Model Slipway Asssurance build planning....help!
« on: August 01, 2017, 11:20:14 am »

Hi all  :-))

Well its been a long while since I was last on here, life getting in the way for one reason or another.

I am back now though and planning my build which will be for when the nights start drawing in.

I intend to build Model Slipways Assurance, in its WW2 guise.

I will be purchasing the kit plus the additional motor and coupling they can provide.
I do however need help for everything else.

This being my first serious build, it is extremely important that I enjoy it and learn from it, and to that end I would like to make sure the items I purchase for it, are the correct and proven suitable for the kit.  If I start assuming or hoping things work, my enjoyment will turn to fear and worry and the project wont end up finished.

This is where I am hoping you guys can help.

As stated earlier, I will have the kit plus the motor/coupling from Model Slipway but I then need EVERYTHING else.
So….Speed controller, prop shaft, prop, battery (do I use 6v or 12v), any connectors and additional cables etc.

Can anyone help me out with this.

Obviously it would be great to hear from people who have built this kit as to what they used and how it fared etc, but also, just general help with this project would be great

Yours in hope
Dave

Hi Dave,


I've not build the Assurance but have built other MS kits.  Looking at the MS website, it looks like you get a prop and prop shaft with the kit? In the motors section of the MS website, it give a battery voltage recommendation depending on which of the recommended motors you decide on. 


I tend to use Deans connectors between the motor and ESC and Tamiya from battery to ESC.  Some people don't like either so it's really horses for courses but I'd avoid screw block connectors.


ESC wise, I and other people at my club have had several MTroniks controllers fail so I now stay clear.  Electronize had a good reputation but I've not used them personally.  Wiring, any decent motor wiring will do, I get mine from my local hobby shop. 


Hope that's some help.

I built the Envoy tug from Model Slipway which is a very similar boat (same hull) as the Assurance.

I used their recommended motor which I think is a fairly normal 540/550 type with a gearbox which I think is 6:1 ratio. Prop shaft and propeller was supplied although I changed the prop to a brass one as the kit one was a white metal version and looked a bit soft and out of balance.

I used two 6v batteries and managed to wire them through a double pole, double throw switch so I get the choice of running the batteries in series giving 6v to the motor or in parallel so I get 12v to the motor. To be honest the 12v running is too fast and looks a bit silly so I tend to stick to the 6v power and get a longer running time.

I used an Electronize speed controller which works fine, Can't remember what power one I went for now though. Radio gear can be fairly basic and 2 channels is all that is needed to go forwards, backwards, left and right.

Thanks guys you have both been a great help :-))

@pipster yes sorry my mistake, i will get a prop and shaft with the kit, but as you say, maybe not need to review its quality.

@craggie yes I agree, i was hoping 6v would be more in keeping for the scale, and also last longer so I think that I will head in that direction. 

It also cant be coincidence that you both recommended Electronize speed controllers, so that's what I will use, just not sure of how to size it?

I have a Planet T5 controller still in box so was intending on using that and getting a receiver to match.  Do you think that will be up to the job?

Any further advice, suggestions or recommendations would be gratefully received

Hi Dave
I built the Model Slipway Envoy and this was a first for me. I got a lot of information from a kit review of the Assurance class tug by a Mr Ivor Warner it was in the Model Boats magazine August / September 2010.
Hope this helps.

Although the Planet T5 & T7 transmitters and receivers are no longer made, Cornwall Model Boats have one in stock.  . .

You may need to be quick to snap it up.

@bob k thankyou. I knew they didn't make them anymore but didn't realise there could be a shortage.
the link you sent was for the transmitter but I actually only need the receiver, which it appears they done sell.
any suggestions where else?

I'm not a Planet man but you could try Howes Models. In the latest Model boats, arrived yesterday, they say Planet 6CH receivers till available.  Planet R7M is £19.99.  I have always found them very good for other things.  www.howesmodels.co.uk

@Bob K & Buccaneer

Thanks guys

I have had a look and both R6m and R7m are available, but the R6m is £29.99 where as the newer R7m is only £19.99

I would've thought the newer one would be the more expensive one?

Am I safe to purchase the R7m to use with my T5 transmitter or should I get a R6m and pay the extra?

Thanks

Down to availability, stock and demand.  Either would suit your Planet T5.
The RM7 has more channels (7) to suit the Planet T7, but otherwise identical.

I understand that Howes bought a lot up as Planet stopped manufacture.

Ah ok

So just cos it has 7 channels doesn't mean you have to use them!!!

I feel an R7m might be coming my way soon :}

Dave.  You can only use the extra channels if you have the T7 transmitter.  No worries.  Go for it.
Five channels is more than enough for a single shaft tug, even if you want to add extra functions to it later.

It was the 15 amp, FR15 controller I used in my Envoy.

http://electronize.net/model_electronics_frames.htm

They used to sell them in kit form to build yourself. It was great fun soldering all the components on the board but they don't seem to offer that as an option any more?

It has a BEC (battery eliminator circuit) in it too so you don't need a separate power supply for the radio receiver. The power lead comes with a fuse in the supply to protect it. Some people put fuses between the speed controller and the motor as well, I'm not convinced that is needed myself.

Right

A little more advice needed %)

I have Planet T5 Tx, and have just ordered a Planet R7m Rx.

I will be using 6v battery and the 2.3:1 geared motor that is provided in the kit.

I had almost 100% decided on using an Electonize speed controller with built in BEC for this build, but it has also been suggested I take a look at Action Electronics equipment.

They do the P80 ESC speed controller, but it doesn't come with a BEC.
They do the P19 BEC separately, but which also requires a separate switch.
They also do the P95/1 indicator Fuseboard which I like the look of

I am torn between paying the extra (a good amount more) and get the Action Electronics parts, but also can’t really justify the additional cost.

What are peoples opinion experience of these two options?

Thanks all

Dave.   I would well recommend the Action gear.  It is a bit more, but well worth it for the control and reliability.
I now have Action units in all my boats.  If you are spending that amount of time and money on building an Assurance, a small extra on the controls and wiring adds to the quality and sailability.
