I just purchased a bunch of these motors thinking they would make suitable
spec-motors for a student-designed car race. I was thinking of doing
something similar to what PITSCO does with their CO2 dragsters...
Unfortunately, there was quite a bit of variance in the amount of power
these things produced, which would make racing them unfair. Now I'm not
expecting swiss-movement precision here, but I was hoping for something
better than I got - for example, one motor sent the model flying 50 feet
down our shop floor (and it would have gone even farther had it not hit
something), while another struggled to make it 15 feet. Maybe I just got
some bad apples?
These are the same motors that come in the non-Technic dragster sets 6616
and 6714. I have one example of each of those, and their power is more
similar (i.e. they're both quite strong). A colleague of mine suggested that
the age range of the toy might have something to do with the strengths of
the motors, but I'm not too sure about that (the Technic kit's age range
actually starts younger).
I think the more plausible explanation for the variance is the 5223 kits are
probably made up of spare parts LEGO wants to get rid of, and they figure no
one would notice if one or two were down on horsepower (except crazy
teachers who want to race them).
