For those of you new to the group and interested in propulsion, check
out this webpage which is a tutorial on how hybrid motors work:

Also, if you are new to the group and interested in propulsion, reply
to this email and I'll send you a copy of the instruction manual to
our hybrid motor, so that you can become familiar with it before our
hybrid basics workshop.
