Re: shaft drive
I love this idea , an have tossed it around myself , just remember you may have to make everything , a scavenged shaft from a small motorcycle may not be the best choice these motors do not produce a lot of power so the rotational weight of a scavenged shaft may be too heavy ,but said shaft could be the easiest way to reverse engineer a smaller version . good luck I hope you succede!
