Speeding Up A Nikko - Island Cruiser

[Diegoboy]

Hi Sam,
That hull, as designed will not get you 15-20MPH. The hull will raise out of the water due to the prop angle. Once it get's speed and lifts out of the water, it'll fall to the left or right, depending on the turn you're in or the balance of the boat.

While you're throwing pics, how 'bout a pic of the transom?

Transom?

while you're throwing pics, how 'bout a pic of the transom?

Sorry Diegoboy, I might need a bit more explanation - sorry. What is the transom?

[Diegoboy]

No problem...
It's the back of the boat where the (if there was an outboard) motor would be mounted.

Thanks Diegoboy,
I am on it... be back in 5 mins

if I were to judge based on the motor wires...I would be surprised if that esc is rated for more than 10 amps(my guess would be 5a). a sticking point is the motor shaft size(2.3mm~3/32") trying to find couplers in that size can be a trial. a speed 480 would otherwise be my thought(you would likely need a new esc, radio/servo however that would work in your favor since the hobby grade units can be smaller than the stock units.

Ok here are the pics of the transom Diegoboy

Thank you Rex R!
So one option would be going for
* 480 speed motor
* New ESC
* New Radio/Servo

What do the other guys think about this potential package?

Cheers

[Diegoboy]

I would definitely go for it. If you give up, I'll take over...

Lets start...!

I guess an upgrade from a 380 motor to a 480 is sounding for the hull restrictions etc!

I have no idea about the electric part of things. So I will need some guidance please!

I believe the way to start is with getting the 480 motor? which one? anywhere online?

Regards

a dash of cold water before you get all 'gung-ho' on a 480, find out what size your prop shaft is(diameter). you might end up having to replace that as well.

Boat hop up

I think that what you want to do is fairly easy.At least for 15mph anyway. It will get bouncing rather hard though. Ten mph would be good and smooth.
You have a large boat so a good sized motor could be usefull. A 550 motor could easily fit in . I beleive the whole thing could be done for under $100 starting with nothing. You would need a different radio , a esc for the motor and a motor. None of which has to be new. A used hobby type radio off of ebay can sometimes be had for as low as $15. I bought a Traxxis for that all ready to go . A car type esc can be had for about $25 to $35 from Tower. I have a lot of 550 type motors to sell cheap .New for $3.50 plus shipping. I do make custom couplers to fit any motor to shaft size.
P.S.
Hi Rex good to see you on the computer

Hi Ned, small 'web' isn't it ?

Work in progress!

Thanks for the input! I am more than comfortable to go for one of those new 550size motor you have. That will be the first step then I build up everything else around the motor. i.e. esc, radio, etc. Perhaps keeping in mind that at the end I would like to have some extended running time of the boat not just 10 mins. Dont mind having to upgrade batteries if needed. As long as the esc and motor can take it and are aligned with that end result.

Couple of questions though before proceeding:

1. Not sure what couplers are - but my guess is the current motor has one. (See picture below). The motor is inside a black "jacket" that has holds the motor and matches the shaft ending with the motor ending.

2. If so, can you make that custom coupler to fit the current shaft for the new 550 motor?

Regards,

Sam
