I had my maiden flight today! I have a Evolution Trainer Power System with a OS #8 Glow Plug. The engine will not run reliably at a low idle do I need a hotter plug like a #6? I was flying in the evening around 5:30 and I flew directly into the sun and my engine quit so I had to land without any power. That happened one other time so I had two dead sticks. The engine is swinging a top flite 11x6 power point propeller. Is it just a coincidence my engine quits when I fly into the sun?
