Mac,
I am fairly sure that it is not legal to fly the plane in a configuration in which it has not been tested. That said, be sure of your CG. When I had my first KR with at 1915 engine, all I could hope to carry was myself at 170# ( at that time ) and 120# of concrete block. I agree about the sand bags, but you can secure them to your seat belt system, or make you a sand man and secure it, or something, so you can test it a little at a time. Oh, and with the 120#, it got very, and I mean very, squirrely and with low fuel, it was even worse. Also, make sure you don't have any obstacles to clear until you have plenty of room to climb and make sure your brother knows what he is letting himself in for. This is not a flame, just a word of caution. See you in Mt. Vernon - 2005 - KR Gathering See N64KR at http://KR-Builder.org - Then click on the pics There is a time for building and a time for FLYING and the time for building has expired. Daniel R.
