This is Bryan's famous Triangulation Trimming boiled down into an easy to use guide. It contains two heavy plastic laminated pages front and back for sustained field use. 

The guide acts as a flowchart incorporating descriptions of every fault in an airplanes performance. Those faults are listed and have a minimum of 3 associated adjustments which are prioritized from most likely to least likely cause. Adjustments are identified with an associated letter which you look up on the legend of the chart. 

Now on version 6! The guide now includes guidance for canalizers and goes deeper into bipe adjustments and settings.

An accumulation of 30 years of experience in pattern design and competition, this guide serves as your personal airplane whisperer. The only thing better would be the man himself.

"Trimming and designing F3A competition models is a never ending pursuit!

I'm always learning and trying to improve myself against what I feel the correct path is. Every new small discovery leads to more answers. This drive for the ”Extra Mile" of perfection on designs and understanding how a model flies is never-ending.

Being able to compartmentalize each job of each part of a model, adjust them, separate to the other components, and understand how it affects flight quality good or bad is a daunting task. Not to put too fine a point on it but I spend endless days setting the smallest of adjustments, sometimes in the hundredths of a degree, for conditions, temperature, and pressures." -Bryan Hebert

Still soft but looks terrible after 1 wash. Save your money
Color: White, Size: Small, Color: White, Size: Small
Update: sweater looked great when I received. After 1 wash it looks terrible. Looks like it’s been washed too many times, material fuzzy and piled. After wearing it once, it snagged and the knit pulled through. I would NOT recommend. I had such high hopes. Save your money. Very nice sweater, especially for the price! I love the details of the buttons on the sleeves. It is SO soft. It’s not super thick as I can see my skin through it when pressing my hand up against fabric. However, it’s not see through when wearing it. It’ll be perfect in cooler weather and perfect in the winter with a coat but won’t cause me to overheat when in a heated environment. I do feel like it runs big. I could have sized down a size. Although I’m not sure if it’ll shrink after a wash or two.

Disappointed.
Color: Blue, Size: Large, Color: Blue, Size: Large
This sweater is so comfortable and very soft. It fits well in a flattering, oversized way. But after one wash it is pilled everywhere which makes it look old and shabby. It’s at a price point where I feel compelled to return it.

Perfect for casual wear and dressy style
Color: Dark Green, Size: Small
This sweater is soooo soft and the color is so rich. The fit of it is perfect, not too tight and not too baggy, just right and I used the size guide to pick my size. Just for reference, I am 5'3" and 130lbs, 38C bust. It's well made and washes great. I chose to hang dry mine as I typically don't put any of my sweaters in the dryer to dry, just to fluff them. I have this one in two colors, the green and the tan/beige and I would say they are both a true representative of the color shown.

Love the long sleeves!!!
Color: White, Size: Small
Love it! I'm 5' 11" tall and I purchased this according to reviews. Several people commented on the length of the sleeves. I have a hard time finding sleeves long enough if it's not " tall" sized. It was perfect for me. If this washes nice I'm going to consider purchasing more in other colors. I ordered the white and just love the long ribbed cuffs with the line of buttons. Very soft.

Nice cozy sweater, but handwashing is recommended
Color: Beige, Size: Medium
Soft and cozy, but does not wash well. Goes with everything. This sweater fits well and looks great. I received lots of compliments while wearing it.
