A lightweight, slim, small, metal gear, high torque, high speed servo for a low price.

Corona presents the DS 843 MG. These are an amazing servo for the price due to their ability to put out a large amount of torque with great speed. At 8mm thick and weighing in at only 8.5g, these are a fine selection for many R/C applications.

We brought these into inventory after some DS buddies told us how much they like them for small DS gliders, an application that needs good accuracy and strength.

Not impressed.

I purchased 3 of these servos to install in a Hawkie. I am not happy with their performance. Great size, torque and speed. However, they do not seem to center well at all. I noticed it on the bench when setting up the plane, then really felt it when flying. They feel very Drifty in the center. I was constantly having to adjust the trim. Maybe I just got a bad batch? It seems like others have had great luck. I don’t see myself purchasing any other Corona servos in the future. I seem to have better luck with the Emax servos.
