Beautiful model.
I also enjoyed the navigation even though the video was very short. ▲

You asked about video too. I've tried posting one, but I don't seem to be able to view the "media file", my own or anyone else's.

Hi Doug. Yes, the plastic screws with both the PoW and the Hood actually work rather well. The Hoods screws have very slightly off-centre holes for the shaft, but this seems to have no undesirable effects on how they work, with no vibration, and appears unnoticeable when stationary or at any working rpm.
And you are right - If it aint broke, dont fix it. I'm leaving the PoW batteries "as is (are?)". Love to see your carriers afloat sometime! Cheers from another Doug. ▲

Hi Sir Kay,
What exactly was the problem with your Hood? Re Millpond weather, I agree. We don't have much freeboard to play with do we๐ค Re Colossus class. After searching for years I was lucky enough to find two Heller kits of HMS Colossus / Arromanches as she was in French navy service. 1:400 but still large enough to do some Plastic Magic. My plan is to build one as original HMS Vengeance, and one as NAeL Minas Gerais as Vengeance was named in Brazilian Navy service when I worked on her upgrading COMMS systems in the nineties. Before she entered Brazilian service she was rebuilt in Holland with an angled flight deck, as Victorious was also rebuilt. So I have some 'kit bashing' before me!๐ฎ Forgot to ask; did you use the kit plastic screws on POW? I sometimes find that plastic kit screws work, sometimes that they are a bit blunt and flat and need some reshaping.๐ค Cheers, Doug ๐ PS Why change the batteries in POW if she works OK with the Energizers? ▲

I wondered if it was something like that with the Energizer cells, but why the PoW is okay, but the Hood is not (identical speed controllers and motors) still puzzles me. I made the mistake of rather more permanently fixing the ballast in the PoW so changing batteries will be a chore !
The foredeck of the PoW is cemented in place. The aft deck is held down by a tab at the stern sliding under the last 2cm or so of the deck cemented in place, and the main segment has a flange forward under the foredeck and gravity only at its aft end. No sealants, just the impeccable Tamiya fit otherwise as waterproofing. (small rare earth magnets in the Hood). Not a drop inside in several years but it really is a millpond weather model (with the drag of a breeze affecting the model as the square root of the scale, so a 2kt wind affects the model as a 37 kt wind would have originally, or so I am told) Tank steering! At anything more than slow ahead, the kits scale rudder actually becomes quite effective (in the prop wash, I guess), with the tank steering for docking manoeuvres only! Colossus ? Scratch build ?? ▲

Hi Sur Kay,
Many thanks for the 'innards' pic ๐ Looks like the whole deck is removable? How do you fix it on and prevent water ingress? "for reasons beyond my high school level physics I have to use a 7.2v NiMH pack in my otherwise identically motorised 1:350 Trumpeter Hood" Allow me to elucidate๐ Although your Energizer Lithium batteries (actually lithium iron disulphide) batteries are called nominal 1.5V their open circuit voltage new is normally around 1.8V. When their on load voltage drops below 1.7V they are practically exhausted. 1.7x4= 6.8. Thus your cells are mostly operating at a tad over 7V. Hence the need for a 7.2V NiMh (6x1.2V) battery as substitute. If you want to use rechargeable cells then you'd be better off with two Lithium Ion cells, nominal voltage 3.6 to 3.7. But with only about 1/4 to 1/3 of the Energizer cells capacity๐ค I too have a Spektrum DX6 system, but I won't modify it that way cos I hate tank steering! I like to have steering and throttle on one stick (the right hand one) so I can drive using just one thumb. Leaving the other hand free to twiddle other controls, scratch my nose, wave away flying bugs, or pick up the Bierkrug. (I sail on a lake with an adjacent Biergarten here in Munich๐๐) So I will use a rudder mixer to provide 'power steering'. Seems like we have similar kit stashes๐ The Trumpeter Hood is also lurking in my cellar, along with her nemesis Bismarck, Ark Royal and HMS Colossus. A carrier class which I worked on in Brazil in the nineties, ex HMS Vengeance. Looking forward to seeing your Hood. Cheers, Doug ๐ ▲

Thanks for the kind comments. Four motors with the two each side wired in parallel to a port/starboard Mtronics microviper ESC. I use 4 AA lithium cells in the PoW with no problem, but for reasons beyond my high school level physics I have to use a 7.2v NiMH pack in my otherwise identically motorised 1:350 Trumpeter Hood to avoid "problems". (not finished yet, but coming soon).
I have a Spectrum DX6E radio that I've "modified" so both sticks are on fore and aft ratched throttles. The electronically setable "throw" nicely limits the throttle ranges to scale-looking max speeds. Old photo of the guts - now a Spectrum 2.4 GHz reciever. ▲

Good job Sir Kay๐ Would love to see a short video of her in motion๐
"plastic fantastic" - AKA Plastic Magic! Any chance of some pics of your installation please? I'm highly curious as I have both the Tamiya PoW and KGV scheduled for the same treatment. I have collected a box of similar micro motors, 3V X-Drive from SolExpert, tiny Graupner Pico ESCs and some mTroniks as well. KGV came from Colin H, our dragon saviour๐, he had started building the main turrets and some superstructure, and then traded it to me, plus a collection of small motors, in exchange for restoring his Taycol Supermarine motor and converting it to run forwards and backwards on a standard brushless ESC. To do that I built him a converter board to go between the ESC and the motor. All the best, Doug ๐ ▲

That is a great looking boat. The first photo makes the boat look alive and ready for action.
