MT62
The MT62 is the most bang for the buck in the line up. It is piston port induction, with electronic ignition. I comes with a muffler and stand-offs. You can use 22x8 to 24x8 props, I personly like the 23A Xoar prop on my MT62 in a SD 260 Extra.

This engine is a great replacement for that old magneto G-62 in a scale plane, no need for spring or electric starters.
