I've always wanted to make a mini/micro rc boat. So far my builds have been limited by 'standard rc equipment and suitable kits.
Accidentally I stumped over the Peba kits available on the German hobby-lobby site. I actually bought two kits: the Mooring tug I in 1:32 and the harbour tug Fiede in 1:50.

The webshop is not modern, and you have to make a money transfer using your bank account, but the staff is very friendly and relyable. By mistake I transferred 1 € to much. Hence this the package included a handwritten note concerning the extra euro and a 1 € coin. Both kits include 3D printed hulls in very good quality. The kits include 'everything' except paint, glue and rc equipment. The only disappointment was the motor supplied with the Fiede kit. The motor is a standard no-name 130 sized motor where as the motor in the mooring tug kit seems to be of good quality.]http://www.hobby-lobby-modellbau.com/onlineshop/product_info.php/info/p6325_Tug-FIEDE---1-50---Kit---38-90355.html[/url]

A main concern regarding micro models has been the needed rc gear. You can easily source micro rx units using google, but finding corresponding transmitters seems like a mystery when you are a newbie like me in this area of modelboating.
To be on the safe side I found another German website offering:
'Complete set BASIC PLUS, 2.4 GHz for 1:87 trucks'. This set has a rx/tx with esc meant to fit a small 1:87 truck. I asume it will also fit in the tug Fiede.

Thanks for sharing these kits :-)

Thx. for correcting the link, I dont know what went wrong. Hope the next one's are better. With regards to the HEIN tug it appears to be available for orders as of now. I actually ordered one myself although 3 tugs in a row has a very low WAF factor. Seems like an interesting kit that might call for a V-tail mixer.

The sterntube
The sterntube ø3mm is a tight fit in the tunnel in the printed hull.
However a tight fit is of course to be preferred for a loose fit.
The tunnel had to be expanded with a 3 mm drill.
-
As stated before the motor is a noname 130 size motor.
[/size]The rpm of this motor could be anything from 5000 to 18000 rpm. [/color]
[/size]Your guess is as good as mine.[/color]
-
In stead of using the supplied i use this one.

-
This 130 motor is rated at 6v 3000 rpm which should be suitable.
-
The kit also come with a small steering servo with a standard Futaba plug. The 'rc kit Basic Plus' that I aquired, comes with an even smaller servo, that has a plug that fits with the supplied micro rx. I expect to use the Basic Plus servo - 'Rohs'.
-
Temporary mounting of the steering cabin with railings and ladder.
-
The motor connection to the drive shaft is a very tight fit, and I removed a small part of the motor support to avoid stress in the driveline.
-
The propeller blades were soft soldered to the propeller bushing. There is a tiny umbraco 'bolt' fastening the propeller unit to the driveline shaft.
-
The rudder shaft did not have the correct angle to 'hit the hole' in the rudder support. To fix this I made the hole for the rudder bushing a little bigger and glued the bushing while the rudder shaft was is the correct position in the rudder support.
-
Paintwork in progress and the rudder alignment seems fine.
-
My "Tug HEIN" is now en-route so looking forward to starting - Trip to the Sports and Model Shop Dingwall planned for the weekend - just for the essentials ;)
Quick question - what type of paints did you use.
-
ALL 3D printed parts was sprayed with an acrylic filler/primer from Motip.

After the primer I used an acrylic spray from the same company for the blue parts. The rest was brush painted with acrylic paint from Revell and LifeColor.
Good luck with Hein, hope to see some pictures.

Looks like it’s to be a brilliantly finished model :-))
Edit:
Was going to ask about the propeller blades not being shaped but can now see in your last picture they have been made into aerofoil profiles. :-))
-
...............................Was going to ask about the propeller blades not being shaped but can now see in your last picture they have been made into aerofoil profiles. :-))
Have they? Look pretty straight to me just given pitch to throw the water as the prop turns. At this size does it make a difference if the blades are not aerofoil shaped or that the pitch increases the further you go from the hub? I suspect not.
I love it that they give you a kit to make the prop. That is really old school.
Enjoying the build. Looks great. :-)) O0 :-))

I’m in sleepy mode at the moment- it was the closest thing to say other than bent blades! :D
-
First floating with motor but no rc.
Hope to do some soldering on the rx later today.
-
Still motor but no rc.
-
The soldering of the rx went ok. Actually it's the esc that must be soldered. After connecting the battery thx tx led started blinking and was ready for binding.
-
In order to use the rx/tx rx35 and Devo 7e, the Devo must have a sw upgrade. According to the sol-expert web site this is a simple well described process. [/size]Yes...After a couple of hours on 'Google' I succeded i upgrading the sw and binding the rx/tx. After the binding nothing went well. I'm unfortunately not able to trigger any servo action from the Devo. There can be many reasons for this, but I gave up troubleshooting and plan to continue on a rainy day.Then I remembered that I have an old Tactic tx and and a corresponding micro rx. I never used the rx because the build-in esc has forward only mode, not of much use in a boat model.[/color]
-
However, the rx has two sockets for external servos. I connected an old servo, modified as esc, and standard micro servo for the rudder.[/size]Apparently this works. The setup is depicted here.[/color]
-
The connection between the motor and the propeller shaft proved to be to ridget and un-flexible.
Instead I used a short rubber tube as seen above.On the Youtube there is a small video of the first test on water. It went ok but modifications are needed.
https://youtu.be/7kEPw3oDaZU (https://youtu.be/7kEPw3oDaZU)
The wiring for the servo-esc is way to long and must be refurbished in order to save weight.[/size]The rudder must have a 'bigger movement' in order to enhance the manueverability.[/color]

Looking nice :-))
-
It's quite surprising how much equipment you can squeeze into a small hull, but try and ensure you have access in case anything needs changing out in the future :-))
Regards,
Ray.
-
Access seems to be an issue with the PEBA tugs. I have the Hein and just getting ready to paint.
I am looking at a mixture of screws and magnets to allow the deck / fender to be removed.
-
Hmmm, bit of a dilemma that one. Is the fender removable or will it require a bit of surgery? The magnets could be a possible solution...
Regards,
Ray.
-
It will take a bit of surgery to get it to work
The deck to hull is easy - I have designed some 3d printed fitting to hold the magnets & deck in place.
The fender needs a bit more thought.

WOW - it would be great to see a photo or two of those fittings you've made, when you get a chance I mean :-) .

I am trying to keep a build log on this forum - so will post them there - Unfortunately life and work keeps slowing everything up.
-
Yeah, I know exactly how that feels, by the time I'm free I'm just too tired to to do very much at all.
Still, retirement is only a few months away now, then perhaps I'll be able to do more :-)
Regards,
Ray.
-
I fully understand your concern regarding time constraints.
My retirement is 10 years ahead, but the kids have just left for 1 year of boarding school.
That should give some extra time.
With regards to hull access I decided to make the deck removeable.
The rubber fender wiĺl be glued to the hull and magnets will be used to hold the deck.
The bow fender will act as 'lock' between the hull and the deck held with 2 magnets.
Gluing the rubber fender to the lower hull. The clingfilm protects the deck from excess glue,
thus preventing gluing the hull and deck together.
-
Magnets in the bow fender.
-
Bowfender acting as 'locker'.

'Bow-magnet' above deck.

'Bow-magnet' below deck.
-
Ah, right - now I'm with you, that looks like a good solution. Good to see your progress and thanks for posting the photos :-))
Regards,
Ray.
-
Magnets finally glued in place.
-
Instead of using the modified servo as esc, I've wired the ER100 esc from the BASIC PLUS kit.
https://www.sol-expert-group.de/1-87-model-building/Micro-speed-regulator/Speed-regulator-ER100::622.html (https://www.sol-expert-group.de/1-87-model-building/Micro-speed-regulator/Speed-regulator-ER100::622.html)
The esc works very well enables very slow speed. Far better than the the modified servo.
-
In addition the to the servo i bought a new RX from tactic. I assume it's basically the same as the one I have but without build-in esc and servo's.
The steering servo is now attached to the middle hole of the rudder arm. This gives a bigger movement of the rudder given a specific servo movement.
-
Windows has now been added to the wheel house.
-
Some paint repair work needed on the bow fender :-)
cheers
Søren

There is a small video with the new esc here.

Very cute! :-)) :police:

Thx. for the kind words from Tafelspitz.
Close to the end for the work on Fiede.
Name decals and laterns added.
In the background we see the next project, a Thames slipper launch.
With regards to Fiede, does anyone have knowlegde of the original 1:1 vessel.Is there in fact a tug in Hamburg named Fiede?
Some of the Peba kits for example Tug I
http://www.hobby-lobby-modellbau.com/onlineshop/product_info.php/info/p6313_MOORING-TUG-I---1-32---Kit---38-90015.html (http://www.hobby-lobby-modellbau.com/onlineshop/product_info.php/info/p6313_MOORING-TUG-I---1-32---Kit---38-90015.html)
is actually sailing in Hamburg.
-
I'm also a bit puzzled about the given scale, 1:50 with regards to Fiede.The 'paper people' on the pictures of Hein(Peba kit) and Fiede are 36 mm high.
That equals 1.80 m in the sale 1:50, close to my own height 1.84 m.
On tug Hein, claimed to have the scale 1:50, the 'paper people' looks ok,
but on Fiede they look like Titans, suggesting that 1:50 might not be the correct scale for Fiede.
Fiede and Hein looks, at least to me, not to be in the same scale.
