AIr Temperature V Isopropyl nitrate Level in Diesel Fuel
The first file is a graph of the recommended starting point for the level of the ignition improver Isopropyl nitrate in diesel fuel at a range of different oil levels.
Temp V IPN level at 18-10% oil.pdf
An explanation of the graph above also exists as a free standing web page, just click on the title to the right and the page will open for you,

Vintage A and Classic FAI Speed Calculator Graph
If you are flying around in circle you will want to have a table that will gives you your average speed for 10 laps, now that Vintage A, Classic FAI and F2C all fly the same line length this handy table can be used to find the speed of these classes:

Propellor Pitch Data For Common Team-Race Props
This handy table shows the prop pitch data for some common team race propellors, some pitch data comes as a complete surprise so never believe as gospel what they stamp on the prop mould:

RPM Calculator XL Spreadsheet Program
This file is a simple RPM calculator, if you know what effective pitch you have on a propellor and measure your airspeed, you can work out the effective RPM that you engine is turning. Attempts to use this calculator any other way will just lead to performance disappointment:
Teamrace Results XL Spreadsheet Program
This is a team race XL spreadsheet, and will automatically work out the the fastest heat times for a race for you and allocate positions as you go. Just remember to read the instructions on the spread sheet and follow them otherwise the darn thing does not work at all:
Venturi Chart Area V Venturi Diameter V Spray Bar Size Spreadsheet
This spreadsheet has undergone many modifications and thanks to many hands is indeed very useful and is invaluable to me. Using this chart one can work out the venturi area of a range of venturi diameters and the table also takes account of the spray bar area if you are using one. A very useful table for the teamrace Guys and Gals: Venturi Chart Area V Diameter V Spraybar Size.pdf
VHT Engine Enamel Temperature V Drying Time Graph
VTH paint take time to dry and the time is dependant directly on the temperature after spraying. This graph gives the user some idea of the minimum drying time to hardness at a range of temperatures so you can alway ensure the paint hardens and stays on for that first flight. No more purple hands for the pitman.

Fuel tubing solvent compatibility guide
This is a table I have prepared that shows which fuel tubing materials are compatible with different solvents that may be used in our fuel formulations. This is the manufacturers design information so it will be reasonably accurate.
However one must take into consideration that are fuel formulations are mixtures of many solvents and this will definitely effect the reaction between the solvents ability to damage the tubing material either way. Also diesel fuel ignition improvers are not listed or taken into consideration.
Also please note that as far as the Manufacturer is concerned TYGON ® tubing is not as fuel resistance as we commonly assume, especially with respect to resistance to damage by Kerosine and diethyl ether.
