Got a new proboat impulse 31 v2 need help

[waterproof]

Hi everyone.

I have bought a proboat impulse 31 v2 today and i have some question about the program card and other things about this boat.

1: i use 2x 2s lipo 30c, it dont go as fast as i tought.
Could this be the program setup?
The card stands on timing low inrunner motor.
I can also switch to timing high outrunner motor.
What is the difference? Dont want anything to get overheat.

2: What is the short plastic hose that came in the box?

3: the propel is very hard to spin around with my fingers. Is that normal?
I have a joysway/45km boat and that spins wery easy around when i use my finger. Maby its a lot more compresson in the proboat?
4: What is the wright way to connect the program card to the boat?
5: it is two reciever cable/ antenna cable from the boat and the small plastic hose have only room for one.

Thanks alot for any advice

As you are waiting for someone to pick up your thread, I like to tell you what I DO know, but I won't BS you with things which I don't know since I don't have this boat in my fleet, so to speak.
1, 2x2s lipo, 30 c is good, are you connecting them in series? I am sure you are, since this is a RTR boat, the factory connector is already made that way, unless you bought used. You say you bought NEW, so I assume you bought it brand new in a store . This then will not and should not happen.
The timing settings for inrunner and out runner are different, as you can see in the program card. You boat has an inrunner motor, set timing according to card instruction.
2, Don't know what short plastic hose is.
3, The propeller is hard to turn: it is normal, the motor is a 6-pole motor, it has tremendous cogging when you turn the shaft. Be glad it's that way, if it turns smoothly, the magnets are losing strength. 4 or 6 pole motors have more torque and they come with Proboat and AquaCraft. Most of the up grade motors you see here are at least 4 pole nowadays. Your Joysway may have a 2-pole motor which spins more easily with your fingers.
4, don't know how these V2 works.
5, The receiver has two antenna cables, you thread one into the plastic antenna tube, the other one lies flat inside the hull, this is Spektrum receiver, and some people even leave both of them inside the hull.
Hope that helps for the time being.

Thanks for good answers! Realy good help.

I have found out how i connect the card. Only need to know the first question in the tread :-)
Yes is rtr boat and its connected in series :-)

probably the esc is still in the "logartimic"mode : you will only have 80% power ( for beginners) ,i think if you change it to " linear" :100% power

do not change the timing

2x2s is not going to give you the big speeds (about) 55 km/h with the stock prop ( balancing is necessary !)

i use a 3s and a 2s in series with the stock prop : about 63 km/h

i could only change the settings from the esc when using power from the lipo's ,card did not work when using an external power source

[waterproof]

Hi. The esc is on linear 100% trottle :-)

What is the timing? It stands it is for 4-6 pole motor inrunner motor and high is for 6 pole or lager outrunner.
I have 6 pole but i dont know if its outrunner or inrunner.
The manual says that i could not switch to high timing if the engine and esc is over 55 celsius with the low timing.
Its also stands that it will give 20% more power and lower runtime on the battery pack.


I dont think its drive to 55km. 40-45 maby.

[iop65]

stock motor is an inrunner

40-45 is to slow for 4s with stock prop ( is it balanced/sharpened ?)

is something hot? lipo's/esc/connectors/motor?



what are the specs for the lipo's they are 30 c, but how many amps?

keep about 1.5 to 2 mm clearance between nylon spacer and strut

greace everytime

buy carbon prop if you can not balance and sharpen the stock prop , otherwise it will destroy your bushings/hardware and cost you speed

[waterproof]

The battery packs is 5200mh. Nothing on the boat is hot.
Everything is almost room temprature.

I drive with a joysway bullets and it beat me with 5-10km and that joysway should do 45km.

So because i have a inrunner motor, thatswhy i cant turn the program card to high timing?

I also got a couple of t spoon of water inside the boat arter running in 15 minutes in the water.

[waterproof]

It is still water inside the boat arter running.
After i dry the boat and out it up in the water its sees to came in under the emty plug or out of a small hole between the wood walls there it should be white glue like its on every other place on the wood, this is to the bottom of the wood box thats holding the reciever. .

Any ideas to what i must do?

[iop65]

i would leave the timing to the default setting

when using 4s you can prop up a 45 mm 1.4P is possible ( stock is a 40.6mm 1.6P)

you should also try to improve the handling and speed by making changes to the driveline ,or you might be lucky and it would all be perfect right out of the box :-)

sorry ,i don't understand what you are writing about the water coming in

[waterproof]

Thanks for answers :-)
Then i will not switch to high timing.

Where can i order bigger propel and how mutch speed will it give?
Sorry for my English, i can explane short. It leaks water but after i took grease on the flex shaft its been mutch better

What type of grease could i use when all the local shops is emty for marin grease?
I bought a universal grease that is water resistent and can work up to 125 celsius/257 F
Its also for use to big machines. Is it good enough grease?
How heat is the flex shaft after use?

[tlandauer]

Your grease should be good, as long as it is water resistant. The propeller you need should be balanced/polished/sharpened, OSE sells them but most of the time the popular sizes are out of stock. http://www.offshoreelectrics.com/pro...Balanced+Props You need to watch like a hawk, when it comes in stock and if it is something you want, just click "BUY", don't think twice!!
I like X442, X642, m445, m545, they are my basic props. You can also see if they have CNC aluminum ones, they are pretty good, but the ones I bought I find that I have to sharpen their leading edge more, it is kind of blunt compared to the b/p/s/ brass props.
To avoid water coming in your stuffing tube, you must grease your flex cable and sometimes put a piece of the same water cooling silicone tube over the motor end of the tube. See picture:DSCN0329_026.jpg
Happy Boating!

Thanks alot!

Im very happy with this boat. Its good steering.
No issue with it. Its the best boat i have own before

I will have some more speed, i dont want to try 6s. But will it take 5s with no problem?

[waterproof]

I have reed in the manual about timing.

Low timing for 2-4-6 pole inrunner motor.

High timing: 6 pole or more inrunner and outrunner motor.
High timing increases both motor rpm and current draw up to 20% increas to the low timing
Using the same battery pack and prop.
Run time will be reduced.
Use only high timing if the temprature not over 130F/54c

The manual says its high timing for both motor but the program card says Just high timing outrunner motor.
Should i still not touch the timing?

[tlandauer]

I don't think the "increase" of RPM of High Timing will give you any significant speed increase though. I agree with Post #9, the default setting should be a good compromise between all factors considered.

[iop65]

i have tried the 5s set-up
my thoughts where that the motor was not liking that : got hot rather quickly and run times are much shorter
it works ,but you have to prop down : a 40 mm 1.4 p is the max for a save set-up i think !

i bought a leopard 3674 1700Kv for 5s : perfect for this boat
speed is up (+/- 70 km/h, and nothing gets hot with a 40 mm 1.4P)
it can turn bigger props
like tlandauer is saying : cnc props are good ,just sharpen them a little bit

my english isn't good either ,live in europe
