Hi All,
I figured this list might know the best...
I'm putting spades on my newly finished Wag-A-Bond (no I'm not here to deba
te spades, I'm an experimenter, so I experiment).
I'm wondering if anyone knows why most high wing aerobatic types only have
spades on the bottom?=C2- Or more so, I want to only put spades on the to
p, and I'm looking for a good reason not to?My plane is short and a spade h
anging down will cut me one day, so I thought why not put it on the top?=C2
- I've used Google and to date I've had no luck trying to figure out whic
h is better?=C2- In both cases the spade should be running in smooth air
(up until full deflection).
Thanks in advance,Jeff(Pitts, F1 Rocket, Commanche and newly finished Wag-A
-Bond)

There is no aerodynamic reason why spades should be mounted under the
wing rather than above =93 but I suspect those that choose the
under-wing position do so for aesthetic reasons!

Hi All,
I figured this list might know the best...
I'm putting spades on my newly finished Wag-A-Bond (no I'm not here to
debate spades, I'm an experimenter, so I experiment).
I'm wondering if anyone knows why most high wing aerobatic types only
have spades on the bottom? Or more so, I want to only put spades on the
top, and I'm looking for a good reason not to?
My plane is short and a spade hanging down will cut me one day, so I
thought why not put it on the top? I've used Google and to date I've
had no luck trying to figure out which is better? In both cases the
spade should be running in smooth air (up until full deflection).
Thanks in advance,
Jeff

Perhaps there could be some blanking or turbulent air at high AOA for spades
on top of the aileron? Spades on bottom may also be more effective due to t
he hinge point (longer lever arm?).
Here is a pic of a Pitts with spades on top of the wing.
