Hi Ralph, The empty CG is not relevant. The CG of the plane when loaded is the issue.
If you have a header fuel tank then you want to be right on the forward limit with minimum pilot weight, no baggage and a full tank of fuel, the CG will move back as you burn fuel off. On the other hand if you have wing tanks then you want to be right on the forward limit with minimum pilot weight, no baggage and a minimum fuel in the tank, the CG will move forward as you burn fuel off. Having the CG as forward as possible will give you the CG range to be able to take passengers and baggage without using the last 2" of the CG. See my weight and balance info at http://www.users.bigpond.com/kr2/w_and_b.htm Regards Barry Kruyssen Cairns, Australia k...@bigpond.com http://www.users.bigpond.com/kr2/kr2.htm -----Original Message----- Netters One more weight and balance question. Where should the CG be on an empty airplane? My KR2 plans say the CG envelope is 4" ahead of the aft side of the front spar to 4" behind it.By moving my battery and ELT as far back in the tail as I can, I come out right at the forward CG. When I load it up with pilot, passenger, full fuel in the header and wing tanks and 15 lbs. of luggage I only move it back 3.4 ". This is still in the front half of the envelope. I do not want to use the back 2" of the envelope, but this seems a little far forward. Where is the normal starting point, and how much does it usually change from empty to full? I appreciate any help I can get. Ralph Snyder Burbank, CA ralphnd...@sbcglobal.net
