My MGT has been almost free of problems, and the tuning was extremely easy. When I go race/bash with friends there always trying to tune/prime roto-start, check plugs... Mine (stock engine) 9/10 times fires right up and kills my buddy's Savage21. Plus for whatever reason they go through plugs like it nothing!! IMO
Not to mention the layout make it WAY easy to work on, to change a spur in the savage its buried kinda... the MGT EVERYTHING is out in the open, again, just IMO...
