Rebuild starts - Posted: 9th Sep 2018
Well it has been a while but I can now continue with the renovation.
I have purchased most of the weaponry from Battlecraft and I must say that I am impressed with the quality. I will add pictures of these later in the build.
I have started to prime all of the wood. Removal of the final areas of the original paint was a task but I got there in the end. I have applied sanding sealer and rubbed it down with 1000 grit wet and dry. It is starting to look and feel quite smooth.
Have you built the 50cal guns yet Doug? I would like to buy some but I am concerned that they might be a little brittle for me to handle.🤔
Just a couple of questions to ask before I get on. Can I have suggestions as to who supplies good quality wooden kits to build at reasonable prices. I need to consider my next project.
I want to buy a 0.8mm air brush for the larger areas as I am finding 0.5mm too small. I have my eyes on an Iwata HP-EP. This is for sale on ebay new at £122. Are there any suggestions for a better and or cheaper solution.

Hi Pete,
The tables and dim drawings in the catalogue give both.
Response by MouldBuilder on the 21st Oct 2018
Thanks Doug. Finally made a decision and bought the Raboesch RAB301-09 shaft with ball bearings. It comes in at 450mm but can be reduced to the required 350mm of tube length.😉
Response by RNinMunich on the 21st Oct 2018
Glad to help Pete 😊
Don't forget that the tube stops at or just after the hull breakthrough.
Only the rotating shaft goes back through the A strut bearing to the prop!
That's the beauty of the Raboesch shaft assemblies, they are easy to shorten to accommodate this👍
Cheers, Doug 😎
Sanding down. - Posted: 24th Mar 2018
Started the long job of sanding down today. I think this is going to take a while. During last week I spent the time removing all of the deck parts still attached.
The motor, rc gear, rudder, batteries and prop shaft have also been removed leaving the basic hull and decking superstructures.
I have visited my local model shop today to see if I can sort out the paint. I have decided on acrylic but the cans are so small that I would need loads. I also cannot find a suitable red for the hull bottom. I am looking for matt. I was also considering making the main colour Pacific Green or similar. I have found Navy Grey which might have to do.
If anybody can help with where to source suitable paint in reasonable quantity I would be grateful.
I have purchased the sanding sealer and primer. I was considering air brushing the whole project but not so sure now. Any thoughts?😁
I have taken pictures of the progress so far. A lot of sanding still awaits me.😡
I purchased two Mk 17 gun carriages for the tubs. I cannot believe it but they fit perfectly. A picture of these is also below.
One last question for now. Should I brush paint, air brush or spray can. The boat is 40" long.
Another long day of sanding tomorrow but with greater care as I am tackling the skins. I remember how thin these were when I originally constructed the model.🤔

Thanks Jarvo and Doug. I will have a look around. I think there is a place nearby. I will ask my friends who run a garage opposite to my factory.😊
I will have to take some boat pictures with me for a colour match.
Sanding to complete today, I hope, and then preperation for sanding sealer and my newly peuchased primer filler. Lots of work ahead.
I bought another easy kit to do so I will start a second build blog soon. This one is a Police Launch with an ABS hull. The hope is that I can do both projects at the same time. Doing two things at once is not usually good for me.
I have got the urge to get a boat onto my river as soon as possible. I just bought a cheap twin hull offshore power boat to keep me going.I go to Hungary in a few weeks so will send it there to try. I will video the test as it will be the first time in years since I sailed a boat, but a first for one capable of this sort of speed.😱
I will post pictures when I finally remove all of the paint from the MTB.
I really appreciate all of the help given. It removes the trial and error which can be costly. Thanks.😊
Response by MouldBuilder on the 30th Mar 2018
I would like your opinions please.
I would like to paint the main deck and sides green and the anti fouling red. In my opinion, the best matches are RAL6020 for the green and RAL3007 for the red. It has taken me hours to come up with these but I would like second, third and fourth opinions.
I have included a sample picture I found on a Google Image search.
Response by MouldBuilder on the 13th Apr 2018
I had the colours mixed but unfortunately I could only get 2.5 litres of each. Enough for 100 boats I think. 🤓
I will start the spraying when the weather warms up a bit. That leaves me time to start on my new Police Launch project. Oh and launch and test my new twin hulled offshore power boat.😱
Renovating my Aerokits Patrol Torpedo Boat. - Posted: 18th Mar 2018
I built this Aerokits Patrol Torpedo boat over about ten years and finished, as I found painted under one of the life rafts, in 1993. I sailed it at my local pond and all went very well. The only problem I had was the speed. It was quite slow. The MFA brushed motor was strong but slow.
I have received a lot of help so far on this site for which I am grateful. I have decided to do a complete renovation which is scheduled to be completed whenever. I work all day so can only spend limited time doing this. We will see how it goes. I must admit that I am not too concerned with the result being authentic to the prototype. If it looks good and I like it, that`s good. Sorry if you like things to be perfect to the original.
If you see something I plan to do which you feel can be tackled differently, please shout. I may not always follow advice but I will always listen.
I have attached a few pictures of the boat as it is for reference. It`s still not too bad for 35 years old. Just in case you notice, I have no idea as to why I thought it was a good idea to block the Captains view with a gun tub.😱
I will be stripping the deck back to bare bones soon so will post more soon.
Thanks for looking and in advance for all the help that I am sure is just around the corner😊

Thanks Boatshed.
I have now purchased a brushless motor which I am making a mount for. I have a feeling that the lack of speed will be dramatically improved. I hope the hull will stand up to this dramatic improvement in power.😊
Response by BOATSHED on the 3rd Apr 2018
Brushless motors are fantastic, but you mat still find that prop will not be workable with a brushless. You may still need to experiment with props of different types and sizes. Unless you find someone with the same power set up and they can tell you the prop size that it works well with. I even found that rudder sizes made a difference on how the boat performed on the water. They can act as a brake and even cause the boat ti dig in on turning. Any way good luck and happy boating.
Response by boaty on the 19th Sep 2018
I had an MFA Spearfish in the mid 1990s and it was powered by an MFA Marlin or should I say underpowered. The Marlin was a good motor but was not really suitable for fast craft such as a powerboat or fast service launch like an M.T.B. I understand that MFA did an 850 which was for fast scale type models but in the end I put an Irvine 25 I.C in the Spearfish. At the time there was a motor called a Buhler which I think was Swiss . I used one😁 in my Perkassa running on nicads which performed very well.
For the Aerokits P.T boat there are a lot of suitable brushless motors around and running on lipos will certainly give you all the speed you want.😁 Boaty
