Thanks. Don't know about South travel.

Knocking about is like a smooth 2 stroke should be, with a balanced propellor. There is an 'airframe resonance' at about 3300 rpm where things get to buzzin' and hammerin' pretty good, and lots of noise at that setting... above or below, it really is very smooth.

Don't know if it will last, nor how long. It's all experimental, just like every aspect of the game.

The ignition is slightly different between the Evolution and the MVVS. Dual magnets on hub on MVVS, supposedly "reset" magnet for each pulse in their Vlach Ignition. Don't know that for sure. No clue about what is really going on; maybe Dick Hanson could shed light.

The MVVS really is very strong and solid.
