Default Doppler????

Can someone doppler this for me? I know its probably in the wrong thread but most heli types are not interested in high speed. The pass doesnt sound very fast but in person it looked like it was fairly quick.
Thanks

Great thanks you, however the temp was about 35 degrees C. not sure how much difference that will make.
