Here is another link to the Pilots Post site and a report from RV7 owner and friend Juri Keyter and Willie Bodenstein.
Then as requested more info about the race.
This is now an annual event, run in June in Botswana a neighbouring state. This was the third Race for Rhinos.
In theory all aircraft has an equal change to win as it is a handicap race. Your handicap is determined from historical data collected over many years, or a test flight for new to the race aircraft.
The winner is simply the aircraft and crew gaining the most time on handicap.
The maps are given blank and one has to plot and prepare your own map. the scale is 1:250,000 and it is a normal topographic map. This year's map was something else.
Usually there is no height restrictions on the route between the turn points. So one can use upper winds if there are any in order to gain time. BUT the heights to cross at the turn points are 0-400 ft AGL and at the finish point usually 200 to 400 ft AGL.
The Air Observer.
Each aircraft gets an Air Observer to carry on board. This is basically a gps logger setup to log raw data at a 1 second interval. After your flight you hand in your logger. It gets downloaded and super imposed on the course for the day. This then calculates your times and speeds as well as any penalties that might apply.

How do you fly his race. As hard as possible meaning throttle and pitch fully forward and mixture set for max power. Navigating is difficult as landmarks are scarce. One tends to focus on small landmarks like cut lines (farm fences) roads and rivers and small rural villages. Some times the map data is 20 years old - so suddenly you get a big tar road or a mine with nothing on the map!
