Coast Guard Rescue Ship

My good friend, Tony Lombardo of Titusville, Florida gave me my 2nd RC Scale Electric Boat yesterday. According to Tony it is his very first "Kit" RC Boat and I must say Tony did a great job on it.

Length of Hull: 32 1/2 inches long
Width of Hull: 9 1/2 inches wide (Widest Point)

Power System: Upgrade 600 Brushed Motor in gearbox
-- Motor Pinion Gear Count: 18 (Brass Metal)
-- Gearbox Spur Gear Count: 38 (Nylon Composite Material)
-- Therefore, the motor has to turn 2.11 revolutions for each complete rotation of the Spur Gear (Propeller).

ESC: Traxxas XL-5 Brushed ESC with Reverse
Radio: Traxxas 27Mhz 2-Channel

Tony tells me the Kit resembles a US Coast Guard Rescue Ship and I performed a Google search and found this one:


Of course I have Video of today Test run at our Moon Port Modelers RC Club and it was fantastic Sunday morning with crystal calm water.

Here is Tony Lombardo's Picture when he had it with Brushless Power!!!


Sorry for the shaky Video! I was trying to Control the model while the Video camera!

Populating an empty Hull.

Okay, Tony Lombardo gave me this fine looking RC Electric Boat Satuday, 10-06-2012 and I wasted no time and went crazy going to the local Hobby Shops before they closed on Saturday and came home and performed an All Nighter (no sleep) and was able to finish the model for operation and test runs.

Here are a few pictures during the night in getting a large 600 size Brushed motor and Traxxas 15XL ESC inside the Model.

Terminator connectors, I decided to install 4mm Bullet Connectors to match up with the Traxxas XL-5 ESC.


Since the Traxxas XL-5 Brushed ESC is Air Cool with the Large Heat Sink, I made up a Lite Plywood Decking that sits inside the Control Bridge of the model for maximum Air Flow over the Heat Sink and it worked flawlessly!!!











I got really lucky as the ESC went in without any trimming of the side windows as this was the largest opening into the Control Bridge! You had to just be patient and in it went!










As a result of placing the ESC, the location of the Receiver was easy and used a plastic bag just in case water gets splashed on the unit as it is right at the window area!!!

Initial Power System Setup

Of course, Tony did not realize that I was going to run the Boat using 3-Cell, 3700mAH, "25C Discharge" Li-POLY Batteries (Parallel) and the initial thoughts were nice and easy with Ni-MH's so, the model was retrofitted with the geared 600 brushed motor without any Coiled Cooling System.

Brushed Motor Water Coiled Cooling System

During the third run of the model at our Moon Port Modelers RC Club in Titusville, Florida and for additional Photo Shoot session, Tony gave me back the controls and I noticed the motor did not have the Punch it exhibited during gradual throttle run ups so, I brought it to shore quickly. Yeap, the motor was very HOT to the touch and you could not keep your fingers on it.

I disconnected everything and turned off the radio system and fortunately the motor did not exhibit the "Burn" Smell yet and I blew on it continuously (like if that was going to do anything....).

We went back to Tony's place and wasted no time and Tony once again exhibited the Master Builder that he is and quickly made up a new Motor Bracket such that will allow Coiled Water Cooling for the motor.

3rd Test Run with Coiled Water Cooling for Brushed Motor!

Tony Lombardo and his wife took me to a very nice Public Park in Titusville, Florida (Sand Point Park) and had park benches, picnic tables and a great view of the marina and Indian River!!

There were lots of birds and seems like cooler weather conditions are coming soon!

Here is another video showing the 3rd Test Run and testing the Coiled Water Cooling system for the Brushed motor.

In this run, I used quantity (2) of the Turnigy 3-Cell, 2200mAH, 25C, Li-POLYs in parallel and made the model much more responsive to throttle as it was lighter!

Interesting!

However, Mr. Lombardo of Titusville, Florida is a Scratch Builder. He mostly can build a model ship just from a picture taken from a Marina Dock and from plans. I do not think this is a DUMAS.

For giggles and laughs, I took a look at MACK Products and does not seem to be selling the Kit that I acquired. There is a similar one but, Hull and Windows seem very different?
