Hi, Dave,
Yes, I know that -- I have told our BOD we will
be chasing our tails for as long as we permit
electrics, but most of the BOD is wanting to
embrace the "new technology" for power...as
motors improve and batteries get stronger, things
will change. BTW, the 6s lipo is not part of the
current proposal -- we are trying to do something
different on the battery side. I will be glad to
let you know what we finally do, if you are interested...
