[Brushless55]

i just got my boat all set and i am going to install 8xl with 180amp esc what prop should i start? I am looking for 50-60mph?

I would start with the 42mm like at RCU that was posted and see how it goes

i am going to try to run 2 X 2sp1 5000mah 30c

I ran 54mph on 5S, 8XL, Octura x442. Mid 40s on 4S... 5000mah using 2S batts and 30C. I dont think you will see 60 out of an 8XL on 4S. It wont turn the prop you will need to get it there. Theres a HOTR on the forum that broke 60 on 6S w/ an 8XL.. but I would not advise that kinda running very much.

Oh.. and welcome to the forums

[jin429]

then how about a 6xl and would my esc be able to take that?

5s that's turning some Rs!
I bet that sounds real good though

That's asking for trouble in my opinion
over 41,000rpm on 4s will pull some amps
better off with the 8XL on 4s and see how that goes for you first
then bump to 5s on the 8XL for some short runs

last thing should i use bullet connectors on the lipo's? I have some 5.5mm handy.

[BakedMopar]

Haha you should hear twin 8xls on 6s.

that thing is killer

[jin429]

i have dean connectors on the lipos and 6.5mm on the esc. my dean connectors just get too hot.

deans can take some juice but the bullets can handle more amps and have less resistance
so you have 6.5mm and you want to use 5.5mm?

[jin429]

i want to keep the 6.5mm on the motor side and to connect the lipos with the 5.5mm.

It did, but I was scared to do it again. Just wanted to see what it would do out of curiosity. Ran 2 passes and that was all she wrote.
