Here are my vented and non-vented 20th Anniversary (Limited Edition) B-Series 1.5 ***1 of only 20 made !!!*** I feel really blessed to own such beautiful Revs. I have less than 6 hrs of flight time so far - so I guess I'm getting the hang of it. Hopefully I will have the skill to fly some formations with some of the great pilots out there. Wish me luck - see ya soon !!!
