Huge liner model from 1929

Hi Haig, Greetings from 'Up Over' 😉
Basically I agree, Hedgehog had more projectiles but two snags-
1 The projectiles were much smaller, at 1/72 you'd hardly notice them, the splashes would be tiny. I'll have to settle for the four 'dustbin' throwers.
2 HMS Hotspur was never fitted with Hedgehog 🤔
Anyway you'd probably come along with U-181 and sink me!😲
All the best, Doug 😎

Hi Doug, it may be more impressive if you used the 'Hedgehog' as that had a much bigger spread (more splashes). For your purpose the projectiles need to be heavier than balsa but able to float (but only just).

Thanks Commodore,👍
I'm going to use a 2V SLA battery, as normal for firing up the Glo motors.
I was wondering about ignition time needed and burn out of the plug coil. Just have to experiment I suppose, trick will be to limit the amount of oxygen getting to the coil I guess.
Was planning to mass produce the Depthcharges from balsa dowel.
Maybe I could 'scoop 'em up' with my tug or fishing cutter😁

I am using the short thread glow plug. it turns out that glow plugs have a very fine thread. I think it is 1/4" x 40, National Extra Fine. Barrel is just K&S brass stacked and soldered up a few layers thick. I light it with two NimH for 2.4V and a micro switch stuck on a servo. You need to let it off quickly or it will burn up the glow plug. One battery seemed a little weak. I know it will work well for depth charge throwers. Depth charges themselves will just be lost.

It takes a bit of time to reload.

I never tried it, but someone suggested using premade ammo made from paper soda straws. it might work.

You have to be careful with this!

The sure way to succeed is, just try one more time

Hi Commodore-H,
Only just stumbled across this again and realised we were on the same track with Glow Plug ignition👍 I have a box of plugs left over from my Cox Glow Motor days and was thinking of using them for black powder ignition of the guns and depth-charge throwers on my destroyer. Thanks for confirmation of the concept.
Still trying to get my brain round the auto-reload facility though🤔

Hi WW, I don't have problems watching the stream either, just the downloaded version 🤔

Hi Commodore, black powder may be freely available in the US (as are automatic weapons🤔) but Europeans are more conservative with such things, especially in the light of recent attacks!
For instance, in Germany (I'm in Munich) fireworks are only sold for a few days just before New Years Eve.
Any tips on the construction of your barrels would be most welcome👍

I have never had any problems watching the liner clip. Thanks guys for the pyrotechnic information - I have had similar thoughts and experiment with increased confidence! Back to the plot though - anybody know any more about either the liner or Renown?

I have a firing gun on my asheville class gunboat. I live in the u.s. and i use the powder for the flash pan of blackpowder gun. it is readily available.
You need very little and it makes a nice bang with flash and smoke. I wad it with a tiny piece of paper towel and ignite it with a glowplug. The barrel is spring mounted so it recolls back when fired to complete the effect. You need to careful when building and operating this type of thing.

Hi WW! There's a lot of fascinating stuff on that site, 👍 Search 'models' and you get a lot of interesting mini aircraft, cars, tanks, complete towns (e.g. Bristol!), ships, and some pretty ladies modelling this and that! 😉
Could get addictive!

I'd very much like to know what they used for for the 'bangs'!?
I recently bought some magicians Flash Paper for the guns on my 1:72 destroyer, and 1:128 Graf Spee and HMS Belfast, which I intend to fire using redundant glow-plugs from my helicopter days in the distant past.
Wish me luck! Cheers Doug 😎
BTW I managed to download the Renown clip and the Liner, but the Liner clip jumps and staggers with lots of artefacts so couldn't see enough detail to start identifying 🤔 The Renown clip works OK 😉

Thanks for the heads-up on that clip. The Renown may not be quite as large but really impressive, again especially for the day. Anyone know anything about this model?

Here's another nice one, HMS Renown 1:120 and a destroyer, both with firing guns!! Also from the twenties. Astounding 👍 😎

Hi Charlie, I suspect you're right! A 40 footer would have plenty of room and displacement capacity for a crew. I too would like to know more, an interesting research project 😉
Possibly a film prop? James Cameron did something similar with a 50 footer I think for 'Titanic'.
Also, here in Munich I have visited the Bavaria Film Studios and seen (and been inside!) the various scale 'models' of the type VII U Boat they built for 'Das Boot'.

Hi Doug,
looking at the clip closely, I am not at all sure that any r/c was involved with the French model. I suspect it may have been 'manned'. Whatever the case, it was a major project and a very good model for its day. What I would really like to know is who built it or paid for it and what happened to it? Did it survive the war? Charlie

RC boats go further back than the twenties!!
Nicola Tesla was at it in 1898 ! 😉
"In 1898, Tesla demonstrated a radio-controlled boat (U.S. Patent 613,809 —Method of an Apparatus for Controlling Mechanism of Moving Vehicle or Vehicles)."

Interesting set of links at the bottom of this article. 👍

I often visit the British Pathe site, which has an archive of over 60,000 film clips covering an infinite range of subjects, going back to the beginning of the 20th century. I have wasted many hours looking at it. However, if you visit the site and punch in Miniature Mariners, (www.britishpathe.com/video/miniaturemariners/query/miniature+mariners), you will find an interesting selection from 1929, that includes the still extant Victoria Park Club running a hydroplane with a huge audience. The clips finish with a truly awesome liner model of about 40 feet length and apparently sea-going. The information board ( it was a silent film in 1929) tells us very little: it is French and 40 foot long. I know that it is a long time ago and French but do any other sailors know more about this?
