You may not know what the cg of the basic aircraft is until it is finished, but you should know the aft cg limit before it is finished. The plans for the kr2 state it is 35% mac...of course mac will vary for a kr2s or if you change the planform in any other way.
As long as the wheels are aft of the aft limit you shouldn't set it on the tail. https://sites.google.com/site/mykr2stretch/ https://sites.google.com/site/mykr2stretch/parts-for-sale On Aug 15, 2013 1:23 PM, "smwood" <smwood at md.metrocast.net> wrote: > Joe, > The main wheels have to be far enough aft so that the tail does not hit > the ground every time some one gets in or out of the airplane.
