  Mike Chervenak's approach to model building is as simple as it is unique. The entire hull is shaped from foam surrounding a plywood frame covered with a bonded ply skin. This technique has its advantages over the usual frame and stringer model boat construction. First, it is faster. The deck will be free of unsightly and troublesome wrinkles, and the bottom lines will be "true" — extremely critical in a hydroplane. Although only slightly lighter in weight than its framed counterpart, the foam shell withstands any assault by an overzealous competitor quite well. Repairs are fast and it won't sink. An attractive feature is the complete concealment of the engine under the cowling.

   In 1974, the U-95 made its debut and became, at once, both the first successful turbine powered Unlimited in history and a scale modeler's delight. Attracted by the clean lines and space-age appeal of the 28-foot hydroplane, Mike Chervenak scaled his R/C from original hull drawings. Mike, a professional modeler, points out that it isn't actually "true" scale since minor modifications to the bottom allowed for engine mounting at an optimum shaft angle, and set the boat up for circle competition.

   Designed by Ron Jones — the current dominating Unlimited hull architect — the futuristic speedster was lofted to accommodate twin Lycoming T-53 axial flow turboshaft engines. The T-53 had gained fame powering the Bell Huey helicopter used in Vietnam as a tactical transport. Originally rated at 700 H.P. each, continual factory modifications boosted the output to 1,400 H.P. A sophisticated gear box, regarded as a design masterpiece, coupled the turbine to a single propeller.
