You're in NE? What do you ever do outside anyway this time of year? Nitro and FL go well together.
I don't know why some people say modern nitro engines wear out. Unless you lean it out, abuse it in a crash, let it rust without after run maintenance, get sand and dirt run through it, they should out live us. I have Enya and Tigre engines from childhood that still run like new and doesn't everyone have 100 hours at least on their club trainer? Nitro engines owe you nothing when you retire them.
