January 13, 2017Application(s): Wing servo for a 2.5m composite glider
Comments: There servos have terrible centering and I would not use them again. I have now switched to digital servos with good centering.

January 13, 2012Application(s): Fast moulded gliders
Comments: These are very good, highly reliable servos. They are thin, but fairly large in other dimensions, and quite heavy. They make great servos for very thin wings in high performance planes. The metal gears are very reliable and resistant to stripping. I have crashed them many times and they have never stripped, never failed in any way. They seem more reliable and more resistant to stripping than the digital versions (5125s). Highly recommended. However if you can fit thicker servos in the wing then you could consider something like the even tougher Hitec HS-85mgs.
