I don't really know what else to say about it... I thought it was pretty thoroghly covered layman-wise (if that's a word... it ain't... lol)
I can get real technical with the inner workings of a computer... or how a wheelchair motor or controller works... but unless people want to ask specifics about the engine swap that I can relate with the experiance of observing what went on, I didn't do too much hands on stuff except to guide the mech on the info I've gleened from here and other sources on the net as to what would work and what might not.
Give me a list of specifics you would want to know and I'll do my best to document it all out.
