Ok, it seems I need to respond to a few comments. I don't ask YS or Rich for one simple reason, they won't tell you. PERIOD! If YS had a working gas engine coming soon, with the necessary cajones, they couldn't give away their current stock of glow fuel 175's, so it won't be available until the current supply of 175's were sold. Just like they do now, no 175s come out until the 170s were gone, no 170s until the 160s were sold. Unless you live in Japan, then YS will sell you whatever they have. Perhaps I have boxed myself in, so what, then I just won't fly pattern. If I don't enjoy it, I won't fly it, so again, no electric for me. And I refuse to pay the glow fuel cost, so no YS for me either unless they release a gas engine. Pattern is hardly my only R/C interest, if anything it is the passing interest, and if what I want is not going to be available, then I will find other interests. The basic question of this thread was about YS having a gas engine in development, not how stupid or short sighted I am for not flying electric, or the esoterics of whether one could be developed with the required power. It appears no gas engine is on the horizon for YS, so now I will go away and find a more suitable branch of the hobby such as classic pattern or IMAC.
