RE: OS IL-300 4 cyliner in line
yeeaa, multi cylinder 4 strokers are very cool, my friend runs his Magnum 160 twin on straight pipes, no mufflers, it sound so cool and it's not any louder than a 2st with a muffler,,
I would really like to have a 240 or 260 twin 4st for my ARF Gee Bee Y but I have other engines right now..
