Hello, I'm new to this forum and I'm looking for some help. I purchased my first boat and I am way out of my wheelhouse. It has a stock motor and an 80 amp esc installed and I will be running two 3s 40C packs. Just for starters, where should I start for a prop? I am looking for speed more than anything, I have a habit of really pushing my toys. I am sure I will have ore questions but this is where I want to start.

Welcome! There is tons of great reading here at OSE and in this section on the Motley Crew and Lucas oil. Many veterans have shared different setups in regards to motors, batteries, etc.
Stock the MC has a 60 amp esc, so yours has been changed out. Also, I haven't seen many run on 6s, mostly 4s or 5s. Getting the correct setup with motor, esc, batts and prop will yield top speed and a setup that is consistent and fun.
Good Luck and have fun! -
I saw one run for the first time yesterday. I was pretty impressed. I wouldn't run 6s on the stock setup. The one i saw yesterday was on 4s and 5s. I think on 5s you'll be impressed. To run 6s I think you'd need to upgrade your esc for sure and I'd recommend not running that motor on 6s much either. Try it on 4s and 5s, when it's adjusted correctly, it's a pretty fast boat. On prop, I'd say something like an x64232" carbon rivercat single 4s 102mph, 27” mini Rivercat 92mph, kbb34 91mph, jessej micro cat(too fast) wasComment

The esc should be fine and the motor...... Well there is always upgradeable ones out there.... :) I will do some more digging on a prop I guess.Comment

I've had good luck with the Grim Racer or GR 42x55 prop and the octura m445 prop, both sharpened and balanced, which makes a big difference.Comment

Thanks alot pistol! I will give the occur a a shot. Also i think I will bite the bullet and upgrade the motor right away to the leopard 3674 1400 kv. Anyone else have a similar setup on 6s?Comment

I'd be wary of an 80A esc on a 6s setup. That will be ok on 5S. For 6S I would really think about a 180A ESC like a seaking unit, that would be bulletproof. If you do some research you'll find many many many cases of Blackjack and Impulse owners burning up their 80A ESCs on 6s.

What if we kicked it down to 4S? running the same 80 amp esc and going with the Leopard 3674 motor at 2200kv backed with 2 5800 mah 40C Turnigy batteries?? Should be 200 amps available and swing that motor at 32,560 rpm. I would think that would make for a pretty quick yet safe setup. But what do I know, if I had all the answers I wouldn't be asking the pros!!Last edited by zmyhre; 02-02-2015, 10:00 PM.Comment

i had a lucas oil
stock motor
43mm cnc 1.4p prop
90a esc
5s
easily 80km/h
even used the stock 60a esc with this set-up once: no problem
but keep in mind that the stock esc has a lvc set at 12volt so lvc is useless at 5s !
loved the boat,handled really wel for a rtr!Comment

How do you run 5s in a boat? Balance wise?Comment

These are nice solid ESC's for an RTR... http://www.hobbyking.com/hobbyking/s..._Boat_ESC.html - lotta guys on this forum run them, myself included.
There out of them at the moment, might wanna keep an eye on them to see when they get back in stock, then get a couple.
One thing I have noticed, lotta people say if using 5S / 6S with those ESC's, it would be wise to either use a receiver battery pack or a UBEC - instead of the built in BEC to help take a load off the ESC.

Suggestion: read the reviews & comments on the HK website - I'll let others do the talking, don't want to get accused of bashing
Does this look familiar??... http://www.skyrc.com/index.php?route...product_id=111 -- D/L the manual & open it with Adobe Acrobat reader
Here's the other 1/2... http://www.skyrc.com/index.php?route...product_id=112 - got error msg when I tried to get the manual
HK website - Files Tab->manual -- compare it to the manual from SkyRC - notice anything??

Good luck...

I decided to go with the Leopard 3674 2200kv motor and the Seaking 180amp esc. I backed them with (2) 2S 5000 mah 45C Zippy batteries. I flipped the motor mount backwards to clear the bigger motor but it is now looking like I will have to trim the flex and stuff tube. Has anyone else threw a bigger can inside using the stock mount? Are there any tips on what did/didn't work out for you?Comment
