G'Day to all forum members from down under.

I have a fleetscale HMS T22, B3 @1:72 scale, hull and running set. Can members please advise what size motors would be ideal for this model? Also Voltage 6v or 12v...

As above I also have a Fleetscale HMS Vanguard at 1:128 scale, 4 props - advise/suggestions needed as to which motors....


Thanks in advance

PSSHIPS fits Model Motors Direct 777's but I prefer the Deans motors.

Dear Mr. Martin13,

When you find a good motor setup, finish and maiden the model, I would beg you to post it on htttp://rcgearing.com/boats.html

I look forward to hearing what motor ends up powering your model.

All the best,

Jeff

[Shipmate60]

I have also had a couple of these and Deccaperms power the Scale Running Gear well, so any motor that will give you about 3000 rpm.
Geared or direct drive?

Jeff, We will see what happens - trying to get an idea for now of which motors. I have a few models to be built and don't wish to spend excessive $$ on trying various motors T22 requires 2 motors and Vanguard 4. Will keep you posted.

Hi Bob,
For a minute there I thought that nobody wanted to speak to me (just like my wife - being ignored as usual Your friend with the Vanguard used speed 500's at 12 v  but suggests that they are too powerful.

I have heard of Decaperms sort of, but have no idea or info of them - can you enlighten me

Martin the not so motor wise

Hi Martin,
here`s a couple of links for you    (just take a deep breath before looking at the price )
www.cornwallmodelboats.co.uk/acatalog/decaperm_12v.html

you will get them cheaper in Europe so here`s a good link,I`ve used them before and was really pleased with the service

www.hobbydirekt.de/product_info.php?language=en&products_id=33796

and heres some data on Marx motors

www.eaelec.com/ea_hobby/tips3.htm

Al the best

We used Deccaperms because they are a noisy (electrically and sonically) and sound like a Gas Turbine, but they are expensive.
What running gear are you using?

550 motors on 3:1 reduction gearboxes are as good and you get the choice of 6 or 12 volts with the speed difference - faster on 12 volts.
A lot depends on your running gear.

Thanks Big Bri but those Decaperms are expensive, great motors but at that price - I think I will give them a miss.

Bob,
T22, B3 (2070mm long) Fleetscale running gear - 5 blade props, 50mm - 2 in total..
Vanguard (1930mm long) - Fleetscale/Sitek running gear - 5 blade props, 35mm - 4 in total..

Need to find a cheaper motor

Martin doon under

[Shipmate60]

Martin13,
Fleetscale recommend Graupner Speed 500's.
My personal choive for the Type 22 would be a 3:1 geared 550 on 6 volts.
Model Slipway do these.
OR
NoMustangMark on here sells some 550 motors which on 12 volts give 3000 rpm for direct drive. But they might struggle a bit on 2 inch props.

Bob

[Martin13]

Bob,

Thanks for the info.

Will go along with your suggestion for the T22 (much cheaper) and use Speed 500's for HMS Vanguard. I like the Decaperms but cost more than I wish to part with at the moment.

Only need motors for now to setup shafts and will invest in electronics at a much later stage

Thanks again Bob and Big Bri for your recommendations...

Just one thing to be very careful of is to get 550's if you get the Jonson motors they pull horrendous currents bur run about 19000 rpm on 12 volts.

Bob

[Shipmate60]

Graupner 500E motors would do with a gearbox

Specification

Nominal voltage 12 V
Operating voltage range 6 ... 12 V
No-load rpm 12000 min–1
No-load current drain 0,4 A
Current drain at max. efficiency 2 A
Current drain when stalled 10 A
Max. efficiency without gearbox 67 %
Length of case, excl. shaft 50 mm
Diameter 35,8 mm
Free shaft length 8,5 mm
Shaft diameter 3,17 mm
Weight 158 g

On 12 volts you could use a 2 or 3:1 Gearbox depending how fast you want her to go.

They stall at 10 Amps so you can use a slaller capacity ESC too.

Also I see Fleetscale are recommending different motors now.
Here is the link to theit motors page.

I have heard of those Buhler motors down here in Oz. Apparently the TF72 lads use them in various models and swear by them.

Have you heard of or familiar with Sagem motors? Also available in Oz.

Are you able to purchase the Graupner 500E motors with gearboxes fitted. Apparently Ken has installed these motors as direct drive and says that the model is in excess of scale speed - he is going to experiment with a 6v battery and see what happens.

So cant you get hold of any of those that they use?

I can Bob, it's just that I'm not sure about motors that I have never heard or know little about..It's all so confusing

Martin

[Martin13]

Also, when I'm not sure about something - I tend to go with recommendations. The lads on the forum know a lot more about motors than I do and I know that a number have built in 1:72 scale

Take a look at this.. http://www.vac-u-boat.com/KitsParts.htm i ordered from them before - quick shipping and good stuff.

[Shipmate60]

Martin13,
What is your preferred voltage?

Bob

[cbr900]

Martin,

Save yourself some freight expenses, and give John Darke
a ring he will solve your problems with motors, his range
is extensive, phone 0419142192......

Roy

[Martin13]

Weeds,
Thanks for the info - interesting site.

Roy,
I will John a ring and see what he can do - have purchased motors from John in the past. Probably best to buy locally and save some $$$.

Bob,
My tendencies are towards a 12v system as more options are available. But here is an interesting one for you.

When I received the Vanguard running set I pulled only one shaft out of the packet to check it out. With discussions with a TF72 member, decided to take a photo of running set to show him what I have as he believed that Vanguard should have 3 blade props.

Surprise, Surprise - The Vanguard set consisted of 2 x 3 blade props and 2 x 5 blade props.
Did someone make a mistake when packaging the set at Fleetscale/Sitek

Martin du

[Shipmate60]

No mate that combination of props is correct.
I will see if I can remember which way round they go.

Bob,

You are correct again. Have just received a reply from TF72 and Fleetscale
Quote:
Vanguard had 5 blade inner props fitted to her later on as she suffered severe vibration/interaction between the props. So much so that she ran her outer props at a faster speed than her inners!

 



You learn something new every day

Martin the wiser

[Martin13]

Thanks to everybody for your recommendations. I was considering the Graupner 500E motors till I was contacted by Task force 72.

As a new member to TF72, the lads can supply Sagem motors 12v for the T22 and Ford Buhlers 12v for the Vanguard at a very cheap price. These motors have been fitted to many club models with great success and reliability. Also being able to get them here in Oz also saves a heap on postage costs.

Thanks again for your thoughts and input on the matter - much appreciated

Well done Martin.
It is usually the best approach to use a well tried and tested route for scale models unless you want to experiment with different power plants.
