Finally got a chance to maiden my DP Extra 330 ARC / BME 50 ARC yesterday. Plane came in at 16 lbs 1 oz ready to fly dry. It was sixty degrees here in CT with a 10 - 15 mph wind. Prop was a Menz 20 x 10s. I was a little concerned about the weight but quickly realized it was absolutely not an issue at all. The plane tracked straight, lifted off smoothly and after only a couple of clicks of trim flew flawlessly. Slow flight was unbelievable! Landing even better. Has a slight bit of coupling in knife edge as I expected it to but otherwise no bad tendencies. This could be my favorite plane to date!
I never did get the engine dialed in quite right (I was on the rich side on low and mid) but the power was WAY more than enough. Could pull vertical, let airplane stop and then pull out with authority at half throttle. Got in two flights but thought I saw some aileron flutter on a low speed pass on the third so brought her in to check everything. Not sure if it was flutter or just vibration due to rich low end. Am using Horizon aluminum arms, Horizon titanium rods, and rocket city balls all around. Gaps are sealed. I do not know whether the JR 8101's are enough on the ailerons. In any case, will spend a little more time setting up engine and hopefully have this one around a long time!
I would definitely recommend this plane to anyone. I am certainly happy with it and don't let the weight scare you. The BME 50 is more than it needs and I may even try swapping my 44 in to shave a few ounces off. I guess it is time to start assembling the H9 Cap. If JBH is right (and I assume he is) then I will have a new favorite airplane soon. LEt me know if I can answer any specific questions. Have fun, cbk
