RE: Will it break the sound barrier?
Thanks guys for all your input....The Zoomer is the way that I think I will go! This plane looks pretty hot! On a side note, sounds like some of you have alot of experience with the ys45....does anyone know approximate header lengths with the 9x10 or 9x9 prop mentioned above on 30%....pretty new to tuned pipe engines and just need a good starting point....Thanks again, all you guys are great!
