Magnum Engines XL 70 RFS Blue R/C 4-Stroke Engine (11cc)
- Product Review (submitted on September 22, 2011):
- I have a Magnum 70 on my Hanger 9 Cub that seems to like a new glow plug every flying session. Symptom of when it's time to change plugs is the engine idle drops significantly when the glow ignitor is removed and the engine runs irratically at anything below half throttle. A new glow plug, using both the O.S. type F and the Thunderbolt, solves the problem. Performance is great with the new plug - for awhile. I'm spending as much on glow plugs as I am on fuel. Other than that, it's a great engine with good power and smooth transition.
