The objective of this publication is to provide the NSRCA Historical Site Repository with a go to “Pattern Trim Bible” of previously published precision aerobatic trimming articles authored by world famous pattern personalities. This document places trimming information and trim charts in one master document eliminating the need for readers to search the net for the data. These reprints of previously published articles are a nuts and bolts class in precision aerobatic flight trimming
authored by World, National, TOC, Top Gun champions, pattern plane designers, and a manufacturer of quality modern day pattern planes. So take a look below to see what and who will be featured in the narratives.

Debunking decades old myths about prop performance

The pattern community learned a lot from the prop testing groups during the 1980’s – 2005 time frame. The following article is an expanded master document detailing several group findings. I was a member of the groups and the data was morphed into a summary version that appeared in the Pattern History 1950’s-1980’s 203 page book available on the NSRCA Historical Site as a free download.

Blade Tracking - Vertical and Horizontal Prop Balancing Techniques and Balancing Spinners

The following chapters are a continuation of the previously published Prop Testing story of the
1950’s -1990’s. The story starts with the evolution of prop and spinner setup procedures that
eventually resulted in reduced noise and vibration levels. As the story unfolds the reader will see
dramatic advances between a 1950’s prop setup typically used in the Smog Hog days and the
progression to more efficient, accurate and modern setups used in the 1990’s.
