The Mark II’s 417-shp Rolls-Royce engine is mounted with a direct-flow intake at the front of the engine. The Rolls-Royce powerplant and Soloy-built gearbox weighs just 190 pounds—much less than the stock 206 engines. That meant Soloy had to come up with an engine mount that put the turboprop engine and gearbox farther forward (below). The STC comes with the cowling, mounts, engine controls, and instruments, plus polished stainless steel exhaust stacks (below right). The Mark II is a flying SUV that can take big loads into small, unimproved strips, making trips to those remote vacation spots with short runways a breeze. AOPA PILOT • T–7 • SEPTEMBER 2011
