sprintcat (copy)

[ozzie-crawl]

this build wont be finished for acouple of months but thought i would post some pics anyway (off my phone)
planned setup
motor mount by peter zicha
motor 580 9-10l
esc himodel 200 a
batteries 30c 5000 6s
hardware speed master

That mount looks killer. I might have to get one from him on my next build.

[ozzie-crawl]

yes he does an awsome job. just trying to build a clean boat but couldnt find a decent mount for the 580l motors and peter was kind enough to build me one to suit
here is some pics of my phone there a bit crappy and dont do the mount justice but give you an idea

[Raydee]

I am really curious to see how that Himodel 200a ESC will hold up. For $50 I might grap one or two to try out and throw a nice micro fan on the top of them.

[ozzie-crawl]

i have ran a few himodels from 4-6s and only time i have killed one is from water (60+mph flips)
have pulled some fairly high amps threw them on both 4 and 6s and they have held up well,i usally limit my runs to 1-2 minutes tho
but the escs are not water cooled either
my mate had one in a boat running 6s that was pulling over 160 amps none water cooled and was okay for 2 minute run times

Scott,

Where did you procure the cooling jacket for the 580L?

Thanks,

Ray

well from what I have learned if your going to run 6s in this hull than around 1250 kv is the way to fly

that would make the 10t your best choice ....

I ended up getting a 1527/1y which is 1250 kv

[ozzie-crawl]

yea they 10 turn would also spin a decent prop, keep us posted on your rebuild will be interesting to see what it goes like with the nue
cheers scott

some better pics

That is a very nice motor mount.
I figure that once you go up to the larger format of motors like the 580 then big mounts are needed, particlarly at the rear (bow end) of the motor.

I see you are still using the large brick boat stand and not the more moblie polythene one on wheels.

[ozzie-crawl]

the brick boat stand while rather heavy is for future development as my boats seem to be getting bigger each build
i figure by 2012 i will be up to 1/2 scale and may need to add more bricks

I am new to the OSE Forum and to electric boats, however, I have built 5 different Sprint Cats and raced them extensively. I am out the racing now but want to build and electric boat for "sport" running. Of course, my choice of boat is the Sprint Cat, at least I know the boat and it's setup. Can anyone tell me how the 580 motor conpares with the Neu 1521 Y1? Good luck with your build.
