the story i got (second hand) was the owner of skyshark r/c had re-engineered the eagle to be more "user friendly". in doing that the bottom wing and stab incidence was set to 0 degrees and the top wing was set to +1 degree (all compared against the fuse side) the positive wing incidence, i gathered, was more or less to act as a full wing flaperon in creating lift and drag making the plane come in slower and less likely to stall.
Was that first landing into a really healthy head wind? It appeared very steep, but controlled with a non-existant roll out
head wind was around 5 to 7 mph. and th eplane did float in beautifully. tracked straight all the way to the ground. pilot said he brought it in for final at 2 or 3 clicks above idle. and chopped it when the plane was 3 feet off the runway. once the mains set down elevator was SLOWLY pulled all the way back.
