I didnt use the navy compact in mine as it is more often than not noisy.

What I have in mine is as follows:

Two rudders as supplied

230mm propshaft with oiler tube and fine pitch 35mm 2 blade prop

I used a Deans Marine Kestrel 5 Motor. (Oh so quiet)

Overlander 50amp speed controller Discharge: 50A forward/20A reverse. Plug in and go, no set up needed.

Tornado TRC4300 9.6v Sub C Nimh battery  which I positioned crosswise about a third of the way forward  from the transom.

I get about  45 mins run time.

hello there Mick

regarding the instruction book for the PT15, what our Dicky forgot to mention is there are one or two of us who really struggled with this instruction book which THEY SAY is in English  and, to be honest with you, the Plan was more help than the instruction book.

 I am not, what you would really call, a Kit modeller - but, I was bought the kit as a present by the better half - along with all of the kitncaboodle - the motor which is actually recommended for the kit along with all the sound units and bits and pieces - to start off with the motor that is suggested is the one with the gear box and as Dicky mentions you can hear the thing run from 4 mile away!  it is so noisy.

The sound effects from Robbe - the horn sound - when I was testing it out - my wife thought I was strangling one of our pet cats.   Then there was the engine noise - a series of click, click clicks, and that my friend is a diesel engine   -  not very impressed.

As far as building the model is concerned, I quite enjoyed it to a point and I would think anyone who does do kits seriously - it will quite easily turn into a lovely model.  Hey and before our Dicky says anything - Yes........mine is sitting in the loft....its sulking....cos it just needs its guns painting & not to mention its sea trials.

aye, John e

hiya john

i was given the kit myself i usually  build my own models the water cooling bit is new to me

 dicky d said the kestal motor was water cooled on deans marine site it doesnt  mention

a cooling coil or do i have to buy one separate  i have heard the horn of the robbe foghorn and i

agree with you its terrible sounding  the speed controller he said to use looks the same as one on

ebay at half the cost?  i have not bought the motor or e s c  yet i just wanted feedback thanks lads

have you put any figures on yet as i like to think it is not finished til then just my opinion i was going to

modify some 1/35  airfix eight army multipose figures to or us multipose figures decide which are best

well thanks lads you are a great help just hope i can do it justice like you lads

Figures are on all of mine, see photo above. Modified toy soldiers from Toys-R-Us

Deans reckon their motor doesn't need cooling, but it does get hot after a while and it is easier to put the watercooling in now as appose to later.

Water cooling coil for 500/600 motors and intake and outlet and silicone tube from.

Hi Mick

I use Redbank Models a lot and find Gary very helpful and efficient.

Having said that Cornwall Model Boats are also very good.

Good luck with your build, if you need any help just shout.

We welcome well written contributions from Website members on almost any aspect of Model Boating with a particular emphasis on practical hints, tips, experience and builds.

In order to maintain a consistent standard and format, all suggestions should first be sent to me by Personal Message for approval in principle. Only a very limited amount of time is available for editing contributions into a suitable format for placing on the website so it is important that the material is well presented, lucid and free from obvious spelling errors. I think it goes without saying that contributions should be illustrated by appropriate photos. I shall be happy to give advice on this.

The Member Contribution area offers space for short informative mini articles which would not normally find a place in Model Boats magazine. It is an opportunity for Website Members to freely share their  expertise and experience but I am afraid that virtue is its own reward as there is no budget to offer more material recompense!

I look forward to receiving your suggestions.
