Recently the designer of the Spark e-mailed me and said He liked my Bipe and He was designing a Bipe, and wanted to know my Bipe setup.
I Had a weak Moment and gave a setup to him LOL
So you might be able to pry that one from him, But I cannot just give that info Out anymore. It has cost me 20 Years of my Life, I think it may be worth something.

I figure if you can Buy My designs, reverse engineer it, and just look at the common sense and experience in it, we both win
Every think I do to a design is proven purpose.
Every body knows when they eat a Cake "mostly "what is used to make the batter, and you know all cakes LOOK good ,How much of whats in the batter gives the outcome for the "good" cakes. The chefs never tell what the recipe is for the really good cakes, they would no longer sell the best cakes LOL

Every airplane designed today for competiton by active competitive pilots" Not the knock off look alikes" are worthy airplanes. It is the small details that are missed,what cannot be seen that seperates the knock offs, Competition and understanding of the needs of the airplane in competiton is what makes the really good designs. and they evolve from this. Thats Why My airplanes look like My Airplanes or CHip Or CPLR`s airplanes look like they evolved from a educated Idea. We have a philosophy that evolves from understanding What the goals are.
WE are involved enough and lucky sometimes to see the new power plants available ect. and design around this knowledge before the average guy even knows about new products are being developed around the corner.

An airplane that is not well thought out or designed , starts the chain reaction rolling, and the mixing begins. this mixing seems to be Mystical and we actually like that about it, it gives us endless hours of debate about what it might be. I go out and find what it is, refine it in the next design, and eliminate it. usually when you find the cause for one mix,it is actually the fix for two other problems. they have a way of compounding problems.
We waste our time putting bandades on the sore ,and not curing whats causing the sores. and our new radios actually enable this.
Ever notice every Bip out there has the same wing area ,Why every body copies what they think the other person my know!
I copy myself. and improve on what I know ,When I try to improve on what somebody els knows I fail.

Refinements come from understanding the Needs or Goals of what the Purpose is for the design, Everything done in the design needs to be in Harmony with the Purpose of the design. from the gear to the paint.
Available Power, for the most part, drives the advancement of the design and gives the flexibility in the setup Thats why Props are so effective in changing how a airplane feels , But most can`t feel the good or bad that prop may do to the setup of the design.
I try to design with everything in mind.

Most Guys don`t realize that by having thrust off set in the engine it actually robs power from the prop! this is a small but important detail.

Here is my secret in a nutshell.

Every thing you do the airplane that changes the force required to fly it straight ,causes three other problems (triangulation
This in turn affects Everything and I mean everything , we do to get the airplane to fly without mix. From throw to expo`s
Understanding what percent to make an airfoil,or how much wing area is required to make the aiplane fly without compromising the trim of flight, to how big to make the ailerons ,or how much fin and rudder to use, all contribute to the ability to trim the airplane without mixes.

Then having the skill to seperate these out and find the flaws in the setup, or design ,is what sets me apart ( in my oppinion )
I have had countless students to this philosophy,and very successfull students I might Add
All from a old Coon Ass from down the bayou.
