    I've been using these for years in my yachts for rudder control and had only one fail.
    I sail in salt water and have had boats flooded, but I pack top gearbox with thick lanolin grease, add 'O' ring onto shaft, coat with liquid electrical tape (rubber compound) and they are bullet-proof. I use them in all my yachts. Great power, good centreing, tough and low power consumption.

    Bought 5 for a seagull models mxs-r, all 5 initially looked very good, however, last night the throttle servo melted down, literally, lots of smoke and melted plastic. Fortunately the airframe was on the bench and not in the air. I have read other reports of BB servos melting down, I'll be pulling the rest and bench testing them for an extended period of time.

    This bluebird BMS-621MG servo is very nice for the price. Quality seems great and speed/torque are quite good and more than adequate for on-road use like I use it. I can highly recommend this to everone.

    For the price this servo has a lot of torque and is very fast. My only complaint is it does not center well. Very good for a basher 2wd off road car steering or off road nitro throttle on a budget.

    I purchased two that run in my 1/8 scale buggy. Good torque, centers great, and noticeable quick speed. I ordered two more to replace my steering servos in my 1/10 scale nitro touring car and 1/10 electric touring car.

    Purchased 9 of these servos and 3 burned out during installation. I didn't expect to find that 30 percent of these servos were faulty
