MAS 562 update by CB90 Commander   Posted: 21 days ago
Skinned the frames added deck and splash rail also started on cabin and superstructure, added rudder and installed twin brushed Graupner 600 motors via Graupner style direct couplings. Motor mounting system through a bulkhead gives extra support to motors which mount on to end of the shafts. currently adding a rudder servo mount, as rudder is a close copy of the real boat's and still functional.

Scudder by Grumpy1949 Sub-Lieutenant   Posted: 28 days ago
Vic Smeed plans of a rather ugly twin pontoon hydroplane air driven. Runs a 35 ic but will have a brushless 300w turning a 8x6 electric pusher. Water rudder pivot fwd of prop thrust line. Photo shows most of the detail with styrofoam flotation built in

Any clues? by aanside Sub-Lieutenant   Posted: 1 month ago
"This is certainly NOThe the model of a Thames or Coastal barge hull" I had come to that conclusion. Researching typical twin masted vessels with that sort of beam (thereby ruling out most schooners) it could be a Brixham Trawler or some kind of ketch. One suggestion was a Moray Firth Scaffie but I need to go to one of the local museums to see if there is a model or a drawing. Interesting clue - the rudder post is carried above the deck. I guess half the fun is trying to see what I can make of it and then get it on the water.

H.M.S. BRAVE BORDERER by RHBaker Fleet Admiral!   Posted: 1 month ago
Just to clarify. Shipping was only 7 days to Canada, manufacture slightly longer. Examined the hull closely and was pleased. It is dimensionally accurate and robust, but light. It had also been reinforced in strategic areas and trimmed to the correct deck line. My many questions to Christian Sheppard – Capurro of MTBHulls were quickly and knowledgeably answered. A company I would recommend others. Reviewing the build blogs and U Tube videos of the both the Brave and Perkasa models, shows most use either single or twin screws. The original vessel had a triple screw contra - rotating layout. Experience from others suggests the third screw just adds weight and complexity, but little to the performance. Nevertheless, it was how the Braves were built, so that was how it would be. Christian gave several suggestions for other modelers who have built this vessel. Contacted them and was readily provided with information and advice. The finished weight of this model is important and a target of around 6 lbs recommended for a 1:32 scale version. This is to achieve the potential performance. Plans for drivetrain are 3 x 2835 4500kVa brushless motors, direct driving 3 x scale 3 blade 30mm screws. Decided use a single Li-Po battery for the best performance with minimum weight. It was suggested three batteries, each powering a single motor would be the best layout. After some research, concluded this would introduce a weight penalty and was discounted. There are various ideas for the best drivetrain. Unfortunately none for triple screws. Decided the best approach would be to fit the bare hull out as planned, then try it. Leaving all the finishing features for later. A contact in Australia had already done this using a single screw layout and kindly sent pictures of his hull layout and then under test. Very informative. The positions of the rudders, propellers and shafts are established by the scale dimensions and were permanently installed. Everything else was to be temporarily fitted, so it could be moved or replaced if necessary.

British Air Sea Rescue Launch by deepdiver Commander   Posted: 2 months ago
Hi I also went and got this model, that would have been about 18 month's ago, I have still not finished it. Could not get anything to fit right, so in the end I just went for it, twin rudder along with twin props, 😱 just hope that it will work O.K. FRED

here we have some pics of the electrics as requested the first pic is of the mtronic 650 motors for main drive. second pic is of the twin rudder control. the third pic is of the water proof voltage dropper and connections for 5v power supply to some of the aux, Ron

Interceptor by CB90 Commander   Posted: 2 months ago
[Score: 8/10] 24"/2000g Interceptor Capable of 15mph and a runtime of 10mins Single Propellor (2 Blade X Type 35mm) Direct Drive to a 2958 watercooled (2 Blade X Type) Powered by LiPoly (11.1v) 6Amp/h Batteries Controlled Through Unknown 200A (100Amps) ESC - Comments: Zoom 1 (Interceptor) Mono boat. Built from a Glassfibre hull, brought on Ebay for £35 the hull is a slim mono racing type with a self-righting side cabin it runs a 1400W 14V 2958 4200KV Brushless Motor and 29-S Water Cooling Jacket with additional air cooling fan. I did not want to use a flexi drive as high maintenance and prone to failure so the shaft runs via two universal joint one at each end. the propeller is a 38mm copper alloy The ESC is a 200A and water cooled the twin rudders supply separate water one for the motor and one for the ESC. The rudder are positioned to reduce prop-walk and are hinged to prevent damage if hit a object in the water and ride adjustment. Turn fins and trim tabs for ride adjustment were provided by a spares kit for another boat. also foamed and added an inner sealed hatch, a rubber bump strip and safety loop. The Boat is fast and over-powered used at half throttle, may use a 7.4v lipo instead, the self righting works well. 20th April 2018 while running on 11.1v the boat stopped, no response on retrieval It was found that the manufacturers battery connector had melted and the connection lost see later pictures. the battery was made by FLOUREON and was a 35C with 5500mah capacity the 80A fuse had not blown.

Command Boat 90 by CB90 Commander   Posted: 2 months ago
Scratch built at 12th scale from pictures and profiles of the internet. The boat was originally built in Sweden a class of fast military assault craft originally developed for the Swedish Navy by Dockstavarvet Speed: 40 knots (74 km/h) Draught: 0.8 m (2 ft 7 in) Length: 15.9 m (52 ft) Overall; 14.9 (48') Complement: 3 (two officers and one engineer); Up to 21 amphibious troops with full equipment Armament: 3 × Browning M2HB machine guns; 1 × Mk 19 grenade launcher; 4 naval mines or 6 depth charges . The Model I was attracted to this boat due to its great performance and maneuverability, this was mainly due to the use of twin water jets as the main propulsion, this is a trade off with efficiency. So my start point was to collect as much information as possible about the boat this involved collecting pictures and profiles of the craft from various sources. http://www.dockstavarvet.se/products/combat-and-patrol-boats... Eventually I found some plans of sort :- http://laurell.today/boats/combat/plans.html My Dad was a boat builder in the days of wooden yachts, and had showed me how to make plans and frames from a line drawing. I went about this first by creating a prototype about 24 in long out of light ply. I then created full size plans of the model to be made. Pictures of small prototype finally painted plain green. The Main model Used my computer to print out the frames onto paper, cut them out and used them as templates for the ply ribs. The construction was simple chine style, with 1.5 mm ply. I tried to build jet drives but failed to produce a effective unit. So reverted to propshafts which worked out well with better control and the boat can spin on it own axis by putting one engine in reverse the other in forward and adjusting the twin rudders. That it for now, hope it was of some interest

THE VOSPER 46" CRASH TENDER KIT BY VINTAGE MODEL WORKS by robbob Fleet Admiral!   Posted: 3 months ago
Hi Vosper21 Welcome to the forum. I put a single motor, shaft and rudder in my fireboat so I don't have any first hand experience of a twin drive system but I would think that the shafts should exit the hull at the same points as the single shaft but equidistant from the keel. Similarly the rudders should be directly behind each prop. There are members on this site that have done a twin drive system on the 46" model that can offer more informed guidance, hopefully they will chip in with some good advice. Over to you chaps ! Please consider doing a build blog to document your progress. Good luck with the build. Robbob.

THE VOSPER 46" CRASH TENDER KIT BY VINTAGE MODEL WORKS by VOSPER21 Seaman   Posted: 3 months ago
Currently building this kit but would like to fit it with twin props. Does anyone have the hull measurements for the prop shafts exits and the rudders.

Flyer 15, racing hydroplane by BigAlio Commander   Posted: 3 months ago
thank you boaty thought i might put small twin brushless motor and use a mixer to save trying to fit a rudder.

SRN 4 by Gascoigne Captain   Posted: 4 months ago
An old favourite from my hovercraft phase. Runs really well on land and especially water. Although no reverse, it will auto-rotate on the hover, so when pointing in the desired direction on with the propulsion with the brushless motor and away she flies. Realistic in operation. Looking a bit work worn now. Could do with up-dating with Lipo batteries which would make it even lighter. Seen here with lift motor running with skirt inflated. Steering interesting, with twin air rudders. Must get some videos of the action.

Fairey Huntsman & Swordsman by pmdevlin Fleet Admiral!   Posted: 4 months ago
I dont uses mixes, but do use exponential and rates (spektrum dx6i) with my twin screw brushless 4 foot fireboat. When at speed rates on, then it turns nicer, no roll, when going slow rates off so turns are sharper, if that makes sense. Mixing the throttles.. interesting not thought of that, but it will lose power/speed. We use mixing on planes for taxiing, particularly on water, but once airborne its off. My avatar has this as the cheapo motors just wont balance so it compensates for this on the water. With the boat its easier to control with rudder input. I like the thinking though!😁

Airboat - one rudder? by RNinMunich Fleet Admiral!   Posted: 4 months ago
From what I have seen of Airboats (including several in Florida many moons ago 🤔) two rudders are predominant. Offset Twin rudders seem to be smaller, not so long front to back and single rudders huge and seem to have been used only on very early versions of airboats. Must be a reason why they evolved to slimmer twin rudders. My guess is better response with less braking effect and consequent loss of speed in turns and / or less effect from cross-winds. Whatever, have fun with it, but watch out for the alligators 😲😉 Cheers Doug 😎 PS can highly recommend a visit to an alligator farm 😲😲
