3D Printed RAF Crash Tender 35"

Plivez Openingspost 5 maanden geleden 182

Hello everyone,
I thought I would introduce myself and share my project.
I am currently building a 3D printed RAF Crash Tender.
I have used an original model obtained on Facebook marketplace as a reference along with original model plans and studying the great work on here by https://model-boats.com/user/EdH and https://model-boats.com/user/robbob
With those I have drawn up the plans on Fusion 360 and exported to BambuLabs for my printer which is the H2S
The model is approximately 35 inches long and will be powered by a brushless motor on a single shaft. I am currently working through the construction, finishing and painting stages, and will post updates as the build progresses.
I am looking forward to sharing the build with you all and would welcome any advice, comments or information from members who have built RAF Crash Tenders or similar fast launches.

Many thanks,

Thanks for the info.
I'm sure that I could get acceptable performance with a single shaft. It went fast with the 3.5cc glow plug engine.
I have 2 destroyers, one has both motors controled by up down on the left stick and the balance of power between the motor controled by side to side of the left stick. Side to side of the right stick controls the rudders. This model was featured in "Model Boats"" mag Feb 2015. I run that one on one of my 6 channel or on my 4 channel Futabas.
In mode 1 the other has up down left stick controling the port motor and the up down right stick controling the starboard motor.
In mode 2 up down left stick controls both motors. Mode selection is with one of the spare channels. I run that one on my Flysky 10 channel.
I'm planing on something similar to one of these in the crash tender. Probably one of the Futabas.

I'm presently in Canada on holiday. I'll post some pictures when I get home.

@VictorC I've used this superglue. Also have carbon fibre dowels and stainless nuts and bolts (overkill) between bulkheads. From purely a performance perspective I think a single brushless is sufficient...?

Few more CAD detail images.

I love the process, the software is amazing. Although it does feel a bit like cheating compared with the traditional methods.

I scratch build as I love working with timber but I wouldn't hesitate to use 3D printed parts for detailing etc.

Cheating you say 😮🤔.
Maybe they said that when moving from steam to IC, then from IC to leccy....Could also say building from a kit rather than scratch is same. Progress is what keeps the hobby alive, most youngsters these days wouldn't spare the time to build a wooden ship, but give them a kit and they may be tempted. I love watching how someone builds their craft from scratch, the skills and out of the box thinking involved. I don't have those skills so kit building keeps me in this great community.
I'll be interested to watch your progress and many many builders on here use 3d printing any to some extent, from some ammo boxes to full 3d printed crews. You're just moving to another level. Good luck on the build! 👌

Hot off the printer.

Hull now printed in three sections. Printed in PETG filament on my Bambulabs H2S
Quality of print is superb. Now for priming and sanding.......

Filling, sanding and painting then repainting...

Bondo and primed ready for paint.
Then stupidly got carried away and completely painted the wrong waterline. Not sure what I was thinking. Anyway soon rectified..

Waterline

The most difficult part of the process thus far. Getting the waterline tape to nicely pass over the hard chine. Happy with it eventually. Once clear coated I will paint some extra clear epoxy over the vulnerable edges (bow, chine, stern). Printed the wheelhouse cabin and cabin top. Sanding to get perfectly smooth finish.

Motor Mounted

Motor mount designed in three parts. Hull shaped base to provide a flat surface into which to screw changeable mount. Then sides and main mount face. All seems to line up very well and run smooth.

Decals

All cut from vinyl using the my same 3D printer, such a versatile machine. Starting to look the part!

A detail that seems to be missing from all the builds I've seen?

I noticed this small detail in the B&W photo of the Crash Tender. Unfortunately I've already printed and started painting the wheelhouse so probably wont be adding it.
