Review – Blue bird servos BMS630MG – BMS610MG – BMS617MG – BMS660MG
I know Blue Bird servo for more than a year and I raced with one of their servos in Monster GT last season. I read many comments on many different forums, some were negative but many were positive. I finally ordered one. At first I was sceptic about their quality due to their low prices, but after all the abuses of monster trucks racing, I had to changed my mind. The servo still working perfectly.
Blue Bird 630MG Servo
Like stated previously, I raced my Monster GT a complete season with the model 630MG as a steering servo. The servo has enough torque to completely steers the big Monster GT’s wheels from full right to full left while the truck is stand still. This is always nice to have a lot of torque. The servo’s speed was correct. Not extremely fast but not extremely slow neither. In fact. The 630MG is fast enough for everyone who races or bashes. The servo’s gears are metal and they seem to be very durable. With all the abuses I gave to this servo, I can’t imagine a better long term test. This servo is strong and I never regretted my purchase.
Blue Bird BMS610MG Servo
I dropped the BMS610MG into my Team Associated RC10B4. I was surprised by how the BMS610MG steers perfectly my B4. The steering was quicker and more precise that my former steering servo (which is made by a well known company and is also 2 times much expensive). The BMS610MG fits perfectly into the restricted servo location of my B4.
The BMS610MG gave to my B4 a fast and precise steering with enough torque to go everywhere, on any track and against anyone. It’s a perfect match for any 1/10 scale trucks, cars or buggies. They can also be used as a throttle/brake servo on monster trucks, truggies or 1/8 buggies.
Blue Bird BMS617MG Servo
For BMS617MG servo, I decided to test it in my old Team Associated RC10GT as a steering servo. Once again the servo also fits perfectly and has no problem to steer the GT’s front wheels and to keep them pointed in the right direction. The servo responds quickly to all my steering inputs in any situation with great precision. With 110oz of torque and a transit time of 0.09sec, this servo is a perfect choice for my RC10GT !
Just like the BMS-610MG servo, the 617MG can find home in any 1/10 scale cars or trucks or just in any 1/8 scale vehicle as a throttle/brake servo.
Blue Bird BMS660MG Servo
The best place suited to test a high torque servo is a monster truck, so I decided to install the BMS660MG into my Monster GT equipped with the huge stock tires. Even with those big tires, the BMS660MG has enough torque (195oz) to easily steer front wheels left/right in any situation, even from stand still. The BMS660MG uses 2 heat sinks to keep everything cool under heavy use. This make the servo a little bit longer than normal servos.
All those servos are all metal gears, with Futaba style splines and Hitec universal
style connector. So you can use Blue Bird servos everywhere you want. They all come with heat sink to dissipate heat. The cases are made of resistant semi transparent plastic and are all
During all the tests, I never had the feeling of driving my trucks with low quality servos. I’m sure I can borrow the transmitter to someone else and he will never know he were driving Blue bird’s servos. No sign of premature wear after many runs.
No matter you are a racer or a basher, Blue bird servos are an excellent way to get great quality servos at affordable prices. In fact, Blue bird servos are at least 50% less expensive than any other brands for similar performance. If you are on the budget, those servos could be a nice opportunity for you.
