Was flying back home to N TX from Houston yesterday and while flight following with Waco approach was given a traffic advisory. Seems a Seneca was on a converging course, co altitude and one of us would need to turn or climb. I was running against a strong headwind (standard!) at 24/2450 at 4500' indicating just under 140mph/119 Kts. The supposed overtaking Seneca overtook us finally after climbing but not by much. The surprised Twin driver asked approach what a M5 was. He said "fast bushplane."

I thought that very appropriate...

I had an M7-420 on amphibs for a while and many planes were surprised at its capability.
