Possibly the fastest revolt in the world

[Speed3]

One more thing I measured the 131 feet after the video was taped.
I studied the video and I used the images of the buoys for reference to know where to measure.

I factored in the angle the boat was running in relation to the buoys.

Just as you see the little buoy out left at the start of 7 seconds depending what the video is view on and the view used to see it.

Along the road when I lined up with the little bouy I walked in a straight line and measured the distance to line up with the bigger buoy at the 8 second mark.

131 feet.

Measurement was taken to get an idea what the boat was really doing. Based on what I saw and timed in the video.

I live close to the area so I went back down to the location after studying the video thoroughly to get the measurements. Based and what was seen in the video.

Another hint when you seeing the little buoy at the start of 7 seconds you cannot see the big buoy because it true a good space between them.

You may also find it difficult to get the little buoy and the bigger one to appear on the same screen in the video. It takes up almost the length of the screen to capture the two of the bouys.

I think he's right. This same approximation method is how NASA calculates speed for aerospace. The key is to close one eye.

I stand corrected..looks like warp factor 4 now.

...The revolt is atleast 1.6 times faster than the impulse which did 47mph. If you judging hard.

But wait, is it 68 mph or 75 mph or 100 mph? Changing the claimed speed multiple times when challenged does little to add credibility to the thread. Instead of a misleading video, why doesn’t the OP just put a GPS in the boat like he did with the Impulse?

Does the boat have the motor rpm and prop pitch to even reach those speeds? Is it running 4S, 6S or 8S? What Kv? What prop? If the OP wants anyone to believe his claimed speed (whichever it is) he’ll post the specs of the boat and run the boat with a GPS over the same course. It is a nice running boat, but it’s not a 100 mph boat.

If you look @ the description posted with the video it is a Leopard 4092 1730kv on 5s with m545 prop, calculates to mid 50s.

[martin]

32000 rpm unloaded on 5s so around 28000 rpm loaded on m545 prop, no where near the claimed speed.

This is it running the week before.

I don't know for sure how fast it's really doing but I think it over 70mph for sure.

Other boats I know doing over 50 on gps I know is nowhere near what this was doing.

I had bad experiences with GPS which is why I choose to make videos and measure points and time off of the videos.

I was racing someone who was high 50's close to 60 on GPS and me and him had a real close race.

I racing racing with the impulse 31 v2. When I GPS after the race it did 49mph according to the GPS. The boat race 325 measured feet in 3.57 seconds so I know it was much faster than 49mph the guy I raced was almost identical speed may be slightly faster, but he was getting close to 60 on GPS.

Our race in the video above.

So I don't have much confidence in GPS because of the above.

You need to stop "thinking" how fast you are running.

The calculations don't add up.
The videos you posted don't add up to anyone with some experience.

The short speed runs you are doing wont even give your boat a chance to get to full speed.

You do however have a very nice running 50 (ish) MPH boat.

Keep on messing around with it...thats part of the fun!

I think you need to use at least 250’ of straight on your runs. Your GPS readings are inaccurate because your acceleration bursts are too short. You need to keep in it for a least 2 seconds.

Thanks for the feed back guys.

I went to the location of the video and identified some items on the land that I was able to identify in the video.

The objective was to identify objects on that land that's parallel to the buoys.

In this way I was able to connect the buoys and the items in the video.

This help me identify the area in the water which would be the starting point. And the end point.

After identifying the point then timing the boat again I got 1.37 seconds. Through 131 feet.

65mph.

I know that speed seems a lot for my setup. But I did some stuff to get extra power out of the motor.

I am able to run 15 degrees timing on my d wind 4092 and still have the wires, connectors, motor and ESC at 95 degrees Fahrenheit. The temperature like it don't change the only thing that gets hot is the ESC capacitors.

The power I am getting you will not get normally. I am accomplish the same thing with the 2080 kV 4092,

[fweasel]

And your speed comes down again. Ready to concede your method is tragically flawed?

[Speed3]

I opened the wires coming out of the motor, scrap on isulation, then put the ESC wires inside the motor wires and soldered it with flux. So its almost like the ESC wire and motor wire is one solid wire.

The battery connectors are firmly connected.

The revolt trim tabs were set to keep the boat from blowing off.

So a typical revolt cannot get close to the speeds I am doing in my area.

And the 4092 likely will not put out the power I am getting.

So trying to calculate what I should be doing would be offset.

Because of how stable my boat runs it enhance the propeller efficiency too. No bouncing or chine walking it is just planted.

Also the boat total ready to run weight is 5 pounds 3 ounces with batteries.
