What are your Dp extra weighing?
I have the 2nd generation kit. It has a DA 50 in it, and it weighs 15.5 lbs. Wing loading is 29.2 oz/sqft, which is perfectly acceptable. Slows down for landing just fine.
I saved a little weight by adding graphtech carbon fiber gear. I would NOT recommend it.....the first gear delaminated and had to be replaced. The second has stayed together so far but makes the plane VERY bouncy on landing (compared to the stock gear.)
