FILES & LINKS

National Society of Radio Control Aerobatics is the SIG for pattern. Here is a link to the site. Great magazine! Join today!!!     

The Great Rudder Experiment.

This is the article I published in the Jan-Mar issue of FLORIDA AEROBATICS. It includes the original graph

RCM Flight Training Course II

The first book dedicated to getting one started in PATTERN. It's got old photos, sequences, and diagrams in it, but most of the core ideas are still fresh and applicable to the sport today. Includes construction article for Miss Norway. By Tom Cone and Ben Strasser. 150Meg .DOC file

Pull-Pull

Some notes on setting up your PULL-PULL controls. This will help you get the slack out!

IN FLIGHT VIDEO FILES

SL-1

SL-1 900MHz antenna testing with a little pattern flying thrown in.

Saturn

Sometime around 2001-2002 I took my Saturn and video system to a fly-in at Mac Hodges' place in Georgia. As I recall, this flight was pretty scary because there were so many planes in the air.

Spencer

In-flight video around 2001 at Tony Stillman's contest at Spencer field in Pace, Florida. I experimented with both forward and aft facing cameras and each has it's advantages. Originally recorded on VHS, it's lost a little clarity with time, but still a fun watch. Edited between two flights, alternating fore and aft views.

aresti.zip

This is a xip of two CorelDRAW 8 files, aresti1.cdr and aresti2.cdr. They include the diagrams originally seen on Matt Chapman's page . There is enough variety of symbology in them that you can piece together about any aerobatic sequence imaginable, but if you imagine one that you can't, let me know and I'll try to add it. (29k)

Former11.zip

This is a CorelDRAW11 script file for drawing formers/bulkheads to Dave Platt's specification. This is mathematically called a "parabola rotated 45 degrees." The script was written using a string-art algorithm to generate the shape, so you will want to use 30 or more points. It will also show skin thickness removed. If you want to design a turtledeck, etc, this is a nice shape to use.(2k zipped)

airfoil11.zip

This is a CorelDRAW 11 script file for plotting airfoil files. Reads .afl and .dat files.(2k zipped)

This is a .jpg schematic of the Futaba ZAP Transmitter battery magazine. It shows the battery, diode and connectors.

This is a clearer picture of my paint jig, this time in Corel 8. Zipped, 16k.

magicgad.zip

Replacement parts for IVAN's MAGIC GADGET. This is a handy protractor device for alignment of control surface throw. Originally produced by Gator R/C, it has been discontinued for several years. Includes replacement meter scale and aircraft log sheets. If you're not familiar with how to use this, a pointer is temporarily attached to each control surface with the pointer end five inches from the hinge line. Five inches is the distance between the two red arrows on the meter scale. The meter face is mounted to a plate that is in turn connected to an articulated stand adjusted so that control center is at zero degrees. The red arc on the meter face corresponds to the five inch distance from the hinge line, and thus pointer end. Zipped CorelDRAW9 and JPG, 932K.

Element.zip

Build components for BJ Element (and maybe Agenda) ARF. Photos, motor mount for Neu and Plettenberg, re-enforcements, Visio files, Castle ESC DAT files. Zipped, 2.03M.

PRODRV.ZIP

This is my rendition of the schematic for the older Radio South PRO DRIVER. I doubt there's enough information here to build one. And who'd want to bother? They're too cheap to buy. Anyway, this is presented here in case you're curious or live out in the sticks somewhere and need to do your own repairs. Both versions are in the zip in both CorelDRAW and Windows metafile (.wmf) (186k zipped)

guillowsno3.zip

Zip of photos and tracings of Guillows #3 C/L trainer. Drawings in Visio.(1.6M)

rainshd.ZIP

Here’s a nice rain protector for your transmitter. Constructed from a sheet of thin flexible plastic sheet, preferably clear like canopy material. Use at your own risk! Windows metafile (.wmf) (2.2k zipped)
