FES actual thrust for self lunch

[opcod]

Hi
We see many glider with the FES ( front electric sustainer) The low weight one, like the Silent and Lak can take off with the fes system over their 20kw/22kw engine. But what is the actual thrust that this give ? The 1meter prop is quite small.
Anyone have data of a glider running the FEs at full speed and a fish scale to measure the thrust at the other end .. ? Like a static test or so..

Thanks
