| -5- The strength will be more evenly distributed over the length of the frame, and the total weight will be slightly less, 250 lbs. The drilling projected on the original .104 Bentley III frame should be applicable to this frame, which should reduce its weight to about 225 lbs, the stiffness then being equal to the existing Wraith.
