RE: Stinger II any good?
What size prop you running on the YS?
I have this on electric. Depending on how much power your looking for will really dictate your set up. The plane flies very well with a 42-60-800kv motor, 12x8 3 blade Master Aitscrew prop on a 4s 5000mah lipo. I tried this on a couple differant E props, but was not very happy.
