Another youtube video, working on some of the things learned at Oshkosh, also hunting for lost boat.

Les:
That was sooo much better - now to work on a lost girlf-friend with a picnic hamper on the wing back brace...

nice
what resolution you got it set on?
-
I will work on that one. Years ago new a fellow that had a heavy ultralight pn floats that flew around the delta hunting for parties. Would land and asked if the nesded beer.

Les were did you get the airspeed thingy on the jury strut?
Nice video
-
From aircraft spruce. Hall effect air speed used on ultralights

Is it accurate enough for primary instrument for speed ?
-
I have used one for many years on my ultralight. There are slight accuracy issues when flying into a head wind and when flying down wind but for our purposes it works fine.

Uhhhh...how is that again? :)

I used the Hall wind meter for a couple of seasons on XL-58. As to whether or not it is "accurate enough" depends on your expectations. It was the only airspeed instrument on my Eagle and I found it adequate for general use. If you need something to nail down precise power settings and landing speeds then it probably won't have enough resolution. It is also sensitive to angle of attack at low (landing) speeds.
But a proficient pilot doesn't need an airspeed indicator on a Legal Eagle for safe flight. Learn the characteristics of the plane and you will rarely check the instrument.
Having said that, I now have a conventional airspeed indicator on XL-58 and find it useful primarily as a VSI since I don't have an altimeter. If airspeed is decaying, we must be climbing...if it is increasing, the ground must be getting closer. :)
A very useful flight instrument for learning the Eagle is a lift reserve (angle of attack) indicator:

It is far more accurate than an airspeed indicator for analyzing stall characteristics. While I had it on the plane it was the primary instrument instead of the Hall meter.

Thanks Guys
@Sam i have read all your site - awesome information
