I love my avistar, it was my 5th plane, it is a great flyer and slows down nicely for landing, i'm running a TT PRO.36 with a 11x5 APC prop, i think the RTF version comes with a OS .46LA, this should be a good setup and i will suggest a 11x5 prop on that engine. My first engine was a OS .40LA and like i said in my second post to you all i had for field equipment was an old 12" broomhandle a dubro glow ignitor and a manual fuel pump mounted on my jug. I don't think you'll be disappointed.
