71" (1.8m) TID Tug Build
« on: November 04, 2016, 10:18:55 PM »


Hiya guys / gals!


My first post here :)


Im waiting for the hull of my 71" (1.8m)TID Tug from Models By Design, about another 5 weeks as there made to order.


I feel like a child waiting for xmas, really looking forward to getting it :)


This will be the first time ive ever built from scratch (Except for the hull) The semi kit comes with the superstructure etc but im going to be making my own or at least alter the one that comes with it as I want to build the Anteo tug.


Below is a vid i found on youtube of the exact tug im getting:
http://www.youtube.com/watch?v=4OfmE7moigc


And heres a pic from the website:



But this is what i'm aiming for:



Ive been browsing around & looking up info for the build, I have plans/pics etc.. So far this is what I have in mind:

Motor
BF24 from MMM

12 pole - Hi Torque - Lo Rev - 24volt
Max revs 4000rpm
Shaft = dia. 8mm x 20mm long
Body size:-
OAL = 145mm
Dia. = 70mm

Prop Shaft
Maxline - 8mm thread http://www.mobilemarinemodels.com/maxline-2422-p.asp

Prop

PropProp-Shop, Brass 6" Diamater (about 15cm) with 7" pitch (4 blade scale prop)

ESC
Im not too sure which ESC to get at the moment, im going to go for Mtroniks Viper Marine HV, but they come in 4 different flavours: 15amp/20amp/25amp & 40amp, so i'm not sure which one i should get thats best for my motor, any ideas?

I will be using 2x 12v Gel Cell batterys, again there's different types in terms of Ah, i was thinking around 7ah, but there also 10Ah, am i right in thinking that the Ah is basically the capacity, so the higher the Ah, the better the run times?

As for the actual build, im thinking of using 1.5mm ply for the superstructure & 3.5mm ply for the deck (i will be using 1.5mm planking on top of the deck)

Then for the bulkheads & battery base i'm thinking 10mm ply?

The rudder i'm going to have to make this myself out of brass, but i'm not sure what thickness of brass i should use, so any input in this would be great, at the mo i'm thinking around 3mm? The length of the rudder isgoing to be around 15cm as thats the diamater of the prop!

Anyway as soon as the hull arrives i will post some pics & throughout the build...no doubt i will be asking many questions and asking for advice during the build from the experts :)

Cheers :)

Daz

FAO Forum Dev, whenever im trying to post im having to go back into my post (using Modify) as all the font sizes get messed up, its auto putting the [ /size] tag in random places of my post!?

I hope you have a launching ramp where you sail, at 71" she's going to weigh heavy, not something
you can lift in & out of the lake by yourself I would think. My tug is a mere 35" & she weighs 2 stone.  :-)

hiya :)


most of the weight will be in the ballast/batterys which i'm going to make removable to make transporting it doable, infact it would be almost impossible to move around (out of the water!) with the ballast!

You can usa a car batt in her.....as for a Esc i personally wouldn't waste my money on a mtronics.go for an ACTion one far more reliable and less likely to catch fire..........that reminds me i must finish mine

If memory serves me right Alan's Tid in the video used to run a 750kva brushless on a reduction gbox

Hi, you state the motor is 24v and you are using 2 x 12v batteries, are you going to wire
The batteries in series = 24v or in parallel = 12v. If it's 24v check your esc can take that voltage
As most have a max of 12v.

Hiya guys :-)


Yup i will be running the batterys parallel (24v).


Im guessing the mtroniks esc is not very good then, thanks for the heads up, i will go and checkout the action one you mention :-)

I jist had a look, that action ESC seems great, i looked at the diagram for it and it mentions the p92 distribution board, is that what id need for connecting power to things like lights/sound module and fog module etc? And should i connect to the main drive batterys or should i just use a seperate 12v gel cel for the modules so it leaves the drive batterys free purely for the motors?


Thanks :-)

Nothing wrong with Mtroniks ESCs. I've used them for years with no problems. Before deciding what amperage capability you need, you need to know what amps your motor is going to pull. If you buy an MMM motor they should be able to give you some guidance.

Ah oki doke thanks for that :-) 


Ive emailed MMM On few occasions asking for such info about motor but no replys :-(


How do the distribution boards work, im guessing it will let me power different devices with diff voltages from 1 power source (ie: 12v battery)?


Thanks

Hi,
Mtronics have two 24v brush ESC. Designed to take fully charged 24v lead acid batteries or 6s lipo's.
Mtronics ESC are modern tec, not something designed last century. With excellent customer service. I have both brushed and brushless ESC from Mtronics. Never had any problems with them.

The action Power dist boards only distribute the same voltage that is supplied from the main battery, ie 6 - 12v, except the 5v BEC circuit for the radio receiver.  Have a look at the Action wesite via the component shop to view the many wiring diagrams showing how various components are connected together.

Hi, again,
running the 2 - 12v batteries in parallel will give you 12v not 24v they will have to be wired
In series for that voltage

Hiya tid :-)

Thanks alot for info much appreciated! Did you buy your motor from a scrap yard as ive had a good look online at car breaker sites but cant seem to find just the fan motor and theres lots of different ones which only come with the fan :-( also did you have to make your own motor mount?

Any pics of your tug :-) ?

Dont suppose you have a link for the battery you use for the motor by anychance?



Info for rudder would be great!


Thanks again! :-)

Look at the component shop website ....they are under the lead acid batt section.......stick a couple of 063 sized (they fit a mini/small car)car batts in it and connect them up for 24v

Hiya Starvos :)


I just had a look but the biggest I found on there was 35Ah: http://www.componentshop.co.uk/batteries/lead-acid/?___SID=U&capacity=258&voltage=146 which weigh in at around 10kg each


Ive been looking around and found some that are 40Ah & weigh around 14-15kg each which will help alot towards ballast, so ive been thinking...


Should i use:
2x 12v 40Ah (28kg) - For Motor only
1x 12v 20Ah (7kg) - For 12v Modules etc
1x 6v 10Ah (4kg) - For 6v Modules etc


This would give me a combined weight of just under 40kg, im guessing that the total weight of ballast i need for my tug will be around 50-55kg, but will know for sure as soon i get my hull & do a ballast test.


If i did decide to get the 40Ah batterys, would my charger still be suitable: http://www.logicrc.com/?ItemId=O-FS-LX60BP&s=c:0,c:40
And maybe i should invest in another charger so i can charge 2 batterys at a time?


Cheers :)
