The A6300 is the first in an evolving line of Spektrum brushless servos that provide leading edge performance with uncompromised reliability. Boasting an extremely powerful 530 oz-in torque and a lightning fast .10 sec/60° transit time @8.4v, the A6300 will make RC enthusiasts take a second look at Spektrum Servos.

The A6300 features a top of the line brushless drive train that is recognized as being exceptionally strong and reliable. This durability is expertly matched with a low wear, all metal gear train that is virtually slop free. All housed in a heatsinking, all-aluminum case with preinstalled eyelets and grommets, which makes mounting these servos quick and easy.

The Spektrum A6300 uses these features as a foundation to produce a powerful, consistent, yet efficient servo that will prove to be in a class of its own. It is these awesome capabilities that make the A6300 a fantastic choice for giant-scale models, 3D aerobats, jets or any application where massive amounts of torques and holding power are a must.
