The newer Shultze 40.160

That makes a big difference. Now you are on the borderline case and you will not see 3 minutes of WOT runtime.

yeh thats what I was worried about.... I won't run wot the whole time.... but I do have enough matching cells to make 8s2p 10000mah so maybe I need to add battery tray length....lol..... anyway its cat-bois old cat he never ran that I bought off the swap shop a couple months ago.... what speed do you think it will be good for speed wise on 8s with the x457's? thanks tyler.... immensly as I know you have experience with the big boats!!!!!!

At least set the boat up that you can add 2P per motor. I am hitting 65 on 8S2P running a X460 prop in a conquest. With twin power and the long skinny scale hulls i would expect you can see 72-75 pretty easy. With 2P you could probably run a X462 to hit 80. Want to go faster? Take a X665 and cut it down to 60mm and you'll probably be doing over 90.

Twin 2215's have a lot of potential with good controllers and batteries to go really fast.

Many of the European cat guys are running similiar power systems in that range, but none are probably running for 3 minutes on 2P.

Many thanks for the info tyler!! sounds like I am going to see 60 or so with my 8s1p setup.... I will only run for a couple minutes with that..... and I will add some length to my battery trays... just stinks because Sandy (Cat-Boi) meticulously made the carbon fiber battery trays and they wont fit 8s2p 10000mah for each motor (4 5000mah 40c turnigy packs each sides) but I have 16 40C 5000mah 4s turnigy lipos that I bought for this project.... I go a little lipo crazy.... thanks for all your info!!!!

By the way those x455 non counter rotating aren't the props I am using... just had them on there for looks while the boat was sitting around collecting dust!! LOL...

Try it 1P with the current trays and see how long the run time versus speed is. If you want to go faster or run longer, you need to go to 2P.

Do you have pics of the inside or a link to Sandy's build?

I also have enough Brand New Poly RC 35c 5050mah lipos to do 1p of 9s, or 10s as well.... as I bought 2 each of 4s, 5s, 6s for this project from pat at RCLIPOS as well... like I said I went a little lipo crazy as I am sure many do....

Thanks for the link.

If you can run 10S1P per motor you will have lots of fun. I run 10S1P 6500mAh Neu packs for sprint racing with a X457 and put on a good show. That set-up ran a 23.001 second 2-lap time recently.
