The plane is plans built. (No the plans are not scaled at 100%.) You can both widen it (Mine is 3 inches wider) and heighten it (Mine will be 2 inches higher). This means that the plane will be a little bit heavier and the preformed parts that can speed up the construction won't fit. However, the wings can be lengthened/modifies (winglets etc.) and the canopy changed with the same ease of the plans construction.
One person built a KR2 up to handle an IO-360 engine with a 26? ft wing spread. Its basic weight was right at the GW for a normal KR2S. Unlike the RV, or any of the kit,series of planes, the KR2 can be anything you wish. Larry Severson Fountain Valley, CA 92708 (714) 968-9852 lar...@socal.rr.com
