Firstly, does anyone know if the JR DS171 in the UK is the same as the JR368?

If so, how are people getting on with these servos? Any issues? Do they live up to their pretty impressive specs?

The Hitec 125, 5125 are not allowed in my club on flight surfaces due to previous reports and experience of gears stripping. Am I correct in thinking that the 171/368 gears are stronger? Any reports of stripping gears with these servos?

I am looking at putting them on elevators (and possibly ailerons) of Wren 44 powered Comp ARF Spark.

Thanks
