I have the passenger moment, as you said, given the same size and proportioned person, it is the same as the pilot. Actually, I used two others along with me and averaged the moment to come up with the passenger station. Now, that certainly won't be the same as the artificial weight, but I will just have to do the best I can because I am not about to weigh it again with full fuel and passenger weight.
My big concern is being able to secure whatever I can find. I wish they sold small bags of something for weight that I could put in a duffle bag or something like that so it can really be secured. Let things get a little out of hand on landing and this artificial weight could cause a disaster. See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2012 - KR Gathering in Mt.
