With luck I will get the first one up and running today. The first one needed to be dished over by about 15mm, and I expect the second will be the same.
For anyone else who did not take D8veh's advice to order a spoke wrench from BMS when you order a motor: The nipples are about 3.8mm, bike shops don't stock this size, but a small adjustable spanner will work nearly as well.
