Opto-Electronic Timing of C/L Models
My own invention.

A new software release is available! Visit the Transitrace User Web Site!

Was used officially at the 2004 World Champs and the 2005 European Champs, and likely will be used at every W/E/Champs event in the future.
I was awarded the the Antonov Diploma for technical innovations by FAI for 2004 for this development.
Goodyear Racing and F2F
A simplified form of Team Racing with " profile" fuselage and 1/8 scale rules. See below for my " Li'l Quickie" design and the full size plan offer. Read the Description and Building Hints ! Also the hints on Finishing and Wing Pressing. Now superseded by far by this French article.

My Cosmic Wind lacks a plan, but I have GIFs of a 3-view of the prototype: Part 1 | Part 2
The SMFF C/L site now has a List of Goodyear Designs and Plans. In Swedish, but you can understand at least the tables and addresses.
