Hey Steve, I wanted to go a little bigger on the prop but our field isnt "perfect" if you know what I mean & with out putting monster tires on this thing props wont last long. On 40 size planes & up we have no problem. You are right this little rocket tumbles at almost no effort and spins are a bluuuuuur & whats great about it is for a plane this agile & small I have had NO problems getting it to recover from anything - yet -. I havent tried a flat spin & dont know if I should. I am a little nose heavy so it might come out of one. Have you tried it?
Also I like the tag in your pic! I to am from NC Where are you located? I'm in the small town of Clyde just west of Asheville.
