📝 Sub dive system.

Hi Peter,
"I am slowly being swayed towards a gas system where the water is pumped in and whilst being pumped out, the gas bottle replaces the air. This will enable a deeper dive than periscope depth. You just have to avoid running out of air."
Hmm! Must admit I also once considered experimenting with something like Sparklets bulbs.
But they are very difficult to control. How often have you sent the soda down one side of the glass only to see the whisky shoot out of the other side?😭
Also they run out! Not to mention all that CO2 release to the atmosphere - Bad Footprint😮
I concluded it was best to leave that to less critical things like experiments with torpedoes.
A 'gas tank' per se would be very heavy.
One of several reasons that I opted for the Akula with a piston / tank solution.
Cheers, Doug 😎

Hi peter,
Attached a pdf of the allowed frequencies here.
You'll notice that the UHF 433MHz frequencies mentioned somewhere amongst this sub stuff haven't been available for RC here since 2008!
Lower French frequencies? Puzzles me.
Attached is also the UK and European 40Meg chart and channel numbers.
Both bands start at 40.665 !?
Possibly some rogue channels in France.
The French ALWAYS do their own thing😉
Surprises me that you can run a 35Meg set on a 40Meg crystal!
Wouldn't have thought that the rest of the circuit would resonate properly.
(Psst! Don't tell anyone but when I first came here all I had was a 35Meg Sanwa set.
I used it for my destroyer cos I didn't 'ave nowt else, until I could afford to buy my first Graupner MC-10 'computer' set.) Quantum leap😉

"why would you risk losing sight of it."
That's the whole thrill of it Martin.
"Obviously the deeper you go the higher the pressure, the air inside the compartment will expand."
Er .. No! Due to the cooling effect of the water it will actually contract, thus reducing the internal pressure. Venting air from the dive tank to the internal tube counteracts this effect.
Trick is not to overdo it and blow the seals.
Some systems use two smaller tanks and vent to forward and aft sections separately. Too complex for me😮
I'm off to the cellar to dig out my Akula kit and read up on how that should work.

Hi Pete,
"which would react if signal was lost or can be triggered manually. "
Hmm!? How would you know WHEN to trigger it manually?
May already be too late!
"safety blow valve" what does it 'blow' and where from?
If you use the piston tank method and Fail Safe module it should automatically vent the tank on signal loss or excessive depth. S'pose the same could be applied to a bladder and pump system. Read the book carefully, I'm sure you'll find the inspiration you need in there👍
BTW: have you ever watched a submarine race!?
'bout as exciting as watching grass grow 😁😂
Funny coincidence!
There is a documentary on the haunted fishtank (GEO channel) at the moment about the Apollo programme. 50th anniversary of the first landing coming up at the weekend!
And right now they are showing the background of the 'cardboard, sticky tape and old sock' incident!! They just showed the 'prototype' and one that the crew made😀
Cheers, Doug 😎
PS "I will be running the sub in a bit of a murky river ..."
Recommend then that you fit a brushless motor with some Ooomph in case you get caught by a current! I'd be scared stiff to dive a sub in a river 😮

Hi Ian,
The Nürnberg Toy Fair is vast and is for everything from baby toys through games to sophisticated model building, robotics you name it!
There are days for the pros, manufacturers and distributors, and days for the prols like us
to go and empty their pockets and wallets. 😁 So check the programme carefully before you book your tickets! For me it's about a two hour trundle up the A9 Autobahn😊
For more pure model building you might like to look at Düsseldorf and Friedrichshafen where large model exhibitions like Intermodellbau are held. With demonstrations of all sorts of models, slow-fly hangars, field for the big stuff and hellis and drones, very large pools for boat demos. These venues are attended by all sorts of manufacturers from complete kits to all the little bits n pieces makers.
I'll try and dig up the dates and links - my new Modell Werft magazine arrived today, there is usually a listing in there of all upcoming exhibitions as well as Show Meetings of several major model Boat Clubs. Many of which attract international exhibitors and competitors. Especially the Dutch and Belgian participants who turn up with huge harbour layouts and dioramas!
More soon.
BTW the Nürnberg show has been and gorn☹️ it's in March I think.
Cheers, Doug 😎

Hi Fred,
2.4 on the surface is fine of course.
433Megs also, slightly better than 2.4G but still severely restricted under water.
"as the old 40Mhz has more or less gone for good"
Almost but not quite😊
There are still some model sub specialists who still do 40Meg stuff, and some of it tailored to 'Pig Boat' driving👍 This is the one I use most.
https://engel-modellbau.eu/shop/en/home/
As you can see on the Home page even xtal-less 40Meg RXs are no problem.
Lots of Futaba stuff still available as well.

What you see in my Avatar is only the half of it Martin😋😊
Gisela was struggling through the other half with a big grin on her face😁
Shucks, can't find the pics now, was several years ago at a Santana concert in the Olympia Halle here in Munich, 27th May 2006. 😮 Tempus fugit!!
Probably have to connect up an old external back up drive to find them.
Just ordered replacement grill/oven. Slightly bigger than the old one but not THAT BIG!!!

Hi Pete,
Definitely a different edition! See pics.
ID page only says Reprinted 2005 though, nothing about 'Revised'.
Foreword from Norman is also still the 1991 version!
Some of the tech components may have changed (shrunk?) in the meantime but the principles haven't👍 Scan or photo a page or two anyway for comparison.
Cheers, Doug😎

"Sub guys recommend 3mm as standard. Oooopss!!😀 "
Must admit that was my first thought!
I actually first wrote 3 to 5mm, then changed it to be on the safe side🤔
Didn't want you contacting a compensation lawyer😉

Dat's bedda👍
Nice one, especially viewed in 1080 HD.
Brings back memories. Funny, lake seems to have shrunk🤔
My destroyer was free running in those days, had to run round the lake to catch it!
Rudder was set by turning the depthcharge rack on the stern.
If she got stuck, or ran out off puff from the 4.5V flat battery, Mum would hold onto a reel of Grandad's light fishing line and I would walk the end round the lake (er .. pardon me Madame😁) until I could snag her. (The ship not the Madame😮)
Those were the days! Or were they?

Just specially made to slot into the particular heli as a spare part I guess.
Two mini or micro servos would probably do the same job at half the price!
Gotta go now, to buy a new mini grill/oven - the old one went bang💥 (and took out the mains circuit breaker😮) while grilling the sausages for Sunday breakfast😭
