I received the following question from a fellow local eboard builder on my old site.
My response to this is not an incredibly learned one, but here goes:
As you said, ideal motor placement is highly debatable and is a matter of preference. In fact, I made an ‘error’ with the welding and mine ended up toe side-rear. I got advice from fellow builders here: http://www.electric-skateboard…
The rationale would be for a regular rider that the most weight would be on that part of the deck and truck (heel side-rear), thus better traction I guess.
