Rudder Servos - New 2012

Technology keeps on moving and this is true to our world of RC. New and pretty useful servos for our application are now out. A new range of waterproof servos are now available on the market. This concept is not new but what is (though still to be confirmed) is that they really are waterproof.. Below is the information about these 2 new servos.


But be aware before jumping on and ordering one - keep in mind that the size of these servos are slightly bigger then standard size servo so if you servo tray is tight check that you can increase it more first !

(1) big plus on these servos versus their non waterproof equivalent is that it can handle 7.4v ie a 2S lipo whereas the others are limited at 6v
