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) ________________________________ Message 2 _____________________________________ Time: 09:27:56 AM PST US From: "Richard Goode" Subject: RE: Aerobatic-List: Spades 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!

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. http://globalaviationresource.com/v2/wp-content/gallery/classic-aircraft-dis plays/img_2468.jpg Todd McCutchan T-34A & Yak-50 Cell: (260) 402-1740 E-mail: todd@fastaircraft.com www.fastaircraft.com > On Jul 10, 2016, at 11:27 AM, Richard Goode wrote: > > 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 p osition do so for aesthetic reasons! > > Richard Goode Aerobatics > Rhodds Farm > Lyonshall > Hereford > HR5 3LW > > Tel: +44 (0) 1544 340120 > Fax: +44 (0) 1544 340129 > www.russianaeros.com > > From: owner-aerobatic-list-server@matronics.com [mailto:owner-aerobatic-li st-server@matronics.com] On Behalf Of Jeff Deuchar > Sent: 10 July 2016 15:44 > To: aerobatic-list@matronics.com > Subject: Aerobatic-List: Spades > > 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 deb ate 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?
