Application(s): Tamiya Lunchbox and DT01
Comments: Its a budget servo that performs like a beast.
Replaced an aging servo in my dt01 with one of these and was super impressed.
Its that impressive that I got another one for my lunchbox. Replacing a Savox 0251mg. Its been taking a huge beating and not one glitch. Super fast and accurate.
Can highly recommend. Will buy more for future projects.

Application(s): I use the servos in 60 size (5-7 pound, 600-850 sq inch) sport and aerobatic models.
Comments: They mount where the previously held Hitec HS425BB was without modification.
The street price is $12.95 at a popular internet supply site.
I feel entirely confident using these after 3-4 hours of bench and flight time.
I give this a 5 star rating not because of pure quality (they're very good), but because the performance for the cost is superb (value).
