Paul:  A couple of days ago Ken Powell was on a search for a lightweight
alternator.  His weights were in the 6 to 8 pound range.  I once had the
Kubata (disel tractor) alternator and the weight seemed to be in the 4 pound
range.

Ken, Might call the dealer there in LR

Yes I have heard about those Kubuto tractor alternators. Some people I
know are running them.

Im sending a photo of a Kubota tractor dyno that I just took off of my
Hummel Bird. I didn't have room under the cowling so I modified it to mount
on a pylon that hung down from the bottom of my fuslage along with a custom
made prop carved specifically for the application (my engine man did all of
the brain work and machining). It did cost me about 4 MPH in top speed.
It's a real quality set up though. It had two bearings that the shaft ran
on. I took one of them out to save some weight. It comes with a nice solid
state rectifier /regulator. It was as trouble free as could be. My new set
up will have a alternator under the cowling running off of the back of the
engine, so the Kabota has become obsolete for me now. The whole unit with
prop, regulator, fairings, spinner, and pylon weighs about 4 pounds. I can
weigh it if anyone wants an exact figure.
