[8D]Hey guys and gals,

I am selling off my big Gasoline RC boat cause its just way to big and fast for my lake. I am wanting to get a nice electric one, well actually 2 so my son and I can race

I was wondering what is a good electric boat to get, Im thinking a deep V boat. I want one that you can modify of course!! My sons will stay stock till he gets good. Not sure about budget yet so Ill take any. I am hearing that the brushless ones are good but dont know the pros and cons with them yet. I havent had many electric boats and havent had one in a long time, so any help will be much appericated.

Thanks everyone....

Then the SuperVee 27 is your perfect choice!!

Thanks for the info. Ive been told that boat is good by a few people, so I guess I should lean towards that one. Thanks so much and still would like some more recommendations unless the one mentioned above it just the best period!!

Thanks , Miike

There's the Black Jack 26 Brushless that's fairly new:

I have one and I think that it's a great start. I'd say get the SV27 or the BJ26.

There are two other proboat models that are very new that I wouldn't recommend getting yet until someone gets one an tells us about it.

Thanks Bob,

After looking at the electric boat forums for alittle I have decided to just get the Super Vee 27. Seems like everyone is happy with them and they sell good hop-up parts for it . Thats something thats right up my alley!!!

Thanks for your help.

Alrighty then, you'll be needing the following to start out with:

This is assuming that you're going to get one for your son also.

4 of these(two per boat):

1 of these(2 would save time):

1 of these:

I've used all of these things before when I first started RC boating and it was a great start.

For now I would stick to the stock prop and then ask around for an upgrade.

If you're willing to spend some big dough you might get 4 pairs of packs to double your race time.

If you plan to race with your son you might wanna get two different colors so that you won't have radio issues.

Yes I will be getting one for him also as long as hes a good boy and does good in school of course

Now as far as mods, how do I make this thing faster?? Bigger motor and/ or batteries?? Thatll be for my boat of course!! My son will need some practice before we start modding his boat

RC_Bob

To do the easiest thing I would start out with a bigger prop. This is the one that many have used:

needs balancing and sharpening.

Another way, which is kinda risky, is to use 7cell battery packs. I wouldn't go this way to start out with.

That prop, and this motor:

Make a nice upgrade that you can get away with running the stock ESC. If you just run that prop on the stock motor, you may be disappointed with the amount of cavitation you get.

The main limiting factor with the SV is the ESC. If you intend to run lipo packs, you will need to add a low voltage cutoff. Also, if you want to run 7 cell packs on anything but the stock motor/prop combo, you will risk frying the ESC. Don't get me wrong, the ESC is very reliable, but it has its limits.

If you add 2 2S lipo packs to that prop and motor combo, you should be pushing the low to mid 40 mph range (a good running stock SV on the stock prop with 6 cell nimh packs is generally around 32-34mph).

These trim tabs are pretty much a must have item too.

Oh yeah, and you may want to consider swapping out the radio as one of the first things you do. You may get lucky and have no glitches, but that's not very common.

Thanks guys for the help...

I am also wondering what is the difference (pros and cons) of regular VS brushless motors. Ive read alittle about them but Id like to hear it from actual people I can talk to and ask questions to!!


Again, Thanks all

ALso, how much run time do you get out of it? Im not that familiar with this brushless stuff....

RC_Bob

I know a little bit about brushed but not a lot.(below is right out of rcboataholic.com)
Brushless is better because:
* Less radio interference since there is no brush arching
* Less resistance in the windings since there is no brush to commutator interface. Additionally you can have thicker wires (lower resistance) than a brushed motor of equivalent size. Both of these result in overall lower resistance and higher efficiency and torque
* Lower friction loss since there is no spring/brush pressure and drag on the commutator.
* They are efficient over a much wider range of power. Efficiencies range from 75% up to nearly 90% depending on style/brand.
* Better cooling since the heat generating windings are against the outer case and not buried inside.
* No springs to change, no brushes to replace, no commutator to cut.

As for run times, they will greatly vary depending on stuff you use, but usually the run times are 5-10 minutes.

WOW, 5-10 mis is SHORT!!! Thats why I liked the gasoline boats!! 45 min run time is much better!!! I guess Im going to have to get alot of batteries and some quick chargers!!! Id like to invest in a nice charger also. One that can do 2 batteries at a time and can plug into AC power as im only going to run this boat in my backyard.

Thanks for the reading materials!!

Get max amp 2s 60-65c 13500mah lipos for about an hour of run time depending on your throttle habits. You will get atleast 45min with a pair of those. www.MaxAmps.com i think. Gasoline boats are hard to maintain and are a lot more expensive. Want runtime? go with nitro boats.
A charger that can charge two batteries? i thought i saw one, ill find out and tell u.

carwen

hexTronik Balancer/Charger Dual Charge Capable
Available at Hobbyking for like 30 bucks

siberianhusky

Confused! Isn't this 2 1/2 years old?
And LOL that charger has a max of 2 amps! It would take hours to charge your batteries with that thing! Thats probably 2 amps on 2s only, probably half that on 4s, does not even tell you how many watts it is! If it puts out 1 amp for 4s and you have to put 3000 mah back into a battery it will take you 3 hours!
There are much better chargers available from HK!
