Well my knees were knockin and I think I could have used an extra pair of shorts but my DP extra had its first flight today with absolutly NO flutter what so ever. I have one that shipped with very soft ailerons. I put in extra cross bracing, an extra servo, and extra hinges. It was rock solid. Now I know why people love bigger planes...what a joy to fly. Here are my specs for reference.

ZDZ 40 with Menz 22x8
JR 4721's all around on 6V system
Stock gear (will be replacing them...too weak)
pull pull rudder
stock horns
4-40 rods with brass tubes soldered over them for all links
4-40 ball links all around
balanced with no lead in nose

Can't wait till next weekend!
