Thanks for the excellent job on your Pitts build up! Just got mine on Friday after a 8 week wait. According to the importer it's the only one in Australia at this time . Am putting an Air Hobbies 4.6 twin in mine. Do you think this will be enough power (i'm power mad!) or should i go bigger! Have followed your article /review from the beginning and can't wait to get mine in the air. Any tips, other than what have been covered here for me before i begin assembly?
