I used 65mg's on my 3dx, but they were very tight and hardly "budget"! They worked flawlessly and never stripped (though one has randomly just died now ).

      Are you sure you can't do a bit of filing and make them fit? or mount them underneath instead of ontop?
      Send me some pics Steve.
