Very strong and powerfull, only critic is the noise.Bernard Roy

May 27, 2016Application(s): Slash 4x4, 2s vxl setup.
Comments: For the price you got the best! Instaled it today in my slash and it's a beast! You won't get its full performance unless you boost your esc bec with a cap or install a ext. Bec.
I ran it out of my vxl setup without problem but i cant waith to install my 10a. Bec to get it lightning fast!
And btw, it's kinda noisy but it's just when you try to steer parked.
You move forward a bit and the noise stops right away!RCAddict
April 30, 2015Application(s): Throttle/Brake and Steering 1/8 buggy
Comments: These servo's are known to be quite noisy at neutral but the performance is excellent. I've been using mine for 3+ years in a Losi 8ight then 8ight 2.0 buggy.
It has taken a huge amount of punishment and just keeps going strong. I have upgraded to hv servos so this will be going into an SCTE.SC-1258
April 12, 2015Application(s): RC Nitro Buggy throttle/breakes, 6V
Comments: Smooth operation, rugged housing and stiff mounting tabs, performance seems to hold true to the specifications. I've been using it for over a year without problems in temperatures from -10C - 20C (14F - 68F). I believe it is filled with Nitrogen to inhibit condensation.

July 4, 2014Application(s): Slash 4x4 + Losi 22SCT + Xray T4
Comments: Well, at first this servo did feel very awesome. But for some reason, it suddenly lost power. Happened with two different servos in two different cars. I still have this on my touring car, but in Slash 4x4 and Losi 22SCT this failed. No abuse or wet conditions, just dry surface every time. And in Losi you don't even need that much torque, because the front is pretty light, but still, all of a sudden it just stopped delivering power. Everything else works in both cars, so it's all about servo failing. Decided to switch.

Comments: Fast and strong. Steers the 4x4 with no problems. Changed the whole feel of the truck. So much better than stock.

January 7, 2014Application(s): Axial Wraith Steering
Comments: This servo is absolutely unbelievable. The .8sec transit time is no joke. The power of this servo is ridiculous. If your steering hardware got suddenly jammed, you wouldn't even know it with this unit.

Comments: Unbelievable strong servo! Very fast on 6V
In my 30cc Yak it is complete overkill :)Mike_Andrin
December 28, 2010Application(s): Aileron Servo 26%, Pilot RC, Extra 260, 30cc
Comments: Lightning fast and strong. Excellent quality. Enough torque for the ailerons, no pushback. No complaints at all after 2 months of flying. Was able to pick them up on ebay at a good price. They seem to be the same as the Align 610s. They do make more noise than other servos, after all, they are digital. These and 2 1256s are on the ailerons and elevators on my plane with 1.5 arms.
