wich motors for this setup (41" Zonda)

[Mecka1990]

Hi, now the question comes wich motors is better for the 41" Zonda cat in Twinsetup

2x Swordfish 200amps plus esc
2x counter rotating props (40-45mm)
2x 5s 5000mah 50/100c


they must be 4082 leopard, but wich one, the 2200kv 1.5Y or the 2000kv 4D? (dont want to burn my esc´s, but want to drive the boat like a lightning, max speed)

Have you tried the motors that come in it? You should run those first. If you're running 40-45mm props tehy should be fine, unless they are very poor quality.

[Mecka1990]

thats the problem, im scared of driving the 37mm that comes with them, what if they destroy my esc´s -.- i think its better i put the 37 in a another cat (rescue boat haha) and the leopards into the zonda. dont want to destroy my esc´s or motors.

running @ start 43mm props that comes witht he zonda, ordered 45mm and gonna try them on the leopards with onboard esc and motor heat controll.

what you think about that?

[Mecka1990]

and how i read, sss are poor quality

[dana]

Either one will work...

[Mecka1990]

is there a speed differenc from 37mm to 40mm? if the kv is the same and both got let me say 2Y, there is a speed differenc?

[dana]

Is this your first Rc boat?

[Mecka1990]

Is this your first Rc boat?

no, but my first catamaran twinsetup and first motor chose, the motors i have buyd before i find in the forums (like the one i buyd for my spartan, 4082 1600kv 2y, want to sell it in austria somewhere for only 100 Euro, dont use them once -.-)

[dana]

I would just buy two 4074 2200kv. I don't think getting 4082 will gain you anything over 4074. You could even go with 3674 Leo. You have a twin why you think you need two 4082?

[Mecka1990]

i just want to put max speed in it with 5s lipos, and in the other threads eversyone say go for 4082 leo, so i want to do so, but wich kv i shoud take, 2000, 2200, Y or D? i dont know -.-

[dana]

For 5s I would go 2000kv

[Mecka1990]

thank you much dana.
did i need capacitor banks for the 200ish plus esc?

[dana]

You're welcome. I don't think You need cap bank

[Mecka1990]

ok, thats all for now, cant await to get the boat, 10-12 working days hor said, thats for me like 12 years :-p

[Mecka1990]

how much milimeters i need from the stinger drive to the drive dog on a flex cable/shaft?

[dana]

Those square drive cables?

[Mecka1990]

ehm, no, on my spartan, 3/16 flex with 3/16 shaft in a 3/16 stinger, want to repair my spartan, ordered a new esc from steven right now :-)

[dana]

You have ALOT of questions about a boat you don't even have yet. Why don't you slow down and just wait to get the thing.

[dana]

3/16 gap

[Mecka1990]

thats another boat, hahahah, thats the spartan with the flex problem, i lost my last flex because i only let 3-4 mm to the stinger from the drive dog, i think when i get speed and the flex starts to roll around it gets smaller and so i lost it, no room for flexing or how it was said.

[Mecka1990]

what you mean with 3/16 gap? my english is not the best, and translater translate this: 3/16 gap (head->wall)

[Mecka1990]

a 3/16 gap is 3/16 of the widh from the flex? so about 4-6mm?

[dana]

Make gap same width as flex cable size ok?

[Mecka1990]

ok. thanks :-)

[dana]

[keithbradley]

If a 3674 4 pole motor won't spin a 43mm prop, I would throw them in the trash, not another boat.
