RTR Tug upgrade

Here is an upgrade on an RTR Tug, was called Savannah, bought from RCModels.com.
There were things that failed ( see "has anyone bought from RCModels ) thread.

The entire superstructure was re-created, only the base was retained.
Drive line fell apart, bought new from MACK models, SUPER smooth, no vibration, no leak.
7.2V motor with one BIG SLA battery for ballast, 2 lbs. copper coated lead shot in ziplocks for ballast.
Working searchlight from MACK added, working sideboard lights on the way.
Area under hawse drying rack ( rudder access ) was WIDE OPEN, I sealed it and built a new grating.
Added bitt, vent pipes, railing ( thanks Harbor ! ), new funnel, scratch water tank, tires.
Runs well, super quite, it was a platform for me to use to learn how to RC a model, it has served it's purpose well.
Now on to building my own boat 100% ....

Here is the link to to the original build thread:

Sounds like your original purchase was not a RTR, but a ready-to-fall-apart, Tim---.

Nice job on the redo.

Thanks Kap ...
Yes, the driveline was doomed ... hand made from scrap !
Looks more like a Tug and less like a birdhouse now.

Very nicely done remodel. Only one more thing for the tug...... it needs a bigger prop.

Thanks my friends...
Interesting observation green boat ...
You must mean easthetically ( I was able to blow the doors off that goose ) ...
I simply ordered a stuffing box from MACK and got the prop that matched up ...
I think the 1.48" is what fell into place.
I wonder if I can get a bigger prop. and have it fit correctly on that 1/8 shaft...

Yes, I meant aesthetically. Steam tugs had larger props because of the slower RPM's they turned.

If you cant find it Build it!
Nice Tim real nice!
What did you do the rivets out of?

And how the heck did you get that checkerd grating so perfectly straight?

Cormorant Tug

greenboat: had I been more carefull, I would have used a gearmotor with a 2" 4 blade paddle.
Longbike:The grating is from Nature Coast ( fittings in the catalogue ) 50X50mm, 6 bucks.
The rivets are just 5 minute epoxy, a nail and patience ( I like rivtes ! )
Millertime: Thanks !
woodybob: got the grating from Nature Coast ( see above ), but YOUR link has WAY better selection, I am contacting them TODAY !
