A small experiment

Would anyone like to carry out the following experiment?
Upon touchdown on a sealed runway, close the brakes, don't use the
wheel brake and see how far the glider rolls.
If you feel like doing this please let me know the results and include
glider type, approximate weight, wind, altitude, temperature, slope.
I'm trying to find out the frictional forces acting on the glider on
the ground as part of the ongoing jet project. Some statistics would
be nice.
Thanks.
Progress seems to be rapid amongst the jet engine manufacturers in the
last few months with one 22Kg thrust engine available and two 25 Kg
engines in development including one with a really neat 11 stage axial
flow compressor.
I'm convinced these micro turbines are a breakthrough, disruptive
technology for soaring.
We have a small group in SE Queensland working on applying these
engines to gliders.
