Broke into the 70's on 3s with a single drive 32" cat

Ok. I was able to make a kinda fair comparison. Even tho the cells were lower charged it still went faster. Fastest pass on 3s I made before was 73.0. My first pass on 3s with the same prop was 76.7mph. After swapping props a couple times and a few passes later I managed 81.1mph with the packs at 4.09ish. Whoohoo. 4s was unfreakingbelieveable! I'm starting a new thread for that one because this one seems to not have any interest.

To update this, my latest 3s passes resulted in more speed. I shortened the rudder a little.

Making the rudder shorter makes less drag lets the boat boat air out a little more if tuned right...To short you F yourself up Just depends on weather condition!

Lol I found that out! It liked it on 3s but 4s wouldn't stay on the water. I may need to do some more tweaking. It would be pretty awesome to get 85+ on 3s out of it.
