We've heard going on a couple years now, that the 35 was coming. Hasn't happened and may not happen.

Let me suggest you go with the OS33 GT. Terrific little mill. My first one just completed it's third year of service, some 110 hours of operation, some 60 gallons Avgas. Still on original plug, ring, bearings and CDI. Still runs like new and when I tore it apart, easyto see why. Everything was as clean as can be inside. For the record, Avgas, BelRay MC1 motorcycle racing synthetic at 50:1 ratio, 20 x 10.5 APC plastic prop, on pipe and soft mount, puts out around 23 lbs of thrust, with an amazing, very torquey midrange. It is as strong or stronger than a YS175 on 25% nitro. No maintenance in those 100+ hours....I've been RC'ing for nearly 50 years and this engine, by far, has surpassed everything else I've played with (and I've played with many many glow engines). About the only one I play with anymore it seems.
