If it is still legal (see
Nate's question posted elsewhere) then a modified Globe gearmotor might suit your needs. The modification involves disassembling the gearhead from the motor, removing all the gears, cutting the gearcase to a reduced length, then reassembling two of the three planetary gear stages in the shortened case and putting it back on the motor. The modified Globe then spins at a nice speed for harvesting. Search old threads
here for details of the modification.
However, as Nate pointed out, the 2009 Game Manual might not allow this modification.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
