this the link for xpert servo. I have savox 1258, 1256 and 2274 as well. 2274 is the best by far. Here are specs for each above. Savox brushless servos was 20 dollars more expensive about 2 months ago or so. They dropped the price and amain changed discount policy. Therefore, i was able to buy 2274 for 83 dollars instead of 110 dollars. Highly recommended servo which TY tessmann uses. 1258 is fast servo but you dont wanna put 12kg torque servo in your +3000gr rc car. 1267 is one of the most preffered servo for 1/8 scale models. I suggest it if you have an esc supports 7.4v or an external bec. Also, 2274 is an brushless servo which has longer life cycle and draw less amp compared to coreless motor.
