I am new to gassers on R/C models but used to race Biplanes at Reno so we tuned the exhausts for a certain length for an rpm goal. That big, long prop with shallow pitch doesn't seem like it's much for speed, is this an acro airplane more than a speed/racing model? What are most guys looking for with this model? The long gear says acro to me.
Looks like a good flyer by that video, good looking model but not very scale to Nemesis (the horizontal is huge, probably why it flies so well).
