Includes 1 review aggregated from around the web.
There are very few reviews for this servo on the web. One owner flying it in two 450-size helicopters and a couple of foamy planes reports no problems caused by the servo and says it is the best bang for the buck. He used it as a cheap replacement for Align servos after a cyclic servo failed, and could not tell much difference in feel. Other forum posters say Corona servos are liked by many, but those comments are secondhand.
