Looks much much better
I would say turn down your steering rate on your rudder and it should tame down your flipping issues

Sorry about that guys,I edited the video & made it public :-) .
Me any my Lil' brother went out to Julius Kleiner park yesterday with the boats. Here's a video of the first 5s test run in the mean machine. Its still running the 3674 2350kv mill, m445 prop & as venom 5000mah 25c 5s on the mystery 200A ESC.
It defiantly needs a deeper rudder cause it's hella fast & nearly uncontrollable w/o a deeper rudder. The rudder on it is 4 1/4".

After it torque/rolled & flipped over, it was completely full of water. We called it a day after we got it back in to shore. I split the shrink wrap on the ESC & let it dry out. After that it worked perfect. I replaced the crap thermal tape under the cooling block with thermal paste I use on my computer CPU's, then gave it a liberal plasti-dip treatment & let it dry before/reassembling with the original shrink & alumatape over the cooling block side. Now it needs an xl rudder.

Fix the video!

Alright, I finally got the 200A Mystery ESC I ordered. I soldered uh p new 5.5mm connectors on it & got it installed w/ the Rx tray. I am having an issue with a cell in one of the venom 5s packs holding a charge even though I've never used them,, so I went with a single 5s setup for now.

I used industrial Velcro on the flat of the transom right in front of the servo. The balance point is nearly identical, it only moved about 3/16" foreward, but its still on the middle step, probably 32ish %. Now I need to figure out the esc programming. .....

Most of with the small pond I was at, and the camera angle. The pon I about 85 yards long & 45' across. Watch it mov I ng away from the camera after I got a couple laps in. It was moving pretty good on bout 3/4 throttle a few times. Faster than the 35-40 mph traffic on the street.

I was having a hard time holding full throttle because it needs a deeper rudder with the higher power .. As soon as my 200A ESC gets here, its going for a 5s run on bigger water.

The boat will always look faster to you when its a few feet away vs the cars that are much much further away specially in heavy traffic that is slowing and stopping in the back ground... that angle to the traffic will look faster than the actual speed of the boat
best way to know its "true" speed is using a gps...
a gps to me is a big help in setting up my boats.... also run time vs amp draw

maybe its the settings in your esc not letting the motor run up all the way??
I would also try moving your packs back about 1-2" to help loosen it up more

Looking good, it definitely needs some more open space to "breathe" a bit. Hopefully you can get some video of this for us

Alright. I got out Saturday and got a video with the new setup.
It would have been a bit longer, but the battery in my radio died. the beeping you hear when I pull my boat out of the water is the alarm on my radio going off.
Overall once I started getting the hang of how it handled with the upgrade in power, she started moving right along pretty good

Something is off.. You should be running quite a bit faster than that. How deep is your prop?

Kinda curious to what is going on myself
my MM with a Blue SV27 motor and carbon 45mm prop was a little faster than this..
this one should be moving out faster I would think...

The last time I ran ran this on the 4s parallel setup, the motor was pretty warm. Idk if it was a blockage in the button pickup in the ride pad., or if it wasn't flowing enough. I thought rather than chance it again, I would improve it. I hung a cf tube pickup on the strut, but the bulkhead fitting I had Isnt going to cut it on this thing. The rear bulkhead on this is 5/16" thick, so much for that idea .

I pulled the button pick up out of the ride pad, and threaded in the bulkhead fitting, then used my dremel to cut it to length and slash cut it turning it into a low profile 3/16" tube pick up. Since its located right behind the ride pad step. the water should follow right over it without causing any noticeable drag.

I also picked up 6' of purple fuel line from action hobby today, and replumbed the boat, & installed my Venom 5000mah 5s1p 25c cells in parallel. Now I am waiting for my 200A ESC. It should be here by Fri. - sat.

working over my mean machine ....

Eh, reading back through this thread, I realize I've got nothing out of it lol
I'm just not learning anything from this one.
I mean I've been in here commenting, but mostly ignored or people don't like the way I come off, so I'm out. Carry on guys
Ch33rs!

ha ha ha ha ha , actually if you want to get technical, Jorn' is Norwegian .
Because the sprint cat is essentially the same as the !mm. I talked to him about his setup on his Aeromarine's, and decided to try something similar with mine on 5s, just not as fast

The undersides of the mm and the Sprintcat 29 are the same. The tops are different, and aerodynamically makes a large difference in the way the two boats perform.

I'm thinking he just wanted to share a video with us, it's his thread after all.

Ohkeydohkey...
