These servos are amazing. They are strong, robust, and center very well. I use them as elevator servos on my 50cc planes.

Used these servos on a 50cc yak54. They performed well but one of five servos started jittering only after 6 flights. I contacted Blue Bird Technologies Ltd. and they are going to repair the servo under warranty. If it were not for this small problem I would rate 5 crowns all around. I use other Blue Bird servos in giant scale planes and have had great success.

Ok guys I ordered over 6 pcs of these servos for testing purposes and to install in my planes. All 6 were tested under extreme pull stress starting from 8kg/cm to 17kg/cm at 7.4V. The servos easily reach 16.0kg/cm without any problems.

I tested electronics and all was well-made. The gears are good and smooth. Overall, the quality of these servos are Good for those who need 17kg/cm performance.
