Hi All!
I have found that some of the smartest people are here on this site. I wish to measure the speed of an R/C submarine using pressure sensor(s). I have seen the "wheel" types which seem very large. It would probably be very unsightly to have a long pitot tube sticking out the front. It just seems "logical" that if you measure the pressure of the water on the bow you could somehow calculate the speed? Yes I did look at the "eagletree" system which uses a pitot tube and I doubt since they sell sensors they would wish to provide any information. Any ideas would be very much appreciated.

Thanks in advance.

Ed
