Default RE: Hitec 82 MG servo problems


ORIGINAL: littlephoenix wondering why people pay so much for hitec's when there are servos that out perform them and much cheaper,,,,any ideas?
Performance and Reliability backed by Acclaimed Service - a few of the reasons Hitec enjoythe greater popularity overall.

Metal gearservos wear out faster than nylon/karbonite gears and cost more to manufacture.
The cheaper servos use cheaper motors(which cause many BEC/Brownout problems) and do not have long lasting pots. All Hitec cored servo motors use incredibly strong Neodymium rare earth magnets, also known as “supermagnets”,.
Cheaper "MG"servoswith molded (compressed metal particles)alloy gears usually have a very light short lived hardening coat, not to mention the typical gear assembly of cheaper units, including some sold under rebadged "USABrand names", for example:

In the “servo world” you get what you pay for.
