[NSRCA-discussion] E-Question HXT motors

Fri Sep 26 19:30:30 AKDT 2008

Anthony,

My experience with generic brand, cheaper motors has shown a lot about how
different manufacturers use various techniques to cut costs, and how it
severely reduces the quality of the product. From an economic standpoint,
it's impossible for two manufacturers to sell two supposedly identical
products at such a large price difference. The only way this is possible is
to increase the quantity sold, and I'm sure AXI sells more motors than HXT.

In performance testing both in the air and on a dyno, the generic brand
almost always under performs fairly severely. This is usually a result of
poor workmanship and poorly selected or out of date materials. There is a
large difference in the metal that comes from China, and the metal that
comes from Japan. The material costs to make an electric motor are fairly
low because they can be bought in bulk and are readily accessable. Name
brand motors tend to use quality materials, but more importantly, use higher
quality labor where much of the costs to make the motor are incurred. This
not only produces a quality motor, but unit to unit reliability.

Many people use generic motors because they boast the same (in some cases
better) numbers, for a fraction of the cost. Some end up with an up to
standard motor and end up pretty happy with their purchase. But many also
end up with a motor that performs marginal at best, or maybe not at all,
without product replacement or product support. Motors can and will fail,
and is the one component that has the capability to destroy both the ESC and
the battery in one violent 500A burst. And one way to help prevent this it
is to use a high quality system.

In the long run, you will be much happier with a name brand motor,
regardless of wether you are just getting started or have been using
electrics for years. The same goes for the batteries and ESC.
