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.
-
@benny thankyou, funly enough I am waiting in them 2 issues to come through the post from ebay!
-
@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?
-
Sorry, I thought it was just the Tx you wanted.
Try Howes Models

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
-
Talk to Howes - they will advise you of the differences.
John

Thanks John

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.
-
Yes I think I may order.one today.
The first tick off my list
-
I have decided to use an Electroniza speed controller, but how to I work out which rating I need?
-
It was the 15 amp, FR15 controller I used in my Envoy.
http://electronize.net/model_electronics_frames.htm (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.
Craig.
-
@craggle thats great mate, will get right on it
BEC sounds perfect, one less thing to think abiut
-
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
-
...and also any suggestions on what type of batteries I have to chose form
going with the 6v option
Thanks

Thankyou Inertia
-
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.
-
@Bob K yeah I agree, only as strong as weakest link and all that.
did you run the separate BEC on yours?
have you any pics?

Yes, I usually buy the Action BEC board. Just £9. Quite small. Power input from your 6 to 15V battery, regulated output 5V for your receiver / servo controls etc. Saves adding extras batteries etc. BEC = Battery Eliminator Circuit.
See http://www.action-electronics.co.uk/pdfs/P19.pdf (http://www.action-electronics.co.uk/pdfs/P19.pdf)
PS: Are you building the military or civil version. I do like their armed tug myself.
-
Yes so this provides the lower voltage reducing down from 6v.
I am going to build the military version...am excited but nervous
-
I shall be following your build with great interest. Any questions, there are many here to help.
-
Brilliant, thankyou very much
Also please have a look at my other post with my finally finished work area...

Dave, if I remember correctly AcTion have a link on their website with schematic layout of the electronics required for Slipway models, everything is matched for the particular model, even tells you which motor, battery and fuse combinations etc. Only going from memory here as it was some time ago that I built Slipways Maggie M and longer still when I built the Loyal. Give Slipway a call or drop them an email, Laurie there is really helpful so too is his better half! Slipway boats build really well and can superdetailed if you choose to do so. The Assurance is lovely looking model........good choice. May I wish you all the success with your build, take it slowly, follow the instructions to the letter and you will have a boat to be very proud of. I attempted builds from other manufacturers and failed (not necessarily their fault) but the Slipway ones were the ones I succeeded with and taught me the skills I needed never to fail again. Once again, good luck, enjoy and we will all look forward to your progress through to the wetting of the hull!
All the best from a fellow Dave
-
Dave, I've got the electronics for your Assurance build if your interested, they were intended to use in the Maggie M but as it was just a build for display the electronics never got put in (built it for someone else). They are all the AcTion items that are required for the Assurance........fits Maggie, the Loyal etc etc i.e speed controller, fuse indicator, bec board. Everything is new, never used and comes with the silicone cables (black,red,blue and yellow) plus the switch and fuses.
Yours for £50 posted if your interested.
Cheers Dave
-
Dave you are an absolute legend!
I have found the action diagrams and have been making a list to plan for purchase, everything that you have available.
I would be extremely grateful to take you up on your generous offer if you are sure?
hoe would we go about making payment?
message me if its better than on here?
Dave
