GP335V2 20 SPORTS Hydro

[electric]

Thanks on the paint job. It was only my second attempt at trying to get a high quality finish doing it myself. I learned a lot about painting and also that is a LOT of work to get a nice finish.

[BAZCNG]

I have done a lot of painting on Buggy body's but as its done from the inside the paint finish is always good lol

You say that you are running 66 MPH with your "P" Sport Hydro
Your video shows 4 laps in 61 sec. (= about 50 MPH)
Have you ever run it with a GPS in it??

My "P" Sport only runs at 63.2 MPH on the oval
78 Sec. for 6 laps running in about lane 6 to 10.

Larry, nice !...love using GPS in vids to show proof...what motor is being used for that run ? DJ

I'm a bit late, but thanks for the info in your posts #16 & #17.
The most I do to props is thinning & sharpening, de-tongueing, back cutting, reducing diameter, & of course balancing. I haven't ventured into the whole cupping & pitching arena yet.
We can't run such aggressive props here in Oz because are only allowed to run 1P packs, with a weight limit of 650 grams for a 4s pack. That restricts us to between 5000mah to 5800mah depending on the brand of packs.
Thanks again.
Paul.

Yes, Larry the speed I got was from my gps. It represents the top speed on the run, not the average speed per lap if that is what you are calculating. Did not mean to imply that my average speed was 66.1 mph, because really never measured it the way you are. According, to you, I thought I was fast, but now I think I may be slow. chuckle. The average lap speed would also have a lot to with how tight you are hugging those bouys as well.

Larry is using a fairly old but, solid NEU 1515 1y.

Larry, wait, I know why you are getting those numbers on my run, it's because on that run you can see the radio is cutting out and I am stalling a lot. It came to a dead stop a couple of times. You will see how the boat disappears in the video(because it stopped) and then starts going again because I was having radio problems. I am driving the purple one.

Paul, that makes sense to me. We are running 4S2P so we are usually pulling in the 160amp to 190amp range with spikes that go higher. That would be a challenge on 1P!!

[TRUCKPULL]

My 63.2 mph is top speed on my run.
My 78 sec. was running really wide.

In your video I timed the boat that was in first place. ( 4 laps in 61 sec.) = 91.5 sec. for 6 laps.

Why are you pulling such high AMPS.
My N2 Sport pulls 190 AMP average.
My P only pulls about 140Amp average during a race.

Jim what timming is your ESC set at??

Yes, it was in first place, which proves the other boat was slow, but my boat stops completely and then hauls butt and catches back to the other boat stalls again and then goes again to win. Kinda like the tortoise in the hare. I am going really fast and then stopping, and then going really fast, stopping. Then it was stumbling a lot. Make sense? I am pulling high amps because I am over 65mph when I am going.

[TRUCKPULL]

???? When I stepped my boat up from 58 to 63 Mph my Amp draw went down.

What is your timming at??

Larry,
I did a dump of my notes off of my iphone. My esc data is at home. I am not sure if I have it, but I bet I may have the dump from that run where I was getting 66.1mph and I can show you the esc readings. Why not share right...here are my notes from some testing I did with the boat. They are bit cryptic as I just talk into my iphone and have it do the typing. My last entry has me figuring out that the boat is going fast, but I did not have enough battery to complete the race. That is when I was running the 3300mah hyperions and then I went to the 4000mah dinogy's and started using the prop. What kind of prop are you running Larry? I was going to try on some ABC props, but I like what I am getting with this modified x455 and have kinda just settled in with it.


Gp335
Abc 1816
47 mph
Ran perfect

Andy Brown Prop 2 laps
48mph.
A little less lift

Third run
Top speed 60 miles an hour
Motor about 115
ESC cool
Running a 452 prop
Added weight
Choppy conditions

Fourth run
TopSpeed 58.5 x452 prop
Motor Temp 130
Choppy water
Handled great
Negative on it to trying to get the rear end off the water a little bit.
No data from ESC had to upgrade software

5th run Changed prop x455 Upgrade esc software required Two lap short run to record data and then measure temps Changed timing from 10 percent to 5 percent Top speed was 66.1 mph Handle great Motor temp was about 135. Warm Batteries were good Over 1 mile 6th run Batteries had only 25 to 20% left on five laps .8 miles Top speed was 57.5 mph Motor near 140

I realize the GPS is just a snap shot of a speed in a moment in time so the boat is going slower than that overall, but frankly I am not trying to say that I have the fasted oval lap boat around, just trying to figure out how to race against the guys in my club and I know I need to be touching that 65mph zone to even be in the race.

Changed timing from 10 percent to 5 percent

Do you mean 10 degrees to 5 Degrees???
