    Application(s): Swash servos, T Rex 550. Beast X. (1257 TG Titanium gears.)

    Comments: Sport flying, loops and rolls ect. Just completed 5 seasons with no problems. One gear replaced after crash. Use them on my Rex 600 also. Excellent servo and good value.

    Application(s): Drift RC car steering

    Comments: Nothing compares to it for touring or drift car steering servo use. Great performance, durability and bang-for-buck. You'll be getting in my opinion more than what you pay for
