Offshoot RC Models/Drone Hobby Thread

Heading home after only a few runs, too windy and choppy again. :face_with_diagonal_mouth:

I took a video of a large Hawk that was chasing and dive bombing the boat up and down the Weir for a good 10 minutes, which was a bit of fun!


Didn’t get much time on the water, but at least I gave the local wildlife something to do! :stuck_out_tongue_winking_eye:

Maybe have a play with this site MetEye

Fiddle with the settings in left hand side then gives you a good idea of wind speed and direction. Helps me anyway :man_shrugging:

Cheers mate, have used that before on occasions, but will definitely come in handy for checking the conditions at the Weir before leaving home. :ok_hand:

I was wanting to stay longer simply to run down all the battery packs I had with me, because discharging them back to storage state has taken all afternoon, and I’m still going, with only 4 out of 12 packs done so far. :face_exhaling:

Problem is that the wind picked up even harder not long after I took that video of the Hawk, and the waves actually started White capping.

Dickhead me thought ā€œjust take it easy and she’ll be rightā€ā€¦ famous last words as I lost the Hatch to the TYLOSAURUS AGAIN, even though it was taped, it went deep under a wave and eventually resurfaced without it. :face_with_diagonal_mouth:

Luckily I had only just added sticky back foam to the hatch lids the day prior, so at least they would float and eventually the wind and waves would push them onshore.

Which worked a treat today, even though I had to go for a long walk to find it and wade out in the freezing water to retrieve it, at least I still got it back again. :raised_hands:

Back home and adding extra foam to both Hatch covers.

But also snapped off the LHR bottom hatch lock and the tongue at the front where it clips into the Hull… because the battery had wedged itself under the hatch lock mechanism and I couldn’t get it undone until I pried open the opposite side to provide a small gap to be able to move the battery out of the way.

Not surprising that the battery moved though, as multiple high speed flips, barrel rolls and deep sea diving will do that!

All glued back together now, and definitely going to be staying off the water when the conditions are so rough, its simply not worth the damage and losing parts for. :disappointed_relieved:

It was probably the scaled down equivalent of taking a 5 metre runabout out in a 1.5 metre swell. :laughing:

We’re lucky to have Centenary Lakes up the road from us… not huge but really sheltered, dead flat. My mate takes his RC yachts up there now and then with his grandson. I tried RC sailing once… too complicated with all the RC motors driving trim winches for me. :laughing: There’s always Scarborough and Newport basins that aren’t too far away to float your boat in too. :+1:

No rough water to deal with… just have to watch out for the crackheads at Centenary Lakes jumping out of the bushes to steal your boat then running down the road to the Hippo pawnbrokers with it. :rofl:

Sneaky little solution with the foam blocks on the upper deck too, Doc. :clap:

I’ve often seen the remote control yachts , near the Newport shops.

Yachts only, no speedboats…

Probably cranky old homeowners, who’d call the water police, if your rc speedboat busted 6 kts…!

:rofl::rofl:

Oh man… those old boys down there at Newport are pedantic little blokes.

My mate is an ex- boatbuilder, he scratch builds his RC yachts. Laid up fiberglass hull moulds, the lot. I went down there with him for a sail and he made the mistake of talking to the old farts who were having a sailing comp down in the basin.

All these crusty RC yachties came over one at a time and picked the absolute living shit out of his yachts. Keel length’s not compliant, beam’s too wide, blah blah blah… he left pretty deflated. :roll_eyes:

My first thought was ā€œthese are RC boats, matey… get a life!ā€ :rofl:

I’ll go there on my JetSki…and give em something to complain about…!

Thanks for the comments, as is great to hear of the old boys getting into the hobby in their retirement and having fun… except for those ā€œknow it allā€ circlejerk types, which I know only too well through the modified/classic car scene having the same type of ā€œknow better than thouā€ idiots! :roll_eyes:

Yes you are definitely on the money about the Scale of the waves, which would have been closer to a 3m swell!
The need for some pretty calm waters to be able to get the most Performance and enjoyment out of these boats is pretty important, but also surprising just how much rough water they can actually handle.

Would be awesome to have some of those nice sheltered City ponds around here, but only have the Drakesbrook Weir and even larger Lake Navarino Dam to run on, and they are both massive bodies of open water in the hills that rarely ever get millpond type conditions. :face_with_diagonal_mouth:

These RC Boats are LOUD too, not as bad as Petrol/Nitro boats, but would definitely upset the Karen’s in a City Park pond, and being so fast, very dangerous in any areas where other people or animals are present.

Biggest issues I have are the bloody Shags, which pop up to the surface from out of nowhere when you least expect it.

At least all the other Ducks/Geese/Swans etc. stay on the surface, but have had a few VERY close misses with Shags already… and the Hawk dive bomber threat from above! :rofl:

Getting Evil thoughts being unable to get out on the water with the current weather conditions. :grin:

Tore apart my home made 4S battery pack, as I came up with a plan to be able to run the two individual high capacity 2S batteries in the psychopath Mad Flow Boat either side of the hull, rather than the heavy single 4S packs up front upsetting the CG and handling capabilities, to allow me to move each pack fore and aft to fine tune the CG as required. :ok_hand:

By splitting these two packs, I can now safely run what totals to be 14.8V, 5200mAh at 50C ratings. :ok_hand:

Also got stuck into the UDIRC ARROW, removing the battery tray and chopping out the mounting points inside the hull, exactly the same as I did with the TYLOSAURUS, along with checking out a good placement for the aftermarket SKYCOLOR 150A ESC and dual batteries in each side of the Hull for either 4S or 6S applications.

Picked up another couple of packets of Velcro strips to fit into both the ARROW and Mad Flow boats to allow shuffling of different components to be able to get the weights and balances right. :ok_hand:

Plenty of aftermarket performance spare parts already in my collection, and only a matter of testing and tuning to see what works the best.

So yeah, just another rainy day and got plenty of gear to muck around with, but will be a while before getting back on the water to test out the modifications.

Love this video @Friendly_Fire to give a bit more of a Scale perspective of these Speedboats.

It’s a great little video, but as a builder and modifier, sends shivers up my spine at the same time. :hushed:

The irregular ā€œwindingā€ sounds coming from the driveline, which is also causing that terrible ā€œporpoisingā€ of the boat is due to this fella not leaving the required clearance gap between the Prop drive dog on the flex shaft.

The flex shafts are spiral wound in either left or right hand rotation, and shrink in length as the windings tighten up under load.

If you don’t leave about a 1mm gap between the Prop drive dog and the flex drive tube, the cable will shrink and jam the drive dog into the back of the shaft under load, causing this HORRIBLE sound and on/off drive to the Prop as it binds and releases the whole time it’s running. :face_exhaling:

It’s a nightmare to watch the rear facing camera seeing the Hull of the boat dead smooth, but when you look at the outboard engine cover, you can see it violently loading and unloading in tune with the engine revs trying to push through the cable binding. :disappointed_relieved:

I love watching these videos, but at the same time is like fingernails down a blackboard when people review stuff without applying the most basic mechanical knowledge such as setting tolerances, greasing flex cables, setting throttle or steering parameters or adjusting trim tabs properly… and then whinge about how shit house the Boat performs. :face_with_symbols_over_mouth:

Still a cool scale view of the Boat on the water, but my version is at least twice as fast as this and doesn’t sound like an old BetaMix. :rofl:

I thought the solution was chuck a big block in it :rofl:

NB: not watching the video as I have no water nor idea wtf I’m doing :rofl:

Usually upgrade, goes the whole she bang, or there is usually trouble.

Get round to some of my ground dwelling shenanigans but work precludes me from such things. Got these beaut tyres sitting on my bench. A full suspension and intake redo for the 5B sitting on the bench, A Tamiya Frog to build , mud slinging tyres and rebuild the Clod. Oh well as I say…

No rest for the wicked :+1:

Sounds like much tinkering planned mate, which is the fun part of the hobby, but yeah that ā€œspare timeā€ thing is the hardest part.

Always said to people that you can always find, save, borrow, make money for a project … but you CANNOT do that with Time :disappointed:

Amen, I’ll get around to it, when that rainy day comes cough cough :rofl: :+1:

I keep sending shittonnes of rain your way, but I think our Wheatbelt keeps stealing it! :roll_eyes::grin:

Can you spare $800 for 1 tonne of hay from your way. Ah I won’t go on had more than enough convo about that last night. Quite funny actually. All I needed was blabanese to sit in but he might not be alive today :rofl: :rofl:

Mate, if I was still in the Cattle Industry, I could have organised a backload of Hay Rolls on one of Mitchell’s Transport B Doubles, as we used to do for our Eastern States Farmers quite regularly when times were tough. :+1:

Unfortunately been out of that business for quite a few years now, and the old Driver’s I see in Town have all retired since to hand the reigns over to the next generation of younger drivers.

Calling South Oz ā€œEastern Statesā€ sounds funny, but anything the other side of the WA border is called Eastern States! :rofl:

Cheers mate, I got this :+1: I think. Appreciate the offer and concern but well beyond the point of no return. Do appreciate it.

Pfft call me eastern again, that pond of yours… :rofl: I’ll be skinny dipping in the fkr.

Well technically you are Eastern!
If you were Western from us, you’d be skinny dipping the whole time, or speaking Left Handed Swahili! :stuck_out_tongue_winking_eye:

I thought I already do a good job at left handed swahili. Specially when that liquid gold flows :rofl: :+1: Speaking of which :beer: I’m only getting 10mpg in this drought, might need to clean my air filter out I used to get 20mpg :rofl: :rofl: maybe a blocked jet :laughing:
