Default OS FL .70

Why does almost everyone talk bad about the OS FL .70? I have one in GUMBY & he has around 30 flights under his belt this season in a H9 Cub with no problems at all. Good Idle - No Problems.
Just asking.

I think most of the problems exsisit with inverted running/airbleed carb and the first gallon of gas. When i got mine i expected it to run like a top after the first gallon while inverted. Now i realize that as i kept running it i got better every flight.

The FL70 performs as OS intended it to.

People expect it to perform like the 70 Surpass or Ultimate. It doesn't match them in power.

just the price difference alone should be indicative of the performance of the FL vs. the Surpass. after a club member help set up my FL (on a cub) it runs flawlessly. i would never place this engine on a plane designed for high performance.
