MS500i vs MS462 vs 572xp vs PS7910 (all stock)

The new fuel injected (first ever) MS500i has some impressive stats on paper, 6.8hp/5kw with 79.2cc by only 6.2kg/13.6lbs powerhead weight. A lightweight powerhouse! I wanted to see how the saw keeps up against some comparable contenders. (Also, check out my test against some ported saw's. ) Now it's finally time to squeeze a bit more out of the 500i ;)
