Madracer if you will to share the setup, prop, motor size and kv, ESC, battery capacity and c rating I might be able to tell you the likely speed out come.
Native Paul crazy thing is ampdraw is not the issue with us. We have much longer runtime based on my research but sadly less speed.
Did you guys see my last video. My revolt was significantly faster on 5s than when it did 54mph just by using more powerful batteries.
Them smc cell are really good.
Reducing prop diameter will slow the boat down.
I have used the grimracer 4255, octura x442, x642, m545, m645, graupner k42 and ABC 1814 17 45 2 blade.
The graupner k42 have 150 percent more runtime than the grimracer 4255.
And its a lot slower too.
The stock spartan did 35mph on 6s with the stock spartan prop.
The octura x442, x642 and grimracer 4255 give a big advance in speed over the k42.
The m545 and m645 gives another 4 to 5mph faster than the 42mm props.
The ABC prop let me down I took much longer to get on plane and the little sail I got before wringing was a lot slower the the octura.
The m545 was .5 mph faster than the m645 at a lower cell count on GPS for me.
The m545 give a bow lifting effect and the m645 ran more wet.
So I think the loser running was the reason for the speed increase over the m645.
I cannot run more than the m545 on 5s with my revolt because my 4092 size motors are putting out too much torque. The coupler cannot hold the upgraded shaft beyond that.
I am getting my motors to put out far more power than my running mates. They buy better ESC and all kind of stuff but not getting the power that I get.
It have a few of my running mates who get the motors to put out good power though.
But mine run cooler.
I have seen my run mates run bigger props than me without the problems that I describe but that is because they are not getting the power that I get.
But back to you madracer if you share the setup I might be able to tell you the likely speed.
