Blue Bird servos

Inpulse buy haven’t used them yet.


Lite servos fast and strong

I’m using the bms 207s on a 1/6 scale 3D plane to save about 4.8 ozs they provide all the power I need and they are very fast I fly for a living and the blue birds are one of the best servers I use I love your fast service it’s one of the main reasons I use aloft hobbies


Fantastic mid priced servo

These are all metal geared servos. No plastic idler in the gear train. These are almost a perfect for flap servos or where a control might be subjected to shock loads. (I didn't see any replacement gear set to make these perfect). These have held up to my 5 minute break in just fine. They center great and have good amp resolution. I love using them at 6V to 8.4V where their speed is noted. Time will tell how well the motor will hold up to the power and speed. As these are plastic cased servos I'd not use them with gyros. (They are more than fast enough, but I'd want a metal case to act as a heat sink when using gyros)


A very good servo for mini helis

Great servo for 450 size helicopters on cyclic and also fast enough at 7.4-8.4v to be used on the tail.
