Built from a .PDF plan I found on the net, this 22" Outrigger Hydro sports a Hobbywing 3600Kv Brushless, along with a Hobbywing 60A esc, a 5000mAh 11.1v 45C LiPo, and an Octura X435 Prop connected to a Struuder from Prestwich models.. it weighs 930g without the battery, with the battery, she goes 1386g.
Part built Models by design hull. But enough together for some sea trials.
Fitted with twin 900 motors, twin 14.8 lipo batteries and a full action electronics power package AND sound system. it sounds as well as it goes !
The size of speaker all depends on available space. if you fit the biggest possible speaker Im a cramped position, its never going to give out maximum output, as objects in front of it will disperse the sound waves, so in this instance, its far better tio fit a smaller speaker and be able to allow free space for the sound waves to exit properly.
Obviously, if you can fit the bigger version, its gives more bass and sounds far better.
remember to install the speaker on a firm base plate and ensure this fits neatly to wherever you have decided to install. now to create the "speaker sound box". if you think of an ordinary speaker at home on your stereo or surround sound system, it is in a sealed box [or cabinet], well same applies to get optimum performance out of a speaker in your boat too. I fitted mine in the bows of the Mersey, facing the stern, and used the "not used" bow section as the sound box, you also have the deadening effect of the water, which aids the sound output out of the speaker. remember to make an "air port" in the speaker plate, to allow air "in/out" too, not too big or small a hole mind.
the better you create the sound box and make sure the space in front of the speaker is clear, the better the sound output.
best of luck.
Incidentally, I have now purchased an m troniks version, I WAS going to install in another "smaller" boat, but after listening to it, I dont think I'll bother and save up for another action system and stick the mtroniks one on ebay!
many thanks for the info I think I will go for the big base one as I have plenty of room in my boat its quite large one so won't be a problem for room if you look in the build blog section on this site you will see it.its the 60inch fire boat,I will let you know how I get on once it has arrived and fitted.
cheers for the help Arthur. you boat sound so good 👍
this hydroplane had to have major work done to strengthen both sponsons internaly as well as filling with expanding foam,this stops it from sinking in the event of a flip over and to put a little weight in the front to help keep the nose down.
fitted a tuned wrap to center pipe,water pump and also added extra fiberglass on the bottom because this was so thin it was flexing at speed and was hitting the bottom of the engine!!!!!. re-painted it too and put my own choice of graphics on.
I fitted the pulse water pump because I wouldn't be running flat out all the time and needed to cool the engine at lower rpm's,and the pulse water pump would do just that with twin inlets and outlets to keep the exhaust and engine head cool.
hI alan,
a pulse pump works off the pressure of the downward stroke of the piston, as the piston moves down pressure builds up in the crankcase bottom and with a small tygon fuel line fitted to the insulator block that the carb sits on you can tap into the 'pulse' of pressure that's created and its this that works a diaphragm inside the pump, it pumps water when your boat is not traveling fast enough to cool itself through the water intakes.
Ahoy
Here is something you dont see everyday, I built this from scratch made from pinewood. This consolidateds PB-2Y5 Coronado flyingboat, used as a trnaport and submarine patrol bomber.scale 1/72
Franklyn Day aka Boats
Ahoy
Here is model of the USS MAINE as she appeared in 1898, Please note fellas this is not a opperating model. I built this from paper and would love to share it here it is 10 inch,s long in the scale of 1/384.
HI Franklyn 👍 Great looking water line model,plenty of detail, must have taken ages to complete? Kit or scratch build? Keep up the good work. Regards GreyWolf.
Built from scratch from plans supplied by my hobby store. has a fully remote controlled operating "elevating wheelhouse" with scissor type lifting legs. operating nav lights, fog horn and twin radar units. Also has remote operated forward winches for attaching pusher barges to the bow pusher posts. fitted with twin kort nozzles, handles a treat, steers well and could certanly push more than 3 barges!
HI DAve. I found a cute little geared motor with a nice set of swappable gears in Maplins, made by MFA. it has a 3v motor but if you set the main driveshaft up centrally, it then allows you to have 2 identical "winch drums". to operate the motor "in/out" I used a couple of micro switches set up on top of a servo, so I then use the side/side on my left joystick for example, afterall, you only really need to operate it when setting up to the barge once in the water and again when removing the barge before lifting out again, but ciould work for almost any "winch" operation.
I am unable to post pics to this message/reply, but will post detail in the electrical section, make it easier.
That is avery nice pusher, sir. I have built one VAC-U-BOAT 22" HiPS kit and a 35" Dumas American Beauty. Both were given my boat shop's paint scheme (ILLINIWEK MARINE). I am multitasking on a couple boats, and one is another US Western river towboat, scratchbuilt up from a salvaged Dumas
Am. Beauty hull. (That hull was temp scrapped when my xacto knife got away from me trimming the deck knuckle.) My plan is to fit a telescoping
pilothouse which is common to upper Mississippi, Illinois, Ohio rivers.
My dilemma is the method of operating the pilothouse lift; can you advise with any info please? I thought of a linear servo w/worm gear maybe.
HAVE A SAFE RC BOATING DAY
based on a Lesro kit of the MK21 Sun tug. This slightly later version was fitted with fire monitors for handling tankers in the thames esturary as well as normal docking duites of liners and freighters.
Fitted with a decaperm 3:2 geared motor and twin 12v 7amphr batteries, it can run for several hours, even when towing other boats around the pool.. Fog horn installed, lighting system, working decca radar, Illuminated map desk and decca unit on the bridge.
this is my new build of a 60inch fire tender,bought plans from a ebay member in canada who resized them to 60 inch very large boat,don't know what size motor or prop to install so if anyone can help please advise me. would a 60 to 70mm propellor be okay on a boat this size? I will post more pics as I progress with the build. this boat is now in the build blog section with more pics of build
Yours will be a jolly nice craft when completed, its large however, and with the proper turn of speed it will use up a lot of water space very quickly. My fireboat is a mere 46" propelled by two Johnson 980's on 12v but it fair gobbles up water space and my local pond at Sheringham is completely useless.
Keep up the good work.mdlbt.com/sys_files/graphics/smileys/027.png
I agree, that's why my 46inch is kept in Tynemouth where ther is a large lake compared to my local club in Warwickshire. Still it gives me the excuse to have multiple models of different sizes and my Derek old mum loves the idea she keeps my boats for me in the NE. Too muh information ????
HI fellow modellers, Another model from the RADMC fleet at the fleetshaven workshop and boat yard in Ponthir.This model was scratch built using a fibre glass hull and plan obtained from a fellow modeller at the Bridgend Show in 2007. The front door and some fittings are made from plastic card and tube, decks are from ply and timber. On board figures are from the pound shop and car boot sales, modified by myself. The on board tank and half truck are RTR models that I have modified their looks to fit into a WWII theme for the craft. This craft has twin drive, 400 motors via 2.5/1 gearboxes. I tend to use both sticks on the TX for drive as this allows me to turn the model on a six pence.The dispatch door works from a rotary pot on the TX and via a rotary sail winch servo in the hull. I have just modified my Planet 5 TX to allow me to change my radio gear in this craft. This model has had meny trips on Cwmbran Boating Lake and at shows the society attend during the year. Still haven't allowed the tank or half track to run off the landing craft up the lake side slipway. one day I might get it on video. Hope you enjoyed the photo's. Regards GreyWolf
