Re: KR> Stall speed

Yes N886MJ has the AS5046 airfoil. I was at the beginning stage of building the wing when the new airfoil emerged. I had already built all spars and that is why I used the AS5046. On my new project I am using the AS5048 airfoil. Mark Jones Oldsmar, Fl N771MJ “WunderBird” www.flykr2s.com flyk.

Before I get corrected by a bunch of people, IAS stall speed remains the same regardless of altitude. Not sure what I was thinking when I wrote that. Right after I sent that I thought "I wonder why I never thought of that before". It occurred to me when I woke up at 1AM and something was nag

KR> Stall speed

Mark Yes it lowers the stall speed due to the reduced drag of the aircraft in ground effect as compared to a measured stall speed in flight say at 2000'. I stand corrected if someone finds it in print from a reputable source but I don't believe there is a set amount. It has a great deal to do wi

KR> stall speed

Stall speeds have been confirmed now at 69 mph power on, 71 mph power off, with or without speed brake. It is my contention (opinion) that since the speed brake does not effect the stall speeds, it is not producing significant lift, or the stall speeds should reduce reflecting the additional lift
