[NSRCA-discussion] New Judging tool....... ;)

Just in case some needed a more thorough explanation:

Thrust to weight ratio is around 2. Newton taught us that F=MA. 
Therefore, with a thust of around 10kg and a mass of around 5 kg, 
that's how you get a ratio of 2 which is equivalent to the accel. Accel 
should pretty sporty any way you look at it......

Eagle tree does this same thing with their micro logger.  I have played
with it a bit and its pretty amazing....you can see how straight you
roll down the runway LOL :)

Problem is with the wildly varying attitudes in pattern I routinely
loose the satellite link, so I think I will end up needing two sensors
mounted top and bottom of the fuse to make it work properly.

I think once its all setup it will be a useful tool for evaluating
geometry on things like a rolling circle which is not easy to see from
a pilots perspective.

The airspeed is rather revealing, the acceleration of these planes is
remarkable, easily rocketing to 190 kph in only a few seconds.  Should
take it to the drag strip LOL :)
