 Hi captains,

I ended up working on the boat all day and night. I finally stopped working on her at 1 am. After I glued the air exhaust cube in place I continued onto other items. I removed all the water tubes aft and am getting ready to purchase new tubes in the correct size. The size changed once I bought the water pumps. The nipples on the pumps were too small for the tubes I had in place so smaller ones will be added to ensure a proper fit. 

Once I removed the tubes all the way aft I filled in a pair of water pickups with epoxy and on the bottom of the boat filled and skimmed over the that pair with epoxy. Now it’s as if they were never there. The pair that I chose to eliminate were the ones just above the props. The removal of the pair of water intakes eliminated four water inlet tubes so now there are four left, one for each pump.

After that I moved on to adjust some of the contact springs so that the superstructure fits better.

Later on I decided to scratch build and install the ducts for the engine room intake fans. I made those from basswood frames and a balsa bottom plate and they were coated in epoxy and later sanded smooth. Once they were installed they were painted red which is turning out to be a great contrast from the gull grey interior.

After those were installed and painted I decided to get a jump on the sump pit. This is part of the rectangle box assembly that is around the stuffing tubes, shafts and couplers. Coming from the rectangle boxes will be water tubes that feed into the sump pit so that any water that leaks from the stuffing tubes will drain from the rectangle boxes and into the sump pit where it will be bailed from the boat. The sump pit will be located between the aluminum receiver box and the servo/switch box along the keel. It is important for me to finish this before the next time she sees water because I had a few minor floods in the engine room because of the stuffing tubes letting in water. This should stop that from happening.

The sump pit was built around a Robbe automatic bilgepump. It was made from balsa to save weight and was heavily coated in epoxy, cured, sanded and recoated. Tonight I will sand it, give it a final coat of epoxy and afterwards paint it red and get it ready for installation. At this point, many scratch made components in the engine room will be painted red. It really makes those items pop when you look inside.

The final item that needs to be finished inside the engine room in the short term is the exhaust ducts and the tubing between the fan cube and exhaust ducts need to be connected. Then, the engine room door will go in place which will be sealed shut so that water can’t pour inside and overtake the room.

In between working on the sump pit I also made adjustments to the rectangle boxes and painted them red. I still have to make the lids for those boxes so that when water splashes out of the stuffing tube at thousands of rpms it is contained inside the box. One final note with that, when the lid is removed from the rectangle box there will be an aluminum splash guard in there. It will be made from a thin aluminum soda can and it will be half round lining the inside of the box to further keep the water contained so that it drains and doesn’t leak out. The lining will simply lift out once the top is removed.

I have been putting a lot of thought into how I’m going to tackle mounting the superstructure. The superstructure when pushed against the hull is a snug fit but when I let go it still seems to ‘do its own thing’ and come up slightly in some areas. So mounting it so that it is tightly flush with the deck has become pretty important. It will not only make the boat appear better overall but will keep any water potential water out of the boat. I found that I have 3 places to secure on each side. I have to secure the front, mid, and aft in order for this to be perfect. I am still up in the air on how to do this.

For the front, I need to build the interior wall and I can possibly latch the front of the cabins to the wall in the cockpit.

For the mid section, this would have to be done in the engine room. I am still unsure which way to go with this because there are so many possibilities.

For the aft section, again there are many options but I am leaning toward making the seats/boarding step on the aft side of the cockpit removable with tiny earth magnets (I already have them) and use the interior space as a means to secure the structure. I could drill a hole put a thick pin though the wall which fastens to wood on the hull side or cut out a section of the wall and feed a Velcro strap though it to fasten it to the hull. I’m sure you all have ideas too.

What do you think? How would you secure the superstructure (cabins) to the hull? I would like to hear your ideas.

Pics will follow tomorrow.

-Rich.

Hi captains,

Here are a pair of old Astroflight 25's. These were used in an airplane but they still might be good for a boat. The Astro 25's are brutally strong motors. Also, I have been seeing old astro 25 Cobalt motors and sometimes they are geared. The gear assembly can be removed so that they can be run direct. Just some food for thought.

http://www.ebay.com/itm/Astro-Astroflight-25-Vintage-RC-Electric-Motors-With-Commutator-/281048275717?pt=Model_Kit_US&hash=item416fc85b05

Pull the gear drive off this and you have a nice motor. I see these pretty frequently on -ebay.

Hi captains,

Today I went to my local hobby shop to pick up some supplies when I had a conversation with the main technichian that works there. We were talking about the Dauntless & I went over a few ideas with him such as installing toggle switches to get the LIPOS to turn on/off. I was interested in doing it myself..

During the conversation we hatched a plan that I decided to have him do for me. 

So basically here is what will  be done:

Aft in the cockpit area where the light switches are will be (3) 12V 30 AMP rocker switches in a medium sized radioshack type project box.  On the side of the box will be 3 pairs of female banana plugs which the LIPOS will plug into. From here I will be able to power up the port motor/ stbd motor and one for the pwr dst panel. This will also allow me to just turn on the pwr dst panel when I want to just show off the lights.

Here is where it gets cool.. Either the LIPO wires or the charger wires will be extended so that I can balance charge the LIPOS in the boat rather than remove the superstructure and the batteries. All I have to do is leave the LIPOS in and unplug them from the switch and into the charger. The hobby shop tech is going to iron out all the details so that it is professionally done. 

Once the switch panel is installed I will modify the floor as needed to have ample access below deck.

This will work out great for me because the only time I will ever need to remove the cabins will be to work on the boat. One day when the boat is completely finished (assuming that day will ever come) the superstructure will stay in place and I will only need to remove the access panels to get inside.

This is going to be cool!

-Rich.

Captains,

My coupling insert arrived today so maybe I will be able to get the motor mounts set and epoxied into place. 

While using my little battery box test unit, roughly 5V with 3 fresh batteries, I noticed that the starboard motor was running very rough, smooth then rough.  At first I thought it was just my adjustments of the motor mount but while holding the mount steady with my hand it continued doing the same smooth running then going rough for no apparent reason.

When I examined the wiring soldered to the motor I noticed it was far from a "clean and solid" solder joint (sorry, no pics) so I've unsoldered both leads, trimmed the wire back, etc., etc..  I'm even replacing the caps.  If this doesn't solve the problem I may replace the motors with a couple of Mabuchi RS 775 BB's I have available.  They're fairly comparable and luckily have the same size shaft so I won't need to order new inserts.

Another fortunate circumstance is the port motor mount is only 'tacked' into place so if I must remove it I can do so with minimal damage.



Deep,

How are things coming with your boat?  Getting anxious to see photos of your boat ready for sea trials.


Rich,

Sorry you are having so much trouble with your sound board; makes me not want to bother with using the one I have.  I don't have any instructions to guide me any way so
it would be hit or miss all the way.

Bob

It is really easy to fry them so be sure to get instructions before you start. Even with instructions my board is very complicated.

Deep,

The motors in this boat "come from a electric drill, or cordless screwdriver. They turn 21000, at 18 volts..." as quoted from the boat builders build log (http://www.rcgroups.com/forums/showthread.php?t=344083&highlight=duma+dauntless+boat+build&page=7 Report 98), so I don't know where they came from for sure.
  Thanks for the offer on the 700 but I wouldn't want to miss match the motors and I do have the 775's and may as well use them, if necessary.

Rich,

I'll try to get the instructions befor messing around with the sound board.  Before I took it out I powered it up and noted that as soon as battery power was applied the sound of the motor came on so I don;t think it was properly installed to begin with; but I could be wrong.  It also had a horn but that wasn't hooked p to a servo over ride or anything but it did work when I depressed the slide switch.

Wow lots of action lately, cool!

Rich - Is your cabin unit(s) all one piece, or split up into sections like Dumas plans call for? I can't remember...

I have nothing to report. Wife asked me to wait for the 2012 tax return to buy new speed controls. At least I won't have to sell toys to come up with the cash-ola!

Yeah man..I'm trying to iron out the technical details so that Dauntless so can run the Long Island Sound, Tarrytown & possibly Oyster Bay before I migrate south.. Today I am going to Tarrytown on my lunch break to scout out launching points.

Tonight I am going to do the last bit of work to the bilge tank and get it installed. Also, last night I reworked the watertubes so all I have to do is take wood strips and create brackets to neatly keep the watertubes and wiring along the side walls. As of now the watertubes are pushing away from the walls and I can't put the cabins in place because they are in the way of the cockpit floor. Once these brackets are in everything will be tidy & ready for the hobby shop tech...


My cabin structure is one piece...I defied Dumas as much as I could during this build. 

In no particular order here are some pictures,

These include the exhaust cube, the making of the bilge (sump) tank, the intake duct on the hull side, watertubing and more..

Continued below..

-Rich.

Hi DF, this is my Dauntless tsunami...i'm sure you all know the drill....I blast in tons of info and go quiet for a while the next tsunami brews...

It's cool that you will get new ESC's soon enough...I can't wait to see that beauty up and running...

 Hi captains,

I just got back from Tarrytown..What an amazing experience!!! I now know how the yacht club is laid out so I stood at the spot where the boats come in and out of the marina and I couldn't help to think of Dauntless slowly passing by the place where I was standing!!!

So here's the deal...

At the water's edge to the right of the boat club  is a stretch of land with a public walking path that goes along the Hudson...Off the path there are large rocks before you get to the water. After scouting the entire area out I found  one launching spot that is doable. This spot is great because once the boat sails off there are beautiful panaramic views of the Tappanzee bridge. This is what you want if you want to sail a model Dauntless..

If I was to make arrangements to have the Dauntless launched from the docks I would lose this amazing opportunity because the large protective bulkheads from the marina side are an obstruction from the bridge. I can however sail the Dauntless from the launch site to the inlet where the boats enter. This would be a spot where the Dauntless once sailed when she was in pristine condition before she was ever sold.  I would have to launch the boat and walk about a block along the path towards the yachtclub. My Dauntless would be heading south on the Hudson. across from me.


At the inlet/outlet to the marina is a large rusted and sinking barge that is tied up to the bulkhead and very old..I think that it just might have been used as Dauntless's personal gas dock..I had read somewhere that Dauntless had 110 octane aviation fuel on a dock specifically for Dauntless..Nonetheless I plan on photographing Dauntless beside that old barge in case I can one day confirm that is what it was used for.

Also near the site is a lighthouse that can be seen in the distance. I would love to get some pics with both the lighthouse and Dauntless together.

In order for me to do this I need to check the weather forecast and the tide report. Thie tide report is very important because of the rocks. She needs to sail at high tide because the rocks that get submerged are covered in seaweed which could be trecherous to step on.

Also, this mission could either be remarkable or a complete disaster. If something goes wrong on the Hudson I could lose the boat.. But if all goes well I might end up with a great photo that could be frame worthy as well as the documented fact that the model sailed this site while the Tappanzee bridge was still there.

So I have to get the Dauntless ready for this mission...

I also need one very important  element to make this all happen...I need my sailing buddy Bill!! I will need Bill to take the helm (TX)  while i'm photographing her. This is a very important task! 

Today the temps went up to 52 degrees which is rare this time of year. The weather forcast a few days ago said that this week will be a good one..So I am going to do a little research on temps and tides and see when I could do this..

-Rich.

Hi captains,

So I found the best time to possibly sail this boat on the Hudson.

It would be Saturday morning when the tide is high at 10:05 AM. So I think sailing the  around 10AM or so would be good. It will also be sunny with a high of 58 degrees and the winds will be light at only be 4mph. Does anyone want to meet up for a mission on the Hudson?  

-Rich.

Deep,

Thanks for the offer.  I checked the motors I have and the numbers don't match .  Numbers on mine are 16 digits long and your numbers were not included in them.  They apparently aren't Johnson motors, possibly Mitsubishi.

I finished adding caps and re-soldering the leads and, thankfully, the motor runs very well now; no speeding up and slowing down, just nice steady running.  I've been able to set the motor mount on this motor now and will start "filling the gaps" and putting on layers of epoxy.

Hi Bill & capn's

The bilge pump is just about complete..All I need to do is make the covers for the stuffing tube box and drilland install the through hull fitting to bail the water. On full size vessels would you happen to know if there is a common preference for it to be installed? I'm wondering if I should put it on port or stbd. Does anyone happen to see it in pics?

I don't know of any standard for bilge pump plumbing as to location of output. Obviously it needs to be higher since it is used when the boat has the additional weight of water in the bilge.
In real life larger boats have more than one pump.  Many times I have seen them with to little capacity to be of much use except for rain water accumulation. Proper protection in the real word includes a shut off on all through hull fittings. Therefore if a hose breaks etc. the shutoff can be operated and the bilge pump can rid the boat of the water. True story; I once was demoing a 26' Chris on LI Sound and noticed the performance was slowing and headed back to port.. When I throttled back a huge amout of water rushed forward and was high enough to rise above the carpeting in the forward cabin. I knew we hadn't hit anything,  so immediately lifted the engine hatches and saw the intake hose to one engine water pump had broken. I closed the shutoff, returned to the slip on one engine and was able to pump the boat with just the bilge pumps.
Long answer but thought it might be of interest to those who may not have experianced 1:1 scale boating.

Bill

Also through the transom, looked at some pics.  Looks like it's your choice. How about through one of the exhaust ports?

 Hi Bill,

This is why I love asking these questions, the answers are usualy helpful. By you mentioning the bilge hose mishap this has just inspired me to add another pump. This one will be all the way aft where the hoses come and go through the hull. Just last night I was trying on the superstructure after spending a lot of timetaping the tubes away from the cockpit floor when two of those hoses popped off when the floor was put back on. If I had the boat on a pond or even the Hudson for that matter it could have been disasterous. I decided last night that I have to cut out the floor corners in the same area that I thought it was done on the full sized boat. This will allow the watertubes to correctly travel to the transom and in my case, let the superstructure rest on the hull. So the next time I mess with the boat will be to cut out the corner section and make & install the step/seats in each corner.

Also I am going to create a bulkhead likely adding to the one that was created for the waterpump mount and epoxy.silicone it. This would let me know if a hose broke and started filing that area. I would have to order another pump which is no big deal.

Last night I installed the sump pit and hooked it up. It operates automatically so I don't have to do anything. It runs on a 9V battery which I have mounted to the wall with 3M hanging tape with velco. In addition, the rudders were hooked back up and I ended up using black duct tape to hold all of the wires and tubes to the aft walls. I tried to epoxy wood strips in place but it became a grueling task because the tubes were trying to push away from the wood.. So after an hour of me being all glued up and the woods not sticking...I said to heck with it and ducked tape those sons of puppies to the walls...It actually looks neater because you don't see the wood or the wires..This is what happens when it's late at night and frustration kicks in..

Here are some pics..

This will give you all a general idea on how the engineroom looks. In addition you can see that the rectangle boxes have the hoses going to the sump pit. The sump pit hose inlets are in a lower area than the rectangle hose outlets so that gravity will do it's job. This is important if you do this. I still need to install the thin aluminum splash guards and tops to the rectangle boxes. Furthermore I am pointing at the bilge hose. It is too short and has to be replaced with a longer one. So today I will swing by and buy one.

Hopefully my bilge tank will further inspire you guys to keep the water gremlins out of your hull.

Also through the transom, looked at some pics.  Looks like it's your choice. How about through one of the exhaust ports?

Bob




Thanks Bob, I will try to zoom in on some full sized Dauntless pics and see if one stands out..I would put it through the exhaust port because I would have to make a custom fitting and I will never know if there is a big leak. I want to see how much water is coming from the boat. I am likely going to install it on one of the engineroom side walls. Being that I am going to have to drill into the hull I want to make the location count. I will also look at videos and pics of my boat underway so that I get an idea of the waterflow on the side of the hull. I don't want outside water coming in either.

all the little things to consider.. 

-Rich.

That is why I usually try to stay away from water cooling. with my real life experience and  I have seen videos of RC boats sinking that appeared to be hoses coming off since there was no other obvious reason. So far only the Red Baron is water cooled.

BTW did you see the fire that happened to the Boeing 767 Dreamliner at Logan was caused by a lithium battery? Boeing took a big stock market hit from it.

 Hi captains,

I found the bilge outlet on the hull. It was on the starboard side just at the bootstripe It was located next to the bulkhead either on the engineroom side or the owners cabin side. 

Then I was looking at the running characteristics of my boat in the Binney Park video and most of the water kicks up right where I would place it. I see two scenerios. One, nothing will happen because the tube will travel very high up before settling back into the pump and the water won't make it over or two it wil lkeep my bilge pump busy because of all the water will backwash back into the sump pit. It's hard to say for sure what will happen.

What do you guys think?

-Rich.
