Mike absolutely right, anywhere between 15 ft altitude and zero, the visual cues are all you need. However it's the earlier stages from base leg to late finals where AoA is more useful and ASI is les

That's why I took em off. Wish I hadn't now :-( Graham incidentally that's another story, very careful attention to the leading edge profile (digital airfoil section as Don designed) make an enormous

Hi Ron The essential thing is that the nose radius is quite small, therefore VERY easily sanded away, it is also as you say drooped a bit. The effect is very subtle and not obvious to the unaided eye

William yes it is correct, BUT, they need to be the same at two thirds span, ie roughly where the flap ends. Any difference here or further out will cause a roll bias. So, check the second wing at th

Greg The neatest float gauge is the one Europa used to sell, It has a magnet attached to a cork and reed switches at 8 or 10 points to read level. Very reliable. Best advantage of capacitance is if t

The first stand alone gauge of this type was installed by Graham Clarke in the earl;y days. He used an old ASI to sense the head. Tricky to engineer but it did work. Our PFA weren't happy but Graham

Mark (imho of course) If your SmartASS was couple to AoA it would be even better because it would keep you on the correct speed. AoA is predictive, ASI is "postdictive " if you see what I mean Graham

Europa factory tried 30degrees on a mono wheel and found that the airplane would lift off too early, (ground effect) so you end up flying without aileron control. That's why 27 is considered the max

Ron Thanks for the X-Plane data Ron, I must install my copy and learn to use it! Steep learning curve I fear :-( increased flap deflection would therefore reduce the flap limiting speed too. Graham

Steve just use a 6 inch length of draft proofing foam, it's called a Gurney flap. Decide which aileron needs to be deflected up, put the foam under the trailing edge and test fly. If that isn't enoug

Steve anything will work, just needs to deflect the boundary layer a little, 1/4" wide stuff will do it. It is a neater solution because it doesn't show unless you look under the wing :-) Graham

Rowland do not go for an engineering bearing fit with the Tufnol. I once took of after a cold night (in the hangar) and the weather had warmed up a lot. The metal parts expanded a lot quicker than th
