REFLECTOR: Franklin Alternator

[Michael Watson]

Larry,

I'm really not that close. Flying alone, and with 75 lbs. in three leather
bags of
shotgun lead (25 lbs each) under the co-pilot seat, my cg is *119.5*. My
airframe
was built very light, the problem is the weight of the Franklin engine and
accessories
back there. It's a good thing that the IVO prop is very light.

Yesterday, I replaced my concord battery with a Odyssey PC 1200 mj so that
added 4 lbs to the arm at 28 inches. The Odyssey spun the engine so fast I
thought it was idling.
