BMS-820DMG+HS High Performance Digital Servo (Metal Gear) 9.2kg / .09sec / 45gWith an integral heat-sink, these servos are designed for the demands of competition racing, keeping the motor cool even when the outside temperature is hot and the servo is being overused. With a heavy duty rubber-sealed waterproof case and high-strength horn set, this servo is perfect for high-performance R/C car applications. And the output splines are compatible with aftermarket 25 tooth Futaba horns.
The servo will automatically learn the user''s transmitter pulse timings and lock into the signal every time. The servo also includes a signal buffer in the CPU with fail-safe functionality. The motor is wound with 2PEW thin coated wire for better electrical conductivity and is able to withstand high temperature without degradation.
The servo comes with an accessory package and the universal JR/Hitec "S" Connector which is physically and electrically compatible with all major receiver brands sold worldwide.1. All Metal Gear

These high performance servos are very strong and have a coreless high torque motor that requires a STRONG power source. Many ESC''s inbuilt BEC cannot handle such current, and will shut down the Rx.
We advise customers to use an external UBEC when using this servo.

I think it is a very good servo but it seem slower than 0.09I use this Servo in a Team Magic E4JS and is a Great Servo. The Price is TOP !A sport flier, these are excellent! No technical test, but, they fly great and none have failed and I use them on 3 (three) 550Es and my new 700E. Hey, the price and performance, I cant find a reason not to use them.these servos seems to be well made. its quick. ideal application would be throttle/brake function in a 1/8 scale nitro truggy, buggy or monster truckWill be used in WIND S as rudder. Fast and strong. I put one in a Axial Wraith rock racer works well , strong servo looks well build ,steers / tracks great !
steering is faster and sharper .i got 2 of these puppys sweet deal 2 high performance W/P servos for the price of half some leading well known servos brands ,This servo is the tits. I tell it to move slowly and smoothly and it does it. Then I tell it to move its ass im in a hurry and it does it without thinking twice. Its strong and it doesnt f*ck around. Top quality.Very strong and fast.Im using these on a 1/5 scale 3d plane and they are very fast on 6v. They also center very well which is important to me. Great servo for the money.I found this servo to be quite solid and quick but must be supplied with good power. If you are using this servo for a gas buggy I would recomend the use of Lipo with 6v regulator. Testing so far is working well with Lipos but have some issues with NiMH but at this point need to test with a diff NiMH pack to eliminate the pack as the issue.
