electronic options for atomic arc hull 58in

[Alex Hogue]

looking to pick up an atomic hull from a friend just trying to figure out what i should do for electronics spoke with ose and the recommended the 5698 leopard
ill most likely be sticking with 6s but might do 8s what would you guys recommend for an esc? would a turnigy 180 cut it? im not looking to do any high speeds just
40-50

any other recommendations would be great

[Fella1340]

6s seems to me to be a rather low voltage choice for a hull this size. The setup would be rather inefficient. Most hulls that size are running 10s +, I am building a 50" P1 fountain scale type boat and will be using a 5692 size motor 820kv on 10s. I have seen big boats like yours running 6s, they used outrunners and we're getting a more scale like speed of 30-35 mph. Somebody with a lot more knowledge than me should chime in soon. I am newer to fe boats so my experience is limited. Good luck with the build, I hope you will post your progress here. We need more big mono hull builds happening on OSE!

You could use the sea king hv130a to leave some head room for higher volt cells down the line,
With the right kv motor and prop in the setup.

Hear you go read through all this info on that hull,
Or just jump to the last pages on whats going on.

alot of great info in that thread so basically if i stick with the stock 3 blade and run this motor "het 1170 kv motor" i can get a setup slightly faster then stock and still reliable
exact type of info i was looking for only downside not sure i like the short run times on a 6s pack and not sure i really want to share 2 packs out of my
550 heli for the boat might have to think about downsizing what i want for a boat

[lenny]

What packs are you using now for the heli ?
How much run time were you looking for with the boat ?

[Alex Hogue]

ive got 60c 5000 6s packs after looking at other boats ive been interested in ig 5 min is avg or less

shows you how much ive looked into boats seems they run times are about like my heli lol

[lenny]

When nut testing new setups for speeds and handling,
I do a lot of cruising when driving my boats.
Like this. http://www.youtube.com/watch?feature=player_embedded&v=ufp1qtvQias

For the boat you could just use turnigy 30/40c packs for sport running,
And having some fun.
If you want some good high end packs but not to bad on price,
You could look into these packs that Mark sells on hear.

I've been using value hobby packs in my heli stuff and cars haven't had them
Long but the lhs and a few other people I know have been having good results for
Awhile now I'll also have some 3s packs from my car I can run together

Does leopard make an equivalent to the het 92? And I'm assuming a 180a turnigy will cut it just fine or is the sea king 130hv a better ESC? Sorry for all the questions just want make sure I get everything set up right the first time

OSE has a TP Power motor with a closer kv to the stock ARC motor than the Leopard.

The only problem you'll have is trying to find a coupler to adapt the motors 5mm output shaft to the ARC's 1/4" flex cable. All the couplers I can find for 1/4" flex cables only work with 6-8mm motor shafts.
Bringing us back to the HET motor which will probably cost you over $200 for the motor/water jacket/coupler. And you'll definitely have to use a higher capacity and c-rated 6s pack or pair of 3s packs.
If your budget is tight just give the stock outrunner a try. Then upgrade later. Your ARR version is already setup for it. The boat really is a blast in stock form. Its quick and light. Not rocket-ship fast, but fast enough to keep a smile on your face. And the stock out runner will run just fine on less expensive 5000mah 25-30c lipo/lipos. And if you can still save a bunch of $$$ if you pick up all your electronics from Hobbyking or even find them here at OSE second hand from the for sale forum.

I have no experience with the 130hv, but the turnigy/seaking 180 is my favorite esc. Its one of the best bang for your buck esc's out there in my opinion and has been very reliable for me I'm many of my boats on 4-6s.

[iridebikes247]

If running the 5698 motor, the seaking 130hv will go up in smoke pretty quick imo. That motor can pull 250 amps on a spike I would get a swordfish 240. If anything get a tp 5850 motor they're 180 bucks with the cooling jacket.

[Alex Hogue]

You know that to motor is a lot more affordable I'm just looking for something that runs nice and reliable although I see you have yet to kill off a stock set up

As far as a coupler though my dads a tool and die maker so any of that stuffs not a problem
Hell I'd do it myself if I had access to his equipment

[lenny]

The seaking 130hv 5s-12s would let you run higher volt cells down the line,
If you wanted to.
Just do not over amp it with to much motor or prop and it should be fine.

I have a buddy the only runs sport running and he really likes the HW 130/180. He uses it in an AC 36" cat, and a 41" mono with 5692 1100Kv TP Power & similar Leopards on 8S 2P budget Zippy cells.

[Alex Hogue]

Tp4060 with a 130 and stock prop should get me to stock levels or slightly higher correct?

How do you figure say stock out runner transfer to x size in runner ? Ig its the motors options and sizing that the most confusing at this point

Hard to compare an outrunner to in runner by size. The make/build quality/efficiency can be so vast between manufacturers. So much of this is just your best educated guess, and learning from what other people have tried and their results.

[forescott]

I guess I just don't see the point of spending an extra $100 for the hv130 over the proven t-180. Pushing that setup over 6s would likely fail anyway.

[lenny]

Found one,
I am sure there are better one.

Page #3 of the thread I posted for you with all the info may give more light on outrunners.

[forescott]

Nice work Lenny! That is one strange coupler. Not too sure about soldering or gluing the flex cable to the sleeve, but if its done correctly it sure would be a nice solid connection between the motor and flex. No more grub screws digging into and distorting the flex cable.

[lenny]

Yes I have buddy that love's the HV 130/180A on 6s in his miss Geico,
And some other boat setups he is using them in.
Said it lets everything run nice and cool on 6s in the Geico.

ok so for motor options there is the tp motor or leopard

tp 4060 in 1130kv
leopard 4092 in 1050

both motors are the same size can as the het 700 98, given the tp is a little above stock im thinking it will be the tp motor with a t180

http://www.offshoreelectrics.com/proddetail.php?prod=tp-4060&cat=181
http://www.offshoreelectrics.com/proddetail.php?prod=ose-83005

should be all i need and a servo from the lhs and should have me under $800 for a boat thats ready to go and runs cooler then the rtr setup

[forescott]

Sounds good! Keep us updated on the progress!

Hey guys, what about the Turnigy T20?

http://hobbyking.com/hobbyking/store/__42488__Turnigy_AquaStar_T20_3T_730KV_1280KV_Wate r_Cooled_Brushless_Motor_USA_warehouse_.html

Looks like a Proteus copy from Hobbyking, was considering it for a 45" mono...might be an option for this?
