Hello Geoff, thank you very much for your answer. this year have not been to the jet power but next year I will ....
The images you sent me are very helpful for me, my Tuono is the first prototype made ​​from Pirotti (the one decorated vodafone mercedes) had a 120mm edf and I have to convert it to turbine .... I will send you pictures soon.
Thanks again.
