Britbrat, Patch's planes are four years old and still flyable 'cuz he's too CHICKEN to come mix it up with the Detroit Demolition crew at the RCCD meets! c'mon Patch, we miss you and look forward to cutting your streamers and maybe giving you incentiv to build some newer planes!!!

All joking aside, RSN is indeed a very durable covering method and we also have planes that are several seasons old and still going strong. It's hard to beat for durability, though it has a few drawbacks too.
