Stevenage MBC IC boats
Busy Sunday with 6 members bringing IC boats to the lake. Onshore & offshore footage of the thrills and spills using GoPro cameras on the boats.

40" Seaplane Tender, first test run
Finally, had a decent day (if you can call calm but fully overcast decent) and managed a try-out of the ST. Unfortunately had the pleasure of some yappy kid asking a thousand stupid questions, then his grandfather started, while I was trying to set it up. Got so distracted I ended up breaking the mast while trying to grab the boat and answer rapid fire questions. Trying to do a video and the kid's yelling behind me, and the grandfather just let him carry on.??😠 Don't mind kids being interested at all, but some are just a pain in the 'transom'
Anyhow, enough grumpy old man stuff, -boat went pretty much perfectly and is plenty fast enough, and also very economical on the batteries, (Vid was twice as long before editing) and when I stopped they were still at 3.9v/ cell (they are only 2200MAh 2s ) and were only 4.1 at the start. All in all, distractions and a bit of mast damage aside, I'm quite happy with it, (did hit the jetty at a 20deg angle at 2/3 throttle while taking photos, - going for that last shot -😀 bounced off without a mark, - lucky the jetty piles are slimy and I build tanks !)

    'I can only reciprocate "in spades'!
    Ich verstehe den Satz nicht Doug.😐

    I get easily confused in my old age Doug😐 I've got 2 cars, an auto and a manual, - I've noticed lately, when I shift to P for pass there are funny noises, (noticed the same when shifting to R for race) and in the manual, why does it make funny noises when I pull the stick back to drive off?😮
    Confused😐

ELECTRIC EXHAUST SMOKE AND WATER VERSION 2
Changed the piping around and modified the outer tube so the smoke tube now comes straight in the back, and goes almost to the end of the outer tube. The water now comes into the outer tube and flows round the smoke tube and out, stopping any suck back to the smoke pump.

    Hi Peter, had one of those Eureka! moments, and it was so simple I hadn't thought of it!

    Re Get the Patent first JB,👍
    But how will I stop certain 'reverse engineering experts' 😉 copying it Doug. Perhaps call it a vape machine to put them off the scent😀? 'Thinks' blast! I've already told them how I did it. Never mind, now we'll soon be able to buy one off Ali Express. Once had an idea for a pen with a triangular letter opener on the top end. Years later I went to a pop-up Chinese nic nac sale in a rented warehouse, and guess what was there??!!!☹️ They are obviously employing psychics to walk around jotting down peoples' ideas😮
    I also still have 5th form (1968) sketches I did for a hybrid go-kart using a Briggs and Stratton motor driving 2 alternators charging twin 12v batteries driving electric motors on the back wheels with chain reduction drives, WHO KNEW???

Two boats with one transmitter
Finally managed to get this to come out the right way up on You Tube (didn't like MP4,- came out upside down). Running the 2 boats from an HK 6ch 2.4 radio (slight crash and jostling by the Maiami at the start) . You'll get sick of it in a few minutes and fall asleep but I've put it up anyhow😁 If this doesn't make you seasick, nothing will!😊 Hit a Koi carp (Chinese sub) at 3.01!

    "Koi carp (Chinese sub)"
    Er ... that's the JDF, Japanese Defence Force sub JB.
    Didn't get seasick, but it did 'make me eyes go funny' 🤓
    This can never work for more than a minute or two cos you'd need to have absolutely identical performance of ESCs, motors and rudders (perhaps also hull forms) in both boats.
    I tried it once with my destroyer and Sea Scout - no chance!
    Had more luck 'escorting' a same scale (1/72) Flower Class corvette around the lake in the Olympia Park, Munich ca 3 decades ago 😉

    This vid is cut down from around 20 mins Doug. Each boat is totally independent of the other as one is on the left stick using one RX (elevator and rudder channels) and the other on the right stick using a second RX (throttle and aileron channels)
    I think everyone has the idea that they are on the same stick? The eyes do go a bit wonky as the camera is only a small keychain camera (pre Go Pro days) which we used to mount on planes etc, and the boat movements are quick.
    You can always change the playback speed (on the left of the You Tube logo)
    JB PS I'm sure I saw a red star on that carp!

DRIVING 2 BOATS AT ONCE
Running 2 models at once with 2 TXs for a bit of fun for a video. No one else to steer so it was just me, (not particularly coordinated though!) Sorry about the video, YT seems to stuff some of them up even though they are the correct format, (sound almost disappears as well)

    Re - Small table to rest the trannies on
    What Doug said Ken,😀 Was easier before I changed to twin throttles as I had each boat on a separate stick.

    Re - Well what do you expect livin' on yer 'eads
    Probably something to do with the space time continuum Doug, did you know the water runs the other way down the plughole down South (or up South if you want to be contrary) Mind you, the blood running to the top of the head makes us think differently (same with the Aussies, although they think slightly more left than us😊

    Re - It was just a loose idea, maybe a bit of copper tube
    I think I am just going to run out of room after checking dimensions Martin. It would have to go under the rear cockpit floor and I just have too much in there already, (2 battery packs and all the tubing)so I might flag it for now, and if I get a brainwave later I might re visit the idea.
    I agree with what Doug said about trying to get things working in such a small scale. There will be a way, just haven't found it yet. Custom made may be the only answer. If the boat had a full cabin it would not be an issue, but the low cockpit floor layout limits you a bit.

R/C Cam Boats
Using the Hobbyking Swamp Dawg as a platform for my Gopro action camera.
Managing slide, drift and wind rotation was a challenge in varying conditions, to help tame the beast we tried a few basic options !.

    Hi Bryan,

    Jaws looks very good.
    I can't wait to see it in action!
    An under water video would be good!

    I hope for not to much underwater footage as jaws is a surface runner with a lot of the shark above the waves.

40" Seaplane Tender, new build. Engine sound (original full scale engine)
Full size Detroit 453 2 stroke diesel as fitted to this seaplane tender.
I have the same Rev counter he's using by strange coincidence!

40" Seaplane Tender, new build. Quest for the correct engine sound
Found a sound by accident which sounds quite a bit like the sound of the GM Detroit 453 2 stroke diesels fitted to this boat (still has these today) Vid from cockpit is the sound I discovered while mucking around with some old electric motors, and my new voltage controllers which just turned up.
I'll add the link to the real engine for comparison (next post here). Sounds to be revving really high but being 2 stroke it's only doing around 2800 rpm!

    And the prize goes to..., perhaps if I (thr) hum along Doug?😊 (see reply to Martin for answer) It's real hard to get just the right sound to match a model (the sound units I have are not too bad) but there must be ways of doing it without having to spend lots of money on complicated sound units with set programmed sounds. In the case of my sound units, they are real engine sounds, programmed to be proportional on internal SD card but they don't quite match the model). A lot depends on the internal volume of the model (resonator), sound unit and speaker/placement.
    The search will continue for a cheap alternative.

    I spent some time in the Middle East on H.M.S. Nubian ( Tribal class frigate)
    H.M.S. Relentless ( Daring class) followed us back to UK. I remember days and days of watching her just behind us in the Bay of Biscay, which lived up to it's reputation. I always thought the Daring class was the last warship that really looked like a warship with her twin forward gun turrets.
    Mind you I think you would have wet feet 24X7 on her waist decks.
