Its the octura x442.

Do you know your amp draw on 4S?
I also think my flex cable may have a limited life. I noticed it's bent in between the motor and the stuffing tube. I don't think that was completely lined up from the factory.Comment

Yes, I agree also. That is the best true offshore RC I have seen. (King of shaves).Comment

I'm not sure of the amp draw. I don't have a data logger. And my motor/stuffing tube alignment was horrible from the factory. I ended up grinding away at the bottom of the motor mount and even bending the little "L" brackets to line it up better. It's still not perfect, but much better.Originally posted by antslake View PostComment

Man, this boat looks great! Awesome videos too. I checked out your RC Groups link and there is some good stuff there too, as well as in this thread. If you don't mind, can you tell us what prop worked best with what voltage? That would be awesome.
Like all boat it seems to have its bugs but I already made up my mind and asked the wife for 1, for X-mas. She approved since I have a $60 off coupon from Tower, $289 shipped. I have plenty of Turnigy 5000 MAH LiPos too and I think to start 4S will be enough for the "small" pond near me.Comment

The octura x640 seems to be the best all around prop for top speed/optimum handling and stinger adjustability.Comment

I haven't tried that prop yet. I have a few more props to try, but was traveling a lot, and no time to sharpen them. Hopefully before the ice comes, I will get to it. The x640 is on my list. But that prop would probably only be good for 4s. I will be testing for 5, and 6S. My goal is to hit 50mph with the stock motor and speed control @60amps.Comment
-
Your gonna have to run an m645 to get that kinda speed. That 45mm prop is too big and will hit the rudder linkage without adjusting the stinger way down which in turn will give you a nose down attitude and scrub speed. If the 60 amp esc doesn't burn up first from too much prop. Good luck though!Comment

I was going the other way, down in size to reduce amps and bring up rpm's. I think it might just be a matter of prop work, but 6S and the right prop might do it. The 60 amp goal may be unrealistic, could turn out to be 70 or 80 amps. I was told the motor would blow up before the speed control. I've peaked the speed control at 88amps already on one short run. I think I've had it up to 47-48 mph already. It's not the way I would run it all the time, just a goal to hit. Most likely I will stay around 4S and 40-44mph.Comment

Why don't you do what I have done and get a turnigy H2136 motor in place of the stock one, this motor is good for 2-6 cells and should turn a bigger prop but as said you are limited by the hardware. I ran mine on 5s with a 90a esc and x640 prop and it was very fast, only had nod run as it's freezing in the uk at the mo. I have the 1600kv version but fightercat does the 2200kv and it's a straight swap motor.Comment
-
How fast exactly? I am using eagle tree to find out actual speeds. I can't see spending money, and taking out what is already good, just for a couple mph.Comment
-
I don't knw how fast exactly but from running 4s and x640 to the turnigy motor and 5s there is a deffo speed improvement. But at $20 from hobbyking u can't go wrong. I wish I had a vid for u.Comment
-
I recorded with the stock setup and x437/3 prop, going from 4s to 5s went from 38 to 44mph. But I was drawing 70 amps on 5s. 60 amps on 4s.Comment
-
That's why I recommended the turnigy motor, my esc died cos I got it wet so replaced it with a seaking 90a so both motor and esc are good for upto 6s. I would say the turnigy will be about as fast as the stock motor on 5s but it can handle it, venom only recommend 3s for that boat.Comment
-
Venom recommends up to 6s. I was working with there r and d guy about it. I have run it on 6s already, but I have the wrong prop on thereComment
