Guys
I have written Many, Many Trimming guides over the years.
Even on the old NSRCA list in the late 90`s,
I`ve taught countless guys to trim their designs ,designers and joes alike.
However,
I have written a more concise article that gives you the tools to fix almost any design.
This article is running( in A few sections) in the Pattern section of Model Aviation now, because the article is so large .It explains all the reasons why I do what I do,and how we got to where we are in the current crop of designs,and the reasons behind the changes in what we now fly compaired to what used to be the standard.
all other written ,trimming methods are poor,wrong, to useless at best ,for complete trimming
on our modern designs.

I Explain how to decipher what the airplane is telling you and how to fix it.it`s all about correctly understanding of the feed back the airplane is giving you.
If you have the courage to believe, and the drive to get things right,because it makes a big difference in the end,read it.
These set up tips will directly effect your score in the end,lets face it ,thats what it`s all about.
Use my guide, and have fun learning that everything you thought you knew is wrong

I have no guessing ,surmising or ambiguity, I tell you if your airplane is doing this,or that ,how to fix it.
After designing nearly 20 top pattern models, and helping Top F3A team members from around the world trim and even design their airplanes ,you can be sure the methods are proven.
Just do some research on RCU for my previous post, and read my articles and you will be informed to make the right changes and improve your flying and scores.
