TID 164 Build
« on: September 05, 2011, 06:01:59 »
I bought a secondhand TID - 1:20 scale, Kingston Mouldings - for 180 at last weeks Convention at Haydock, what a bargain! A total runner apart from a flat 12V lead acid battery! I have dumped the old 27 MHZ system fo a newer 2.4 GHz but left the old electro-mechanical speed control to see how it behaves.....that will get changed eventually I suppose, along with the motor.

I intend to re-build as TID 164 which is preserved at Chatham.....will keep you posted!

bought a new 12V battery and took her for first sail to the Club last Sunday. Sailed very well at first but got much worse later. When I took her out to put in the car found the reason. The prop was something I had never seen before.....a 70 mm 4 bladed VARIABLE pitch! Two of the blades had become broken which explained the worsening sail.

Decided to replace all the running gear. It had a 6:1 geared torpedo 500 motor which ran very hot. Decided to replace with a MFA 950D Single Ratio Metal Gearbox 6:1 motor and a new Marx waterproof prop shaft. Do you think the new motor is adequate?

You have probably seen them but lots of detail pics of TID 164 which I uploaded on page 2 of the steam tugs section.

Thats a realy nice bargain.
Shame about your variable pitch.
I wish you good luck with it.
About the torpedo 500 I think he is too small.
That's why they get too hot.
With a gearbox he can do the job better

Nice looking tug, Alan. Best of luck with it.

You may want to check your thrust surface if she is running really hot. Had a similar problem many years ago.

Cheers mate. ;D Being a total newbie to model boats, came from model railroads, could you explain in  a little more depth about "thrust surface etc" :o

TIA ;)

If you have an engine without gearbox.
Then you make sure that your prop is not bigger in diameter than your engine.
Otherwise you're using too much power.
And you can burn your engine or your controller.
You can put your boat in the water.
And then with a multimeter to check your amps consumption.
Is your ampere consumption to high.
Then you must change your setup.
For example, use a smaller prop or use a engine with a gearbox.

As I said above I plan to use a MFA 950D motor fitted with a Single Ratio Metal Gearbox 6:1 driving a 70mm prop http://www.cornwallmodelboats.co.uk/acatalog/mfa_950d61.html. Do you think this will be suitable? ;D

Some folks allow the leading surface of the prop hub to push against the shaft tube bushing which transfers the ptop thrust to the hull. I usually place a couple of washers here. Oddly enough water is a fairly good lubricant if you can get enough of it. Other set-ups have the shaft transfering the thrust to the bearings in the motor. Either way you should check the drag and the amp usage suggested by Zeevart1 is a great place to start.

I think you mean a different engine.
When you look at the picture you see 810:1 and that's too slow.
I always use a ratio of 3:1.
Another tip from ModelTugMan.
You should check also your lubrication of the shaft.
If you decoupling your engine from your shaft.
You can also feel with your hand, or he turns to heavy or not.

   All their pictures show the same, they use a standard picture, the gearbox is a 6:1 ratio.

The propshaft has a nice ball-race just 'north' of the prop that transfers the thrust to the main shaft. I have used this before and it performs great... http://www.cornwallmodelboats.co.uk/acatalog/marx_8110.html

Oke Scribe.
than the problems are between size engine,prop and gearbox.
Just look for the right Setup.
