Siggy's Swiss Model Powerboat

[Anbjorn]

Yeah,
I have to agree with Tyler here. Nice build.
I would suggest to use some kind of current limiting device to prevent the huge spark and damage to the bullets.
Here is a nice little device that I will use:

Not sure if it will handle all the caps you have there but....

Nice work Siggy,

Be sure to wear some welding gloves with plugging the battery :-) , all those caps are going to make a good POP!

A simple 5k 1/4 ohm resistor with aligator clips also works. You can double them up if you want to charge it quicker, but I have never had a problem with that set-up.

Hey,alligator clips so you only need one setup instead of on every battery.That's thinking,great tip.

Thanks! Looking forward to a long-due vacation. Let's do the Full-Throttle SAW Run in Manila.

With the excellent workmanship and Carbon Kevlar Hybrid Fibre, do I really need a spare?! But surely a GREAT sight to have 2 or 3 swiss powerboats running in tandem. :)

Here is a full mock-up, with the Punisher67 Mount.

Sweet! Can't wait to see that in Manila! Wish I can make one of those someday! Hehehe! Pero kahit tira-tirang hull lang nyan pwede na! Hehehe!

5k 1/4 ohm? 5k ohms seems like alot and i dont think 1/4 watt is enough
there are 10 ohm 2 watt resistors available at fightercatracing.com, they work well.

[RaceMechaniX]

It only takes several seconds to charge the caps even with the 5k resistors, so I don't mind if it's 1 second or 3 seconds.

last time i used a 1/4 watt resistor it blew, could've been something else but just making sure, you know best

Hello Siggy,

the ESC mount looks beautiful. For the setup: Do you want to run 2x 5S or 2x 6S? I also wish you a succesful maiden run!

Best regards,
Manuel

Appreciate much your recommendations and help. Punisher67 did a splendid job, indeed.

I was told 5S for for the pair of 1950/5 Hi-Amp WK LK 2508KV and x457R/x457L -- cut down to 50mm.
Would you recommend I try a 6S, as well.

That ESC mount is sweet!!They look way better in there stacked.

Stacked is the only way to get the pair of SAW Monsters securely fastened.

Nice work Siggy,

Thanks Tyler for the reminded and compliment. Both ESCs have a small plug the anti spark device. It also is double motor and battery cables. Each battery cable have twin plugs, I suppose to be able to plug 2 packs in parallel. The ESC were serviced by Schulze 05/09/2011 getting new caps and software, I was told. I will check on the anti-spark device.

Thanks Anbjorn for your apreciation. HansPeter gets all the credit for building the custom hull and personally installing the hardware, making sure all is aligned the way it should be. I can already imagine the sparks to be just like a welding machine :)
I saw something similar to the link you sent used by this guy ...

Great idea, I shall do as recommended. THANKS!

Agree! A very practical yet effective recommendation. Tyler is the Man!

Looking forward to having a GREAT time. We might need a rescue boat, if there are plans to push hard. :)

Thanks for the reconfirmation.

Then, 5k resistors should be plenty. Thanks again.

That's quite scary. Can be anything -- most likely a short circuit, somewhere.

[Boaterguy]

possibly, they were hk esc's so they probably contributed

That also is possible, I agree.


Here is my 5A Voltage Regulator (with a somewhat "scale-looking") Fail-Safe Switch.

With the Fail Safe Key Detached - 5V-6V Power to RX is Active

With the Fail Safe Key Attached - Power to RX is Cut

Hoping that this Fail Safe System can help minimize the chances of injury when working on the propellers or during Rescue Operations.

My No-Frills CF Lipo Battery Mount. (4) Velcro straps secures the pack to the mount. Lipo positioning is adjustable.

I used Marine Contact Adhesive to glue the CF mount to the hull.

[Boaterguy]

maxamps packs? please don't tell me you'll be running these.

[Siggy]

maxamps packs? please don't tell me you'll be running these.

Why what's wrong with using MaxAmps? (aside from having Negative feedback of being over-rated and overpriced? :)

[Boaterguy]

haha, well aside from that and the fact that it's true and they think packs that they say can delver 950A needs to be watercooled, they are great!
run them if you want, I don't think anyone has actually tried them in a boat.
