Weight and Balance

This software was originally designed for the Ultralight / Experimental aircraft builder/designer to assist in weight and balance calculations also works on conventional aircraft.
It is also easy to use for everyday flight planning. Runs on Win95/98/Me/2000/XP

Program Overview

This Weight and Balance software is designed to make CG calculations easy and fun.
The program interface is designed so that the CG and weight of your project is automatically calculated with a minimum of effort. Just enter the results of your weighing the 3 wheels. When you change any of the weights in the entry boxes, the total empty & loaded weight and the current empty & loaded centre-of-gravity are instantly displayed at the bottom of the screen. If you want to see the effect of adding components, such as a battery or radio, you can use the "What If" feature. This will calculate the CG for you dynamically and allow you to see the result of adding the weight at a specific location within the aircraft. Another unique feature is the forward and aft limits calculation, If you do not know your CG limits you can use this great feature by merely entering your wing cord, a fore and aft limit will be calculated based on an acceptable CG limit envelope. This software also has a very helpful section which will explain the weighing process in easy to understand detail including graphics.

Ground Adjustable Oil Cooler Cover

The "new" Tundra Cover is designed to fit your Rotax or HKS oil coolers, install in front or at rear. It is ground adjustable, so you have control of your engines' temperature.

The Tundra Cover is made of lightweight H.I.P.S. (high impact polystyrene) which is quite strong and will resist damage. The unit covers the standard Rotax cooler set up and allows for a controlled airflow to the cooler - anywhere from 100% closed (for engine warm-up) to 85 - 90 % full open for very good cooling and anywhere in between to maintain any desired temp.

A lot of design and testing was undertaken to develop and test this unit in the coldest of flying conditions to the hottest (in Canada), followed by a year of practical flight testing.

Comes complete and ready to install.

Here's a better way to get your engine's temperatures back in the green, so get rid of that Duct Tape and cardboard!

The Cover is easy to install with all hardware supplied using only simple tools.
