Oh, I finally came across someone with identical Model such that the Hull and Windows match and it was by PUSAR and wonder where he got his?

Here is the one post link:

Yeah that one is a totally different animal. I do like those too as they remind me of the (somewhat smaller) NYPD Harbor units that used to patrol the area I used my boat back in the 90s.

The model you have with it's modified Downeast style hull is something I would really love to build/have. I like your videos and how she runs. Very nice balance from what I can see.

QuickLTD,

Thanks for your reply!

I had a choice of several models that Mr. Lombardo ask me to pick from his shelves and as soon as I saw this one, it was a keeper! Mr. Lombardo told me it is the best running boat he had in his fleet. I am so happy with my 2nd Boat Project! Enjoying it on water and off water!

By the way, I am in Tampa visiting my oldest daughter and I see you are very close! Had a Realized, I would have brought the boat so, you could have seen it in person!

Perhaps next time

Yes indeed, that is the one! It seems like what I said the first time citing Tony Lombardo about being the first "Kit" is true and now he scratch builds most of his models from a few pictures!

Thanks for finding the link for us!

That would have been nice to see. Are you mostly a plane guy? Are you going to Monster Planes in a few weeks at Lakeland Linder Airport? What kind of run times are you getting with your set up on that USCG boat?

Yes, I am RC Airplane guy, however, as you can see, I am slowing (quickly) getting into RC Boating side of the hobby.

I might go to the Monster Planes, depending on what is going on with my schedule so, at present, I am not sure.

I am "Planning" to attend the WATTFEST event South of Brandon, Florida.

That's five minutes away from me. Never even knew that field was there. I might have to check it out. Shame I don't fly.


Do you plan any other upgrades or changes to this boat?

As a matter of fact, I just got done with replacing the Rudder Servo Arm! The new one is giving me more Rudder Authority!! Thank goodness for someone who gave me free Standard size servos and the same brand such that I could use the Arms!! What a difference!

The other thing I am presently doing is trying to locate the maker of the Gearbox as I just noticed lots of uneven spin of the Spur Gear (deformed) and creating some vibrations. Presently attempting to replace the Spur Gear.

Nice Video QuickLTD! Thanks!

At 2:20 there is actual video of a restored 40'er

USCG 40-foot Utility Boat - Forties Forever (5 min 43 sec)

Guys,

You might think I am a nut, however, I filled UP my BATH Tub and placed the Coast Guard Rescue RC Model in the water and started her UP!

Used two (2) 3-Cell, Turnigy 3-Cell, 2200mAH, 25C, Li-POLY connected in Parallel and carefully measured the current Draw demand in static form.

The Results:

1/4 Throttle: 2.5 AMPs
1/2 Throttle: 4.5 AMPs
Full Throttle: 20 AMPs

3/4 Reverse: 13 AMPs

As you can see the AMP draw is no where linear and at High Throttle that Speed Propeller takes effect and makes this little boat into a speed demon.

Here is the Video!

Coast Guard Rescue RC Ship Current Measurement Brushed Geared 600 Motor 10-09-2012 (3 min 3 sec)

A few pictures of work I did tonight!

Replaced the Rudder Servo Arm and now that Rudder swings with authority!

First, I made sure both battery packs were fully charged and balanced.



Filling Up the water in Bath Tub!


Ready for the Test Run!






Post Run Picture!

Guys,

A few items that really bothered me during the Current Measurements while the model was in the Bath Tub. Ordinarily, one does not see the actual workings of the Power System while it is in water since the model is covered and moving away from you. Well, last night I had the opportunity to really watch and hear the power system and concluded the following:

1. The "No-Name" gearbox had to go since spare parts just could not be found and because the Gearbox Spur Gear was really worn and it vibrated the entire assembly at moderate speeds and including high RPMs.

2. I looked all over my hobby drawers and found a brand new Airplane Gearbox known as the Electrifly (Great Planes) GD-600 and I believe it is the 2.5:1 ratio.

3. The Rudder travel was fixed as reported earlier using a new Rudder Servo Arm and located the push rod assembly at a farther hole and that did the trick.

A few pictures of the new GD-600 Gearbox with the Stock Brushed 600 size motor.









Installed the NEW PINION Gear that came with the GD-600 Gearbox:
