Quite correct about the Evolution! Thanks.<div>
<div>I disagree to some extent about the nitro content, but I'm very open to hearing other's experience here. Many people do use 0 to 5% nitro, as I do in one plane I have with a Rossi. But I don't think a beginner should start there. Since this article is aimed at beginners who are most likely starting out with an entry level engine like an 0.S. or Magnum (especially if I'm training them and they are taking my advice) I think 10% to 15% Nitro content is more user friendly when it comes to tuning for a beginner. Agree or disagree?</div></div><div></div><div>As for the glow plugs, I have sort of the same opinion. I didn't address 4 strokes in this article, but I do use O.S -F or Fox glow plugs in them.</div><div></div><div>However, In my two strokes, I do use #8 in the summer in most of my planes, they serve me longer than the A3's. But I find that tuning is a little more finicke using the colder plugs. So for beginners, I usually have them use an A3. Agree or Disagree ?</div>
