Can't get enough of these servos. This one was for a Turnigy Trooper SCT truck. It has more than enough pull for 1/10th scale and these seem to last me forever. I've had a couple wear out the sensor around the neutral range but this is after several years of abuse so I'll keep buying them!I just started to use two of them, but they are really great. Fastert than the Turnigy™ TGY-4409MD. Sound is good, and so precise.Fantastic! Have these fitted to both 1/10 scale buggies and they perform superbly. They are fast, strong and easy to install. Recommend.Bought it. Set it up in a HobbyKing Smash Shark Boat. Drove it about 3x 20min (in 3 days) - at the fourth time the motor inside broke (BAD smell) and I almost lost my boat... Not at all recommended. PLEASE TAKE MY ADVICE - buy one with brushless motor inside!!!!!!!!!nice servo for my rally project1 word...
Ok ok.. Cheap, fast and strong. Forget the expensive brands.. BlueBird is the brand you want!A really fantastic servo for a buggy, or any other type of RC car. I had previously been using the TGY-4409 servos, but figured I'd give this one a shot. I'll never buy another 4409 again...this blows it out of the water in every category. It centers much better, and it's so much faster, I question the rating system HK is using. Either the 4409 is WAY overrated on speed, or this one is way underrated. The difference is night and day, even though they are only .01 seconds different in speed. I can't comment on durability or longevity yet, as I have only been using it a few weeks, but so far, this is an excellent servo at a budget price. I'll be buying more of them.I used this servo to replace HSP 1:8 Nokier monster truck original servo that stripped gears.
So far it looks very good. Fast and strong. Definitely faster than original was.
Also accessories pack is nice. Servo arms are reinforced with aluminium ring around splined part. So it is less likely to strip splines on servo arm.
I will order some more for other cars.Ich habe diese Servos in einer Liberty Sport. Sie arbeiten so wie man es erwartet. bin sehr zufriedenStrong easy to install servo. Cheap compared to others that are the same speed and size.. Ordered three of them for all my cars
