New Proboat Impulse 31" Deep Vee

[wparsons]

The stock battery holder is designed to hold two packs, either two 2s or two 4s packs. It could work with a single 4s, but it'll be easier with a pair of identical packs.

I saw this boat today for the first time and dang I think it is the best looking RTR to date!

Mine arrived today.

One question:
The water-cooling tube runs rudder inlet -->BL motor-->ESC-->outlet.
Is it OK?

Run it to the esc first then motor.

Run it to the esc first then motor.

I concur with this... I always cool the motor first. The ESC doesn't usually require the level of cooling that the motor does.

and that's the way this is setup out of the box right?

I don't know... I've never had one "out of the box"... Someone here could likely tell you though...

Honestly, either way, it doesn't REALLY matter for 95% of the users out there. The ESC isn't going to pass that much heat to the water, and the water pressure is going to be pretty high. As long as all the lines are connected, I wouldn't worry about it too much.

I've checked temps time and time again and here in California with 75-80 degree water the ESC NEEDS to be cooled first. I've seen temps drop over 25 degrees on the esc this way on the exact same setup. Ideally each would have their own fresh cool water source.

just to give some props... I saw this Mono for the first time yesterday and I've got to say "WOW!"
to me the best looking and very solid RTR boat on the market right now
I'm going to get one soon as I sell a few things off first...

I'm going to respectfully disagree with this. This is assuming that the ESC will fail under the same temps as the motor, which is generally not the case. The motor will start failing approaching 150-degrees F... The ESC should be able to withstand much higher temps...

You are correct in that IDEALLY, each would have it's own fresh-water supply...

Darin I am a newbie to this, I just bought a impulse 31 and would like to run 6s on it, I have 2 3s 35c 5000mah. What would you suggest I change in order to do this?
New esc?
New esc and motor?
Any recommendations very much appreciated.

Have you run it on 4s yet? Why the desire for 6s?

[indrumbum]

i have run it on 4s, looking for more speed, run 6s for about 1 minute and it screamed, but i didn't want to chance burning anything up so i put the 4s back in.
Today on 4s I tried running x445 prop. quicker out of hole, on top of water more, flipped it on second turn. drained battery quickly. Have a prather 230 on it now, waiting for batteries to charge. After that I have a x447/3 waiting to be put on.
There just happened to be a nitro race in my city today so I was able to find some used props that were already sharp, and balanced for cheap.

Ran stock with Prather 230 prop, was really impressed with the speed increase, handled pretty well also.
I put on the 447/3, after I took off and made first turn remote control started acting wierd, I was bringing it back and it would not shut down and rammed into bank. Found that the receiver had got wet. Guess I will take the time to use hockey tape from now on. I will try that prop tomorrow but I believe the Prather 230 is going to be tough to beat. The only downside is the runtime on the Prather. It zapped the batteries pretty quickly.

[indrumbum]

waited several hours and reassembled, steering now working but throttle not working. How can I check to see if it is the receiver (mr200) or the esc?
