HK 41" Vanquish with CC 1717 1y 1580 Kv on 6s 2p I hope

[tryinotocrash]

So Hello. I have some of this posted in another thread looking for help and advice,I am new to FE boats .I built a couple of nitro boats 20 plus years ago, I do fly electric so not ignorant but this is all different. So I see Diesel has this same setup and has it for sale. Looks good.

So I have several props to try this weekend I currently have the T180 esc in there until I figure out how to program or use the fighter cat with my current setup. I picked up three graupner props to start with until I figure out a good size to start with. They are 2317.45, 48, and 51.
Any and all help is appreciated. Thanks in advance.

I'd run an x447 or an x448

[tryinotocrash]

Yes one of these are really close to the x447. I just bought the cheaper ones to try and see before I buy some good ones.

[Make-a-Wake]

Thats the way to do it, test with cheapo's and buy the good ones that will work.

You may have to straighten the bottom out to get it to run correctly. Not a big job but an important one.

just my impression, but sounds pretty high kv for that size hull... I am running 10S2P on a castle 2028 in my 45" AM XXX hull and pulling 180-200 amps continuous...
your the esc sounds marginal to seriously not enough. not sure what your goals are, but this combo sounds at the upper limit of "just about to smoke"...

[tryinotocrash]

Grazacind can you explain just a little what you mean by straighten the bottom out.
Jesse J yes it is on the high side but I have seen several this size with a similar setup different ESC run in the high 50 mph range. I hope to keep the smoke in with prop choice ;-) keep em coming please..

[Make-a-Wake]

With an x448 he'll pull around 130a constant.

The bottom most likely will have a hook to some extent. Using a good straight edge like a metal ruler lay along the from the transom forward. Slide the ruler the ruler sideways towards the gunwal see how flat the bottom is.

If you have a dip then there is hook in the bottom. Fill it in thin stages then sand, then fill then sand, then fill and so on. It does make a big difference having a straight bottom.

on the fightercat esc, if you have not done so already, order the programming box from them and be done with it.
once it is hooked up to the ESC, it takes about 15 sec. to program.

A word of caution: run your boat first to see how she handles, regardless of how the bottom looks. I have seen examples where hooks were removed and the boat performed much worse. My Titan 40 is not "supposed" to have a hook; it does and it runs beautifully!

I'm actually not running (or planning on running I should say if the boat doesn't sale) 6s2p anymore. The amp draw was too high. With a x447/3 and Ice 240 w/ data logging the spikes where more then I first thought they would be (above 200+). I recommend not going that route and def not with a 200amp speedo. When I get off work I think I have the data-logging saved on file (not 100% sure but I can check). If the hull doesn't sale I will run 5s2p. With your esc I believe 4s2p is just fine and maybe (not sure) 5s2p (would be pushing it)..

[tryinotocrash]

Cool thanks. I do have 2 two cells an 2 three cells I was going to hook up and try it with as 2 5s setup. You think that would work? They are all 5000 mah batteries. I saw your video. Looks good. I do have the fighter cat 200 amp.

[tryinotocrash]

Could someone recommend a motor for this setup for 6s 2p ? Be specific please. And will iy bolt up same as the 1717 castle ?

Try a leo 4082 1600kv or 4092 1480kv.
I prefer the 4092 1480kv.
