I think your build looks very nice, whats the hose covering?? not sure i would trust that esc though........................ should rip on 8s i'll be checking back for a video!

[JackBlack26]

Man, that looks great. The aluminum under the ESC is a great idea. That's what I did in my Gen. That way if it smokes it wont burn the hull.

Also, the outlet facing up should provide a bit of back pressure keeping the water in contact with what it's cooling longer promoting better cooling capabilities. Cant wait to see it run

I assume you mean the black over the water hoses? It's just black braided loom with shrink tubing on the ends.

What's wrong with the esc? Have you had a bad experience with them?

Thanks Jackblack. I appreciate the feedback.
Im not sure if the second line in your post is in jest or if you missed that thread but yeah, I mostly did the outlet that way just for something different. Not really a whole lot of function to it, but I thought it looked cleaner than on the side of the hull for some reason, and its pretty easy to get to if the hose needs removed/replaced.

ah i figured it was the braided loom, cleans things up nicely, i actually always thought putting the water outlet facing up would be cool, especially if there was enough pressure to shoot it out like a seadoo, then you wold really know if you ever lost cooling! lol

No i have never had one of those suppo esc's, i just read a few posts about them being way overrated for what they can actually handle, i swear theres a topic on here about them somewhere.

Well I hope this one's not overrated, as its only rated at 80A!
Im a little unsure about how this esc will do, but only because its just an 80A esc. I like to run High voltage/High current ESCs but Im trying something different for this build. Im going to have to run a small prop on it to keep current draw to a minimum. If it works out I should get awesome runtimes out of it.
Wish me luck!

Just got back from her maiden.

Speed and acceleration were actually much more than I expected, especially with the little m440 I ran on it. You definitely have to ease into it if you want to keep this boat in the water. Acceleration was overwhelmingly powerful...a surprise with the m440. At full throttle, it held the water very well. This would be a great choice for a SAW hull in my opnion. It turned quite well to boot. Definitely the best handling cat Ive owned to date.

The higher RPM/smaller prop combo seemed to work well. Handling is great, speed and acceleration are there, and runtime was awesome. I ran for a good 10 minutes on 5000mah (majority of that time was lighter throttle) and the lipos came back with 3.77v/cell. I will be curious to see what runtimes are when I have flatter water and a rescue boat, so I can be heavier on the throttle.

Temps were...well, irrelevant. I didnt even temp anything, it was all cold to the touch. Two days ago the pond still had a layer of ice all the way across, and there was still a small patch of ice at one end, so the water was so cold nothing got a chance to build any heat. I will know more once things warm up a bit.

Just got the first lipo off the charger, it only took 2454mah. Runtime with this setup is giong to be crazy! Oh, and the other battery was 3.77v on every cell as well. 8 cells all exactly the same to the hundreth of a volt...not bad NeuEnergy!

[Brushless55]

sounds awesome man!!
great low temps a sweet runtime

[JPriami]

Congratulations glad it's doing good

Whoa! Possible 20min run?

[keithbradley]

Whoa! Possible 20min run?

I dont expect 20 minute runtimes full throttle. I got over 10 today with that litttle bit of battery power but the water was pretty choppy and I didnt have a resue boat, not to mention this was my first time out with this boat, so I was quite light on the throttle.

I can definitely see 10 minute plus run times at heavy throttle as a possibility though.

Did the water outlet worked as expected?

[keithbradley]

Did the water outlet worked as expected?

Yes, it worked well and was easy to see a stream coming out. The ony thing that didnt go as planned is that the rudder/strut assembly seems to shoot a streat of water up too, so I had to look and make sure there was a stream shooting up off the side where the outlet is, not just the middle where the rudder is. I will most likely try to put a piece of tape where the stream is coming from the rudder so it doesnt shoot up.

Curious, I've overlooked that stream of water , but thinking about it now, I wonder if there's a way to eliminate that and reduce the drag that's creating it.
