Thanks a lot Remi.
"Definitely"? Does that make the 380 a late planer?
Do you have an idea about the differences in numbers. Lets say I can pump my formula on a plane in 9-10 knots of wind. When will the 320 and 380 then start planing.
What about the cruising speed of the Phantom in less than 8 knots (where the formula is dead boring ;-).
