NKOK boat surgery

Well i tried the yellow 27 mhz and it kinda sucked. The reception was bad and the motors pulsed. The red 49 mhz is pretty nice . Im pleased with it.

So, i decided to tear the yellow apart. Cabo is right its plastic welded together but with an xacto knife and patience i managed to break her open without to much damage. The motors are sealed in the white motor hull thingies but they are easily opened once removed from basic hull. Motor is typical bit motor but hardwired with 2 wires plus a ground wire soldered to the casing. A bit motor fits in nicely, but im not sure how you would solder wires onto a bit motor to get the same functions as this motor. Any ideas????

also it has 2 batts, havent craked open that area yet to identify type etc. bit i think you can easily add at least one more and prolly put it in the rear of the boat between the 2 motors. Not much weight but if anything it will lift the front and give it a race boat look. Im too busy to tinker with it right now but these ar ejust preliminary findings.

beat me to it ez - my yellow boat just died the other day so I was gonna do surgeory and open her up, glad you did first so I know what I'm getting in to for sure!
thanks for the pics and explinations man!

do you see holes near where the charging port would be on the inside of the boat? like water could leak in there or the switch right? I'm thinkin that's whay fried my boat.

ahhhh i see the making of a 4 cell ,,,,,,,,, think iam gonna cut open my sons boat lol..... he will never know lmao... my red boat s motors pulse to ones faster than other ,,, but i like the boats tested um in the pond wow hit a little ripple they go nuts lol ,,woundering how they would go with m/s motors /////

oh well fill us with more info thanks for the pics of the inners ,,,,,,

by the way the suv is pretty fast it must be dual cell to ,,,

hey cabo when u making me a truck

ya i just cracked open mine tonight cuz my kid busted the antenna off. those disc wafer resistors connected to the motor circuits limit power so i cut them off and now i got a nice performance boost. one night soon ill resolder the antenna and seal her back up. what yo guys gona use?

Why not just use a silicone sealant/caulk like for a shower door?

SuperFly - I think that stuff is going to be too heavy and go on un-evenly, we're gonna have to make sure whenever these boats are put back together, we don't screw with the boyancy (sp?)

Hog, I've been thinking about this for some time now.
I found this glue that is like super glue in the sense it goes on clear and thin but is strong and water resistant.
The really cool part is, you put on the "glue", but before it actually adheres, you have to put on "activator" - so that's a nice feature... but the really cool part is it also has a "debonder" so I can spray this on and end up taking the boat back apart if needed, without anymore cutting, etc.

So tell us Cabo, what is this miracle glue called, and where do we get it?

i think im gona go with jbkwik. did you guys cut out those resistors?

Post by **CaboWabo** » Fri Jul 18, 2003 9:28 am

I'll have to check when I get home - but it's a little kit thing - its pretty cool
and I got it at a wood shop of all places!

how fast do you think the boat would be with 4.2's and a mosfet mod
(ph2t hint hint)

how do we figure what th epcb can handle, volts wise?, without burnin it up??? just assume same as bit ( around 5V)??

ya i wouldnt ad more than another one or two cells. remember its gona effect how it floats if its too heavy. trust me removing those resistors will give you a major boost.

I was thinking of doin the laymans battery mod and doin like 4 batts since that would be about same size as those 2 in there. Just curious what i coul dadd

well they are a cheap 10$ toy so maybe a 4.8v boat would totally kick ass. i only got one tho so im not gona go overboard.
