finally got to run my H.E.S full monty mantra yesterday, runs like my old murnan btt motor with a bit more bottom to mid(probably due to it being larger displacement than most .21s). two tanks in I was running 8 mins a tank with some fuel left. I did run it for a couple laps in edmonton the previous weekend but didnt loctite the engine mounts and ate the clutchbell up in warmup so it never really warmed up fully.
