The G770 3D gyro uses all-new SRVS UltraLok™ technology to provide constant rotation rates regardless of head speed, wind or flight direction. And with its auto-trimming and anti-drift features, trim fiddling is a thing of the past. What’s more, the ultra high response rate 770 3D holds like no other JR gyro.

The G7703D gyro and 8900G servo are available separately or as a combo.  Either component can improve your current machine—together they'll transform it.
