Adam,

I've got one somewhere around here but I also have an idea about a better one which will let you easily balance the pitot - static time constants which you do need to do.

G'day all,

An odd question to throw out to the group, does anyone have a drag rake instrument that they'd be willing to lend out? I'm keen to do some flight data testing on my Ventus 1.

Particularly to determine optimum flap settings* for differing wingloadings, but also perhaps to experiment with turbulator chord positions and thickness.

*the flight manual & Dick Johnson FTR's show differently, as I'm sure Idaflieg would too!


Cheers,
WPP
