RE: OS 2-Stroke Engine Reliability
Well Dave, I just happen to believe that a simple, easy to use bushing engine is quite often the perfect engine for a newcomer to the hobby whose time is better spent learning to fly rather than troubleshooting engine problems with absolutely no idea of what to do next.
Instructions are instructions, and are generally best if actually read. However, directions to use a "Quality fuel containing X% of oil" is a pretty open ended deal. Define "quality", and "X%" of WHAT oil? It makes a difference, and I'm amazed at the overwhelming number of rather skilled flyers in this hobby that haven't a clue about what their using. It's all about the nitro content right? Everybody knows that big nitro = good flyer. Even folks who don't know what nitro is. OK!!!!
Fortunately, there are still companies that offer fuels that meet the needs of varying engine types. Sig, Powermaster, Coopers, S&W, etc. Unless the purchaser knows what they want...it's unwise to assume the hobby dealer will steer you straight as it's unlikely that they understand the differences. Kinda sad actually. Brightly colored fuels sell better than ugly, albeit properly formulated blends. This is no small part of the reason I've been mixing my own fuel. The majority of my engines are those that prefer (and specify) that fuel contain a certain oil package, and I just challenge you to go to the LHS and buy a fuel like that. Here in the land of cheap green oil? No dice. I make my own, to my spec and I'm happy. That's me however, and I wouldn't expect others to do that unless they really wanted to.
Seems that the real emphasis is on saving paper towels, and less so with a fuel blend that will show a motor at it's best.
I shake my head......
