Making Weight

“Making Weight” is a weird term that refers to a pattern aircraft being under the maximum weight allowed by the rules. The term has come into vogue with the advent E power which requires weighing with batteries that may weigh 25% of the total airplane. While local contests generally don’t verify the weight of aircraft […]

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, […]

LiPo Battery Anatomy, Fire Behavior, and Safe Practices

Most of us who use LiPo batteries recognize that there’s some risk involved. The things have been overcharged, shorted, cut, nailed, etc. in numerous U-Tube videos that dramatically demonstrate the potential to make smoke and fire. There are also a variety of methods offered to minimize risk and manage a fire, with some being better […]

Sbus Worth the Fuss?

The typical discussion for using Sbus revolves around reducing wiring clutter and usually moves toward a discussion of individual servo leads providing some redundancy advantage over a single lead for a bunch of servos. A reasonable discussion, as far as it goes. Are there other reasons to use Sbus, especially in a pattern airplane? Probably. […]

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 […]

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 […]

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 […]
