Good to see the strut mods made a big difference to the speed & smoothed the boat out, you need to crack the 80mph now.

Not doubting your numbers but just curious as to the accuracy of shooting radar at the boat from behind. Is the radar bouncing off the boat or the rooster shooting off the stern. I can't get a good radar hit with my JAE FE.

Nice Job!! She looks great!!

Thanks for your support Martin, have any ideas on how to crack 80.
This setup is at the limit al least as far as lipos are concerned, both the Esc and Motor on this run were just warm, the Lipos although 6200mah and 50C were hot, the wires untouchable and it puffed at little.
Different prop more pitch or mm I propably need lipo with more real C over the 50 I'm using not to ruin anything
I also have an Octura 1470 and a Grimm 4255 for this hull, the Octura lifts the hull to much and the Grimm rides just like the H4 ???
Can change Lipos but I can't find any reasonable priced lipos with real 65C and more than 6200mah.
What do you think of Life batts. Lower voltage but I saw the turnigy 4S 8400mah 30C. any good ??

We usually shoot from the front and or the back on different runs.
We have two different radar guns at the lake and there is little difference between the registered speeds .
The speed from the back is easier with the gun on the video, the other gun is really accurate and registers also from 250 meters distance and at any angle ( it's the same one used by local police) .
Try pointing the boat straight towards the gun from the front, it usually works with mine.
