Oh No Doug,
you got the "Spiral Slip Stream" Posse after me

Doug The point I`m Making is Even the BIG Boys argue of the SSS existence If It can`t be DUplicated, Explained, Demonstrated,
reproduced with and understanding of what causes it and Aero Guys still aurgue about it, It is not Sience, Just a educated Guess, They can Create tornados , and vortex, but can`t quantify the SSS
Why can`t they do more than Guess "thats what must be Causing it!"

I`m demonstrating , we toss out words ,terms,ECT. that may apply to full scale aircraft and think we can lump them on Models.
and that just explains it away,

When I started designing Pattern Aircraft
I was told the Stab had to be lowered to keep the airplane from pitching to the belly on Rudder( wrong)
I was told SSS was Causing the airplane to pitch to the Belly on left rudder, But right rudder ,,Not so much (wrong)
I was told down thrust was how you kept an airplane from pulling to the canopy in a verical up line (wrong)
I was told you can`t get the mix out of a airplane because the SSS put unequal pressures on the surfaces,you just have to live with it (wrong)
I was told Wide tall fuses would fly terribe in the wind(wrong)
I was told a heavy airplane flew better in the wind (wrong)
I was told the airplane had to be built with wing, stab set to zero (wrong)
I was told there is no way to perform a Knife edge loop with no Mix purley on rudder command (wrong)
I was told anhedral stabs countered too much dihedral in the wing (wrong)
I was told you had to run the C/G back around 35 % so the airplane used just a little down elevator (wrong)
I was told you need minimun of 2 degrees right thrust (wrong)
I was told to start out with 1.5 deg down thrust (wrong)
I was told a forward canopy rolled better (wrong)
I was told fixed gear were less drag than retracts (wrong)
I was told there had to be a left rudder mix at low throttle (wrong )
I was told you cannot use Sharp leading edges on your wings and stabs the airplanes would be pitchy in flight (wrong)
I was told you cannot use counter balances on ailerons (wrong)
I was told you had to run deferential on ailerons to roll axially (wrong)
I WAS TOLD ALL BIPES HAD TO HAVE THE WINGS AT DIFFERENT INC. NEG ON TOP POS ON BOTTOM (WRONG)
I WAS TOLD TO USE UP THRUST ON THE BIPE( WRONG)
I WAS TOLD TO GIVE UP ON THE BIPE (WRONG) the guy who told be that went back to it after seeing mine HAHA
i WAS TOLD BIPES WERE TO COMPLICATED TO HAVE NO MIX (WRONG)
I WAS TOLD TO BE COMPETITIVE TODAY I HAD TO GO TO ELECTRIC (WRONG) had to throw that one in LOL


These are only a few examples. SO forgive me if I don`t Jump on board.
I have demonstrated these all to be wrong, only one is a oppinion, YS POWER BABY!!
These have been Pattern design Myths that just keep passing down through the generations of Fliers and designs and they are hard to change it`s easy to read this in "RC Modeler" and accept them as fact from good writers and pretty sound logic.

SO forgive me if I can demonstrate there is no design criteria for eleminating the SSS or that it even effects what we do.
Most of what it is blamed on it is due to Poor design or poor trimming.
Our fuses have become the size of garbage cans and our props have doubled in size. Yet ,Our understanding of these two dynamics are stuck in the 70`s design formulas, from our teen age Hero`s.

I know Goerge Hick`s he has verbaly spanked me on the Web( I deserved it ) But Theory and application are two different horses.
Guys like me Prove the Theory for the thinkers. Or disprove it in many cases.
