    Wow I'm back to remembering my desire to have a shark with my orca. I tried everything, towing, shark at side, shark at front, and it never hit the spot. I then thought about an rc shark.
    At the time Glynn guest had a plan I'm model boats mag for a simple submarine called nixie. My plan was a dorsal fin over the tower, I wanted the fin to surface and dive. It seemed a simple build, but nixie has currently Sat on the shelf for several years. I just couldn't get it to operate correctly.
    I see now on ebay etc there are rc sharks quite cheap, but I bet they don't work in a lake, more for paddling pools and bathtime!
    If anyone can build me something I would take it!

    The plans where sourced from original many years ago when this site was first developed by Stephen and was dedicated only to the vosper fireboat crash tenders. Peter timberland one of the first founder members had the first copies, and we passed them around between each other. Most are poor quality unfortunately however there is enough info on this forum to make very accurate reproductions, I would suggest look at the build blogs, I have a very detailed one from several years ago that contained many photos and plans, hope that helps

    Yes I experimented with a load of props, x, s two blade, 3 blade, and so on. Using data logging by eagle tree I was able to compare actual results, run time, amp draw, speed and so on. The x 2 blades where very good, I think the best size was 52mm, but that cleaver prop was specially commissioned by Simon, gosh cannot remember the company name! But he makes brass props. At the time he had some props in development and used me to try a few. The design of the blades gives it more push and less cavitation, and it looks nice! I sent him all the data. I can also change the gear ratio as its belt driven to suit the lake I was running on, fast acceleration and lower top speed on a small lake, a d better top speed on a big lake. I love the meddling and testing. A single screw v shape very heavy hull single screw will reach a point that it's reached its maximum speed, I got there with this boat!๐Ÿ‘

    Hi,

    I don't come here very often these days, picking this thread up a bit cold, attached is a pic of my prop, its called a cleaver. I tried many props, I like meddling, better than just sailing. I had an onboard data logger that measured amp draw and gps speed. Propguy helped me a lot and is worth a call if he still trades, I always said I would convert this boat to twin screw but never got round to it. When reaching max speed which was 25mph, the hull gets very unstable, as it want to roll over! Its a veron Huntsman 28, 4 foot long

    I made my own smoker, spent ages trying to create black smoke, carbon, diesel oils, and so on, even bIts of rubber!

    rubbish quality video but gives you the idea, its wire from a hairdryer wrapped around a piece of dowel covered with some roof insulation soaked in oil in a metal box, with a small pc fan to blow the smoke out, juts need to remember to fill up the oil via the exhaust stack every 15 m ins or so or the hull will get hot and then you do get black smoke. !

    here are the colours, taken from Vosper original plans. Like I said earlier, the cabin sides are darker, but thats if you wanbt to be real picky!
    Deck was painted in cerrux none slip paint. You can achieve this by first dusting with light coats a textured paint, till you get the effect you want, then paint over in bs631 or whatever you use. Using modelers license ๐Ÿ˜ we all paint our cabin tops in a real glossy finish, can you imagine that actually happening! all the crew would fall off๐Ÿ˜† then same with the hull, by the way, I did this! just because I thought it looked better

    Hi,
    regarding the colours, I was very friendly with Peter Dimberline, and Peter Henshaw, both where original members of what was the Fireboat website, I was not far behind them!. PD knew someone that served on one of these boats, and between the 3 of them, they found the original Vosper plans etc, one of which had the paint codes.
    BS639 was the deck colour, but the cabin sides was a darker grey, I dont have the code to hand at the mo. PH painted his boat this way, and it just didn't look right. I painted my 3 foot and 4 foot using BS639, but we reckon over time the correct shade was lost as time went on, you can see whilst its the correct code, it looks a bit green. I went to great lengths to get things right, but we can all use a bit of modelers license to create what we want. There where only two of these boats, they where not mass produced, it was infact a failed project as they arrived too late. The flying boats they where supposed to support where pretty much at the end of their useage

Im not a fan of halfords paint, the high build primer can also cause issues.

You can programme without the card, but its a fiddly affair, following series of beeps etc. As said, plane dont fly backwards (however there are a couple of water planes that do have reversing esc) I would sell it, and buy a dedicated boat esc, some even have the option of water cooling

    Hi all,
    tried to sell this some months back, no interest, so I decided to do some improvements, to make it perform better, and easier to use. I removed the triple screw set up, and replaced with a single motor. To make things as easy as possible to use, I have installed a Graupner 700bb brushed motor. You can use any battery chemistry with this, and it offers a wide voltage range. I have also removed the scale rudders in favour of slim ones. As its gone from triple to single screw, the prop wash isn't over the rudders now, so there is possible improvements to be had, I just used what I had to hand.

    Price reduced with two options

    1/ all running as per video, Ill leave the orange receiver in if someone is using spektrum transmitter ยฃ150

    2/ no running gear, just bare bones boat ยฃ100

    This is a bargain for a real nice hard grp plastic model. It has nice detail, and no wood rot or delamination worries. It will offer a nice project for someone who wants to make it run and perform to suit their own style. I will include the original 3 motors, props, shafts etc so if you want to go back to triple screw you can.

    I can deliver to Wirral or Cheshire (contact me first) or arrange a meet up (all subject to social distancing rules) if you are still housebound subject to none refundable deposit as I don't want messers. My latest RC Plane project arrives on Friday, I desperately need the space and money!

    Hi all,
    now things have started to relax somewhat, I'm back to work, travelling between Wirral and Crewe, so can now offer a drop off to Wirral or Cheshire (please ask first) to any prospective buyers, it can be dropped at the end of your path, subject to full payment in advance, this offer is not to look, if you need to look first then its a trip to north Wirral.
    I need the shelf space, and the funds for something else, so I want this gone now, so price reduced to ยฃ180.

    simple home made:

    small metal box, maplins used to sell these, you can pick the size and shape to suit your model, ebay is full of them.

    get a small fan, the sort from a pc etc, again, size to suit, and it will run on your drive battery, so when buying, check the operating voltage. Cut a hole a bit smaller than the fan in one side of the box, the fan will drive the smoke out. Between the fan, and the box, have a piece of thin plastic, it will need to move to make the hole bigger or smaller, to be adjusted when testing so you can limit the amount of air entering the box via the fan, as the fan speed will be constant.

    Drill small hole either end, make up two rubber grommets for these holes. Next, pinch the heating element wire from the missus hairdryer, or something else!. make a wick from a wooden dowel, wrap (coil) teh wire around this, and have it enter and exit the box, the grommets are so the wire does not touch the metal box, as it will short out. using ole fashiooned loft insulation, fill the bottom half of teh box, and rest the dowel on this inside the box.
    soak the insulation, and the dowel with baby oil (I moix baby oil with disco smoke fluid, but you wont be able to get this, baby oil works fine)
    Using a spare channel on your transmitter, a switch on/off, make up a microswitch of some sort so when you flick the switch, the microswitch makes the circuit. The feed will be either end of the heating element wire. Now, the supply voltage, and length of wire, will determin how hot it gets, this will need experimentation on your behalf, too hot, it will just burn out, too cold, it wont heat up.

    Wire the fan into the circuit, so it comes on, the fan will blow the smoke up the exhaust etc, or whatever you use.

    Thsi is the basic principle of the rc tank smokers, its just hot oil smoking. Every 15 mins or so, you will need to wet the wick again, I use a syringe and just pour down the funnel on my boat.

    There it is, a bespoke smoke machine, using probably thingsd found around the house, or bought very cheaply

    My box is directly under the exhaust stack, you could use tubing to direct the smoke

    Hi Robert,

    Im assuming that picture is generic, its not your finished boat?

    Brushless motors are fine for any application, the choice after the spec is outrunner, or inrunner, the former probably the cheaper and more readily available. Just ensure that you have nothing danging around next to it as the outer can rotates, very fast๐Ÿ‘
    Water cooling only if it needs it, it probably wont, however you will find that most specific boat brushless escs will have water cooling, if it has it, (hobbyking are best source) then use it, as some of the hobbyking escs rely on this as they don't have cooling plates inside. Its a simple thing to plumb it in, make you own water pickup, and exit if you have the tools, the shop bought ones are cheap, but sometimes look ugly. Simple bit of brass or ally tube, between the prop and rudder, bent to face the water from the prop,epoxy into the hull, some plastic tube (you will have all this from planes!) to the esc, then from esc to an outlet, at transom tends to be the nicest looking!

    Paul

    Consideration is the motor shaft diameter, and the propshaft as you will need a coupling, that's capable also of the higher revving motor.

    SHG Marine are a model boat parts dealer, they sell all of the couplingsd etc, propshafts, and usua;lly have a good srtock of plastic two blade "x" props, grab a couple to test with , 45mm, 50mm I woulds suggest
    Pics for reference, the HK escs in the pics are bullet proof, I made water cooling plates for the motors on that boat, it didnt need them, and exited the water pickup via the two engine exhausts on the transom, looked cool when the boat was running!, inside the boat, I used alloy rod instead of plastic tube just for ashthetic reasons as it was a four foot boat and a long run from teh pickups to the esc's

    great reply Doug, you got to the specifics there.

    In Summary Ray,

    keep your esc, its fine, but is it for brushless, and does it reverse? how many cells will it take?

    motor, needs to be in region of 1000kv or a bit less to haul the heavy hull, and consider its only a single screw. size, Im not sure, poss 38 to 40 (the first two numbers of the spec of the motor, someone else can get to this)

    if the esc is rated for it, run 6 cells, two 3 cell packs, minimum really needs to be 4000mah, and a good c rating, 40c upwards, or the lipo will drain too quick, and starting point for me would be cheap plastic "x" props, at 50mm, 52.5mm and 55mm to test.

    5mm shaft, 4mm is marginal

    Hobbyking is the best place, look there, you dont need to be buying expensice equipment when you are at this testing stage.

    this will somewhat replicate how I arrived at my Huntsman set up, same size, similar weight, although the deep v hull of the Huntsman makes it handle very different.๐Ÿ‘

    Unless someone comes on with evidence of what they use, and the results, this is it. Have you looked at the boat harbour section, see what people have?

    Ray,

    I could be wrong, but imo the 2200kv is way too high, lower kv will give more torque, high kv will give more revs, if you are saying the boat will be heavier than my Huntsman, which has a 900kv, then your 2200kv will just rev its nuts off! you need the torque to get it moving, and to spin a bigger prop, that high kv will not spin a big prop. You can run two 3 cell lipos, wired to double the voltage, but tap into one battery supply to power other things, so then they are on 3 cells, not 6. Also by splitting the battery source, you can balance the boat, as in the pic. I would imagine tyou will be operating the accessories on spare channels from the receiver, if that is the case it wont matter what your drive battery is.

    I remember finding that build, his work was real nice, my hull actually isn't Orca, its been modified to look like it, you can tell from the rear, but close enough to fool people I suppose. Nice work with all the detailing, don't forget the smashed window! its the little things that count, that is if you can be bothered with the relentless statements at the lake of "did you know the window was broken, why don't you fix it"!!
