The conditions were cold, gusty with light winds. She powered up and flew easily out of my hand stable into a brisk gust. She climbed easily. Her frame is not very strong so she twisted out of control from time to time. I can see her wings twist on the fuse as she spins into un-commanded turns in a good wind. the wing tips flex a lot, a problem because that's where the ailerons are. In glide she is heavy, despite good CG she needs to nose down or she stalls. She also tip stalls very suddenly and hard, and takes a lot of altitude to recover, as some others have reported. She doesn't like to fly slow and she won't stay up long. I think its all because she is too heavy, and that damn aluminum spar is a big part. I think too she needs more chord. Despite all of this she was a pleasure to fly, I just spent a lot more time climbing to altitude than I did with the 2500.
I set her up with spoilerons, instead of my usual flaperons. This was really a good technique. She made her approaches floating like most gilders, even with a brisk head wind. I pulled out the spoilerons and her descent rate increased in a sweet and controlled manner. She landed flawlessly. I did stall her a couple times at altitude, not enough to recover completely, so she landed hard. No damage, pretty tough plane.
The 2500 is a big, big plane, but the price came down to about $159 at Nitroplanes... I would recommend it over this plane. I kept wishing the ASK 2100 was my Art Tech 2500.
