Questions regarding Miss Geico

[Sharky]

Ok, i have scanned threw a few posts regarding the MG, I have seen a few ask some of the questions I am getting ready to ask, but i have not seen any straight forward answers..

Here is what i will be running.. The MG only has a offset rudder kit with breakaway screws and a 42x55 grim racer prop. everything else is Factory. I just bought a KV2300 WATER COOLED BRUSHLESS MOTOR WITH HOBBYWING 120A ESC. Which will be here on Tuesday.. I have 2 TIGER Lipo 5600mah 50C 7.4v 2S. and 2 Zippy 5000mah 45c 7.4v 2s battery's. I will be buying a few 3s battery's soon. I know the factory motor, esc. can handle 5s safely. Anyone see anything wrong with my combo's? any suggestions? I have also been looking at a dual rudder setup. But i did see someone on here said it was to much weight for the craft.. Ideas? I also bought a set of adjustable trim tabs.. Also looking into doing a dual water pick up. so everything will have its own cooling..

I am not new to the hobby, But i am new to Brushless.. so any help or advice would be helpful.. When replying to my posts please dummyfy your answers..

I have also been looking at the whole series vs par. wiring for the batts... The par. only seems to give longer run time.. which would give more speed??

I am not really gonna be doing course racing more Drag racing..

You're gonna run which motor on 5s? Dual rudders are kinda pointless on this hull. A proper setup shouldn't need trim tabs on a cat

[Sharky]

Either setup will run on 5s right?

I wouldn't run 5s on a 2300kv motor, that's asking for issues IMHO.

You dont need dual rudders or trim tabs.

What would you run on the 2300?

[driftah]

4s max

Why is it that you can run a 2s and 3s on a stock motor, but only 2x2s on a 2300??

Because the stock motor kv is a lot lower. Your target unloaded rpm is high 20k to low 30k, with the 2300kv your unloaded rpms will be over 40k which will lead to higher amp spikes and wear and tear on the drive components.

Unloaded rpms = kv * volts

So should i NOT run the 2300??

Why wouldn't run it... what's wrong with 4s or are you stuck on 5s.

I am just trying to learn. factory motor running 5s is fast... so I would think a 2300 running 5s would be faster.. no???

[dana]

Yeah it would be faster, but you'll probably smoke the motor.

[Diesel6401]

Like Dana said it will be fast until it blows.

Boating is its own world. Its not like a car just throw more volts to go faster, that mind set will get you into trouble. Boating has its own set of rules that if reliability means anything they should be followed. Sadly some newer members care more about speed in a short distance then building something reliable.

Myself I do cars, boats, helis and planes. I need reliability cause I simply can't afford to replace things based on bad decisions.

ok, so the first post has the extras i have... What combo would you go? factory motor with the new esc? the 2300 with the esc? ect ect?? 4s, 5s,6s?


What do you think about running the 2300 and the 120a esc on 4s?

[dana]

Stock 1800kv on 5s with 120 esc or 2300kv with 120esc on 4s
