Purple Light Super Hawaii Knock Off build

[pompebled]

Hi Ken,

I've been reading along until now, you're doing great!

I have a tip to solder on the brushtab cooling pipes and the capacitors and the leads, without things fall of everytime you put a soldering iron to it...

Here's how I do it:

- I modified a wooden washpeg like in the picture, this enables me to clamp things onto the connectors on the motor and have access with the tip of my soldering iron.
- I make the motor connector strips curved, with a pair of round beak pliers, so it follows the rounding of the brass cooling pipe.
- I lightly tin all items to be soldered onto the connectors.
- Clamp the brass pipe in position with the washpeg and heat it quickly with a 100 W soldering iron (speed is important, as you don't want the entire brushholder inside the motor to become very hot, by 'baking' too long with a small soldering iron, causing the brushholders to loose strength).
- Position the capacitors, by folding one leg over the pipe, clamp and solder, don't forget to insulate the legs from the motorcan.
- Position the pre-tinned motorlead, clamp and solder.
- Solder the two remaining caps end onto the can.

Repeat it for the other brushtab and admire your work...

Regards, Jan.

Now why didn't I think of that before..arggg! I used to build plastic models and used clothespins all the time to hold small parts that I needed to paint. Next time I will remember. Thanks.

Purple Light Super Hawaii Knock Off build is COMPLETE!

Well I finally got the boat built. It took be long enough. It's tough when ya work and come home and have to deal with a wife who watches 5 kids and deal with the bs the kids cause and so forth lol. I will get picks up in the morning plus more details of the build.

Hi Ken,

Tell me about it...., some of my models are taking years to get ready, the quicker builds stretch over several weeks, some parts are made in an hour, the same part may take days, when you have to deal with other stuff than boating....

Pleas find the time to post some pics of your finished boat.

Regards, Jan.

Here is some I am going to put up the rest now.

[boater76]

Ok here is the rest. The boat was primered, painted with gloss Key Lime, and clear coated with Rustoleum Painter's Choice. It has Speedmaster Stinger strut, Speedmaster 21 rudder with h20 pickup, Octura .150 flex cable and prop shaft for 3/16th, Futaba 3003 standard servo, Futaba 75mhz am receiver, Jeti Jes 600 speed controller, OSE 700SC motor, cooling jacket, silicone tubing and Octura water outlet. It will be powered by 14 GP3300. The batteries were gotten dirt cheap from some auctions a couple of months ago. There were like 4 6 cell packs. I made 2 of them into 7 cell packs. I checked the packs after I built em up and was suprised of the voltage after sitting from the time that I got them til built up the packs, and who knows how long they were sitting before I got them. I checked them this morning and one was over 7.9 and the other was over 8.8 I plan to tub test today and go boating tommorrow.

I tub tested the boat and no leaks. Tommorrow I will take it out for the maiden voyage.

Hi Ken,

That looks impressive!

Nice watercooling on the 700.
Did you make sure the cooling slots on the motormountside are free, circulating air through the armature is cruicial.

The 0,9V difference between the packs could indicate a cell (or two) on the point of failure.
On the other side, the packs may just need a few cycles to get up to full power again.
If you can, charge the packs as they are used, connected in series, to prevent the packs from drifting apart ' Ah wise'.

What prop do you run?

Good luck on your maiden!

Regards, Jan.

I ran it today. It seemed like the packs died fast. I didn't have the boat at full throttle much. It seemed like after a couple of minutes it slowed way down. I started with a 40mm carbon prop.

Sadly, that's typical for one or more dead cells.

If you have side by side packs, it's easy to pick the dead ones by using a volt meter on each individual cell after the pack has been run.

If the Voltmeter doesn't show it without load, connect the 14,4V pack to a car lightbulb and quickly measure every cell, the weak ones will almost immediately drop in Voltage.

Remove and replace.

Remember to give the 'new' pack an equalizing charge of 1A or less before running it.

WHERE DID YOU GET THIS BOAT??? i need to know. i want one. link?

[boater76]

I got mine off of ebay.

Will need some trim tabs and turn fins. My buddy has a purple light as his first. We used it as a learning boat. I still love my Super Hawaii, it handles way better with them. C

[boater76]

Been awhile since ive been on here. I finally got the boat out for the second time. I got a couple of electrifly 3600 8.4v packs from tower hobbies. Boy did that thing fly with new batterys. My hatch got blown off. My dumb fault. I didn't tap the hatch on all the way. The only problem I have is water gets in and dont know where. It is alway in the back of the hull.

I have had the same prob with mine. It comes in up by the motor. Im sure it is the cooling jacket. Too much pressure. Try running your cooling lines out the side and dont hook up your motor cooler. Run it 2 laps then check for water. Good job on the build. C
