I dont have a doppler, but i have run Graysons for a while now on my 28" profile cat with a 5x5 prop and have clocked it at around 75. It would go faster but my plane started shuttering at that high speed and i had to back off. If i had to guess, Id say 75 to 85 MPH.

Doppler speed

I had to assume a temperature of 14deg F as it looks pretty cold. If thats about right, I got around 78 mph.

80 MPH, thats fantastic Even after reading up on the motor I only really expected 65-70 with my (assumed to be over rated)Mystery lipo. Now I have to learn to fly fast and low. Out of the 20 or so passes past the camera, it was only actually in frame and level for those few.

Same setup as you but with a APC 6x4 prop I got 87mph.

Try APC 6x4.
