Centering the Sub-Trim Debate: An In-Depth Analysis by Earl Haury

Various opinions exist as to how subtrims affect servo travel, especially when used with dual servos on elevators. This discussion shows data that can help understand subtrims. While the measuring equipment was setup I made a few more measurement to satisfy my curiosity. A comparison of the performance of old with new servos, trim effect, […]

Basic Aircraft Setup

BASIC SETUP AND TRIMMING GUIDE FOR ENTRY LEVEL PATTERN FLIERS Trimming an aerobatic aircraft is like learning the game of golf. When you first start out, the game seems fun. You have some good strokes and some good holes, but some call it beginners luck! Then, as you get a little more serious and buy […]

The Real Secret Behind Rudder Authority

This is the foundation of the problems with performance of the model versus the performance of the modeler trying to fly it. The Beginning of Rudder Knowledge With the art of trimming, there is one basic difference that affects your results when it comes to a good flying model: The difference between the model’s ability […]

Measuring Incidence Angles and CG Location

We often refer to incidence angles, CG location, and control travels with respect to our pattern airplanes, but just how accurate are the numbers? Does it even matter? We each may have different criteria for making these measurements. Sometimes it’s just for initial set-up to the designer’s specs, or maybe for future reference as we […]

What Does It Take to Prepare for a World Championship?

Ooph, that’s a good question. I’m not sure I know the full answer to that question yet. If I did I would probably be World Champion. That’s part of competition, always striving to make yourself better, always looking for that next little leg up. Bryan and I never stop pushing for better. You have to […]

Bryan Interviews, Part 3: Biplanes

Biplanes: one more thing the pattern world loves to talk about. Bryan understands them better than most. “What’s up with biplanes?”, you say? Find out!

No Deference for Differential

I recently received a couple emails from pilots with the same question, “How much differential do you recommend on a pattern plane?” My Answer? None! Now this may come as a surprise to some who use it and believe that it works, but if you’re flying with a symmetrical airfoil the biggest reason you may […]

The Job of the Caller

Do you call maneuvers for a flying buddy at a contest, or at the home field ? Sure we all do. Do you know what you’re responsible for as a caller or as a pilot? Well, I hope I can help in defining your job a little better. Depending on the class you’re calling for, […]

Anatomy of a Snap Roll

I love reading everything that Earl writes because it’s so thorough and informative. He does an excellent job explaining the physics behind a snap and how we can use that knowledge to inform our methods for trimming and flying the maneuver. The next time you get in a debate with your fellow pattern fliers about any aspect of a snap roll you know where to go!

The Complications of Compromise: Improve your Progress with a Comprehensive Approach

Having an airplane that flies better than you is a special feeling. However, adjusting and improving the model and radio setup can sometimes be very confusing; you can easily get discouraged and make compromises. When I first started on this trimming journey I had no road map, no direction, and no skill. I only knew […]

Triangulation Trimming: A First Hand Account

The following is an article written by Jason Arnold, an Australian F3A pilot and big supporter of our trim methodology. He has had great success with Triangulation Trimming, and he’s not the only one. Many around the world have followed Bryan’s advice from a distance with remarkable results. We asked him to write about his experience because it’s one thing for us to tell you that we know what we’re talking about, but another thing altogether to hear from someone who has experienced the difference first hand.

Earl Discusses Air Density and Pattern

Have you noticed that some days your airplane has more or less power than others? That it’s more or less responsive? The variable property causing this is air density. Full scale pilots are very aware of air density, expressed as Density Altitude (DA), and its effect on aircraft performance. Low DA provides good performance in […]

Pattern Flying Fundamentals: Roots of Success

When I lived in Austin, Texas my good friend Rene Grebe organized a pattern primer event for our area. He invited me to come and speak a few times, to share my knowledge for the benefit of the less experienced. The following is based on what I presented there but there are countless very experienced, very talented pilots who could benefit in some way from reading. It’s a loose collection of personal observations and tidbits of information that I’ve gathered over the years but I think it’s valuable nonetheless. I encourage even the most seasoned of you out there to take a look – sometimes my most egregious errors and my worst tendencies are rooted in fundamental mistakes.
