Motor problem by pmdevlin Fleet Admiral!   Posted: 13 days ago
Hi Richard, that lead acid is way too big and heavy. I Remember going on hols as a kid, car was loaded up, all family, roofrack, deck chairs, tent and so on, and Dads old Moggie Traveller would barely climb the Welsh hills! Same here, its just dead weight, ideal for a tug etc, no speed required, and ballast needed. This boat wasn't any slouch in its day, As Havelock says, it was originally built as a ic powered model so could stand being heavy. To achieve balance, its a matter of moving things around, not adding, so just move things forward, you will be surprised how the weight increases once you start adding Deck clutter, fittings and so on. Lightweight, is good. Your comment, stood up in the water at half throttle isn't going fast, its just bad weight displacement causing the bow tyo be too high. That setup would never have been that fast, the motor/battery combo will never cause a heavy ply boat to be going that fast its standing on end Couple of things to consider. Your nimhs, how many times have these been cycled, and what sort of charger are you using? A reasonable charger will give the information, if I know what you are using, Ill advise accordingly as you might not be getting the best from these batteries what prop are you on Think of an rc plane (if you fly them its easier) If the cog is too far back, the nose is pitching up, and its almost impossible to control, it almost porpoises in the air, and is very bad. COG is vital on a rc plane, nose heavy is better, only because its more controllable. COG is equally important with a boat, but harder to see the implications, the hull will give us false info, such as if the bow is up its on the plane, no, not necessarily, its not planing due to speed, its just out of balance. Shifting the weight radically will let you see this, sorry for the ramble, Wish you where closer to me I would love to help hands on👍 Ive tried to find a suitable video of my Huntman to display what I'm rambling on about. This video is poor quality, but it displays that boat moving very fast (25mph with on board data logger) but look how flat it is, its planning, as the forward 1/3 of the hull is out of the water, but its not standing on its tail, this is because its balanced. You boat is pretty similar in design to this so whilst you wont want to go this fast, the picture should look the same. This Huntsman weighs 6kg with batteries (lipos, you will NEVER get a nimh or lead acid to do this) and is 4 foot long, so quite a heavy old girl first constructed as an IC model in the early 70's. https://www.youtube.com/watch?v=e5-YmmElIfk&t=34s and here is a picture of my 3 foot aerokits fireboat, bow up, is it planing, no, its way out of balance, it wasnt actaully going that fast Hope that helps Paul

rotating radars off mast by seafarer Chief Petty Officer   Posted: 14 days ago
Thanks Dave, you've set me off on another adventure into the unknown but I think I'm learning....do I need the Arduino UNO controller and could I control two motors off it (it doesn't matter if the speed is the same ) . If I don't need the controller ,could you explain a bit more about using the POT (presumably a potentiometer?)

Motor problem by reilly4 Lieutenant   Posted: 17 days ago
Richard, If as you said each blade from shaft centreline to tip of blade is 30mm then it would not matter if you had two blades or ten. If the radius (your measurement) is 30mm then the diameter is 60mm. Perhaps you can remove the prop and place it on a flat surface so you can see the swept circumference when rotated.

Finishing line in sight! by Skydive130 Admiral   Posted: 21 days ago
Had a couple of hours of good light after work so cracked on a bit more. Finished the last Bulwark and all the splash boards (if thats what they are called?), sanded and sealed. Last job of the day was to spend some time masking the whole hull leaving just the deck available for a few coats of Halfords grey primer which will be the final deck colour. No more work until saturday now, but next thing is to continue masking leaving the Bulwarks available for spraying white. This to be followed by stanchions, rope work, anchor and some weathering before a final few coats of laquer (Less the deck that will be matt varnished. Still a few jobs beyond all this inc bath test and ballast as required and a few other bits n bobs, but she's getting there!

Aerials etc. by Gdaynorm Commander   Posted: 24 days ago
I have just gone through all my pics. On one there is what looks like a 'mattress' style rotating aerial atop the stbd forward mast. I think I shall string wire along the rear three masts both sides. Does that sound likely to be accurate? My wife and friends tell me to forget total accuracy as no-one seeing the model will know any different. Trouble is, I shall know.

Varnish by RNinMunich Fleet Admiral!   Posted: 1 month ago
Exactly Haverlock👍 wet with washing up liquid between coats is what creates the polishing effect and final gloss. Something I learned the hard way back in my car restoration days. Dry sanding creates more of a 'silk/satin' or worse matt effect. 😎

Propulsion Hegi Revell Fairplay V tug model by Radiosailor Sub-Lieutenant   Posted: 2 months ago
Hi AllenA, LOL! I think you're referring to my post "Local Boatshow" in the Boat Harbour section. Doesn't matter. Happy to read that I'm perfectly fine! I'm just new here and have no idea how active this forum is. I happened to stumble over this forum while searching RC boat photo's on the web, and thought: Well why not drop a question here. (not knowing at that time that I would spend half the afternoon posting pics of my own fleet...and I haven't even finished yet...) Back on topic: I'm curious to see what advise I get over here regarding the Fairplay V. I might even keep up a build blog over here. I like the classic - almost yacht like - sheerline and superstructure. And this model is compared to the Banckert, Bugsier, Kalle or Torben tugs slightly wider and heavier; which will give this tug just a bit bigger wavepattern...

What paint type by RNinMunich Fleet Admiral!   Posted: 2 months ago
Hi Scotty (How are the dilithium crystals doing? 😉) Was expecting one of the vintage boat / Fireboat modellers to jump in here! Since no one did here's my two-pennyworth. Basically I consider the actual paint as cosmetic and not primarily to seal out water. Unless you want to use 2 part epoxy paints, which are not so easy to handle🤔 I used it on my U26 sub and it was pain in the you-no-where. First I would use sanding sealer inside and out. Then EzeKote or ClearKote inside and out. Especially where you want to let the planking shine! 👍 From Deluxe Materials - available Down Under from - see pic. this toughens the hull and gives added protection against knocks and bangs. Many of us then paint the inside with Hammerite, colour and texture, hammer or smooth etc, personal choice. This looks neat and is easy to keep clean. Out side acrylic is the easiest and most pleasant to use; water based so the painting tools are easy to clean with warm water and no dangerous to health or inflammable solvents. Easy to airbrush too😉 When the colour coat is finished and good an' dry you can then apply an acrylic clear lacquer coat, matt, silk or gloss as you wish. Hope this helps, cheers Doug 😎

Hobby Engine Richardson Upgrade by NPJ Captain   Posted: 2 months ago
They say " whatever floats your boat" so today I did just that with the Tug in the bath.................. I compared the affect the new battery 'buggy type' 3300 on water line with the standard battery. Although three times heavier, the larger battery seemed to make only slight difference when placed in the centre, fore and aft. Whether I can move stuff to put it there is another matter. Same with the computer fan. But worth a try I think. So next bit of available time needs spending on really doing some damage inside! NPJ

PT109 Refit by RNinMunich Fleet Admiral!   Posted: 2 months ago
Hi Maurice, no don't worry about the stand. I'm going to make an 'Allen_A tissue box special for it' 😉 Separate blog to follow shortly 😁 Yep the 37mm should arrive tomorrow, which is fantastic service considering I only found and ordered it this morning😊 Yep I'll leave the motors and ESCs as they are for now - see how it goes and if I can keep up😉 Pale green paint and clear matt lacquer arrived from Italeri today and ColourCoat MTB Green is on order. I think the first thing I'll do is gut her (don't wince) and seal the hull inside with EzeKote. "Hey ho, hey ho it's off to work we go"😁 Cheers Doug 😎

PT109 Refit by RNinMunich Fleet Admiral!   Posted: 2 months ago
YooHoo! Found a 37mm kit at right scale, and ordered😉 Now, where can I get some miniature baked-bean tins for the depth charges? 🤔 Gisela's Doll's House perhaps 😉 Hi Boaty, Ta for the info, I'll watch the temperatures! Thinks, must get a temp sensor or two for the telemetry feedback! Oh Woe where does it all end??😲 I bought my PTB from 'DadofBasil' complete with two 20something brushless. I intend to run it on a 2S LiPo 4000mAh. Humbrol paints are as rare as rocking horse droppings out here, but I found a source of the original WEM ColourCoat US26 MTB Green😊 Also have a paler version, like in the photos above, from Italeri (arrived today) so can (hopefully) achieve suitable sun-fading / weathering effects. 'Standard' anti fouling (matt brick red!) for lower hull like you! I want to build as it was when she got crunched by Amagiri, as far as possible considering all the partly conflicting versions and reports! For instance; Still trying to decide whether to leave the mast off completely or just fold it down! Cheers Doug 😎

International Model Boat Show by rolfman2000 Admiral   Posted: 2 months ago
Our club is on the list of exhibitors for that show. Although we haven't "officially" been told about it. No matter, I will be attending on, at least, the Friday of the show (as I'm not good in big crowds). Anyone else going, and maybe we could have a little get together ? Here's hoping, Dave W 😊
