Hi I have a 50amp speed controller (with blue anodised heat sink case) from China running a Torpedo brushed motor, but it only gives high power one way.(think about 20amps reverse). I found to get max power ahead my transmitter stick comes back, reverse at lower power is forward stick.
Good Morning Gents, .......and now for something completely different........ I enclose a picture of my model Thames Sailing Barge. Model Barges are very popular at clubs in the Essex and Kent area, because of the many historic barges in Maldon and the surrounding rivers. The members of Maldon Blackwater Model Boat Club have built several barges, but there are many other barge owning clubs in the Essex and Kent area who meet to run interclub Barge Matches. Most Model barges are built 40"-45" in length either 'stem head' or 'bowsprit' and usually they are fitted with a fin keel and a deep rudder, to give improved sailing abilities. Many are highly detailed models of specific barges; however the yellow barge is a 'generic' model with a 'Sirdar' hull built from balsa reinforced with grp. The model in build is based on a 'Veronica' grp hull and will be a bowsprit barge. These are the names of 'racing' barges, sadly broken up many years ago. I hope you find our particular passion interesting. Best Regards Frank Burgess
Thanks gentlemen, but you might as well know I am famous for fires and sinkings! Now you know why the club members were so interested in the Scudder trials.........................its like a Roman spectacle!
Thanks very much for your advice......running the model at my club at Maldon certainly generates a lot of interest.......there's nothing else like it, so there are lots of suggestions. One of our blokes is going to bring a 12v lipo Batt so we will see if the increased power gets it on the plane. Angling the motor helped a little, another possibility is to reduce the angle of the hull profile at the bows. Anyway...keep you posted. Maybe see you at Warwick ...the Maldon Coach should arrive about 11am on Saturday.
Hi I have refurbished this 'Scudder' hydroplane designed by Vic Smeed in the 50/60,s. I think it looks a bit like a marine Douglas Dakota! In place of a an OS MAX 3 15 glow diesel, I fitted a A2212/13T, 1000KV brushless motor and propeller and an HW H30A controller. It goes well but will not quite plane. It current uses a NiCad 7.2v. I have adjusted the angle of the prop/motor to push the nose up a bit, but will the motor/controller set up take a higher voltage so it will have more power? Hi Gents Update on the Scudder...I fitted an 11v Lipo, and relaunched. Loads of power; the hydro immediately went onto the plane and ran very fast....then the trouble started! The roof flew off, passed through the prop, and was chopped up...this in turn damaged the prop blades and possibly through vibration, the motor mount then broke up! Maldon never had so much entertainment!
This is my replica model of the Sirius Star designed by Max Coote of Ripmax, around 1954. I found the drawings on the internet, and built the model from scratch. The boat is 41" and I have fitted an electric motor taken from a childs ride on car, 50 amp Chinese controller, 50mm prop, and 12 volt 7 amp lead acid battery. It also has a Murco diesel fitted in the wheel house to give the boat a 50's appearance! Sea trials soon!
Hi Gents My new project. I have obtained the drawings of the Sirius Star a 41" motor cruiser designed by Max Coote of Ripmax. The boat originates from about 1954, I understand to carry the early radio gear. I eventually found the plan from the website 'Model Plans' who supplied very promptly and at modest cost. regards Frank
Thanks gents that's just the advice I need, and another good reason for joining this Model club............I can get on now.......just got to find a hull ..finish it ....send you gents a photo....its all go! many thanks again Regards Frank
Hi Gents I have 'come by' a brushless motor. its part codes are A2212/13T 1000KV I would like to use it in a fast light boat possibly with hydrofoils Can you tell me of a controller to run it......reverse is not absolutely nessessary and I would prefer to stick with NIMH batteries the info on controllers is very confusing can't work it out! Thanks Frank
Hi gents Thought you would like to see my latest Ebay acquisition. It very battered but I have lots of the bits! Its 31" long. It is fitted with an escapement type steering device. The main motor is a 'Pitman A Panther' motor made by Pitman Developments, in USA, and there is a mechanical speed controller. It also has Eveready dry batteries of American manufacture I believe this is an American kit, but because of the American equipment fitted may also have been built in America. Any guesses to its age, and has anyone seen a picture of the complete boat to guide my rebuild? The motor runs so I hope to retain that but fit modern controls. Any ideas appreciated. All the best Frank
Hi Have bought a part completed Precedent 46" Fairey Huntsman. It has the Torpedo 850 motor and was fitted with a MFA como belt drive, which I have removed to have direct drive. The prop Is a 2 blade 60mm dia, I wonder Is this will be too much? I like your Ideas on decking and windows etc...most helpful ,thankyou Does your Huntsman go well?
Well fellas, Sucess the boat performed pretty well, similar performance to the motor which burnt out, but without any drama. Checked the temperature of the motor occasionally, and It seemed warm but not excessive. The battery Is a 7amp lead acid (Motorbike type) and gave well over an hour running time. Unusual feature of the boat, Is that being big (46") the wash Is considerable. Thanks for your Ideas Best Regards frank
Well........more Sea Queen sagas. The wheel chair motor was no good at all. very low revs and negligable thrust. Fitted a replacement Johnson motor from a 14v battery drill, ......success!......reasonable pace semI planing for about 15 mins when the motor gave up In a cloud of smoke. I have been given a motor stamped Johnson 970 with a label 'Marlin MK2'. The motor has 1/4 shaft and runs at considerable revs on 12V and has been used In a model cabin cruiser on 14V. My prop Is a 3 bladed brass 50mm. I think this prop was too much for the original motor and caused the burnout. Would the bigger Johnson handle the 50mm prop or should I fit a smaller prop? Any Ideas? Best Regards frank
Motor Is now fitted ...its a 'Redmond' 12 V 10Watt.......not sure Its going to be right though...it has massive torque but low revs on 12V. I don't want the boat to be quick because my club majors on scale sailing models, and a 46" launch charging round the lake would not be popular! Any way nearly ready to go I'll let you know how It performs. Rgards Frank
Still finding my way round the site Pic of the Sea Queen with Jolie Brise In the background. Sea Queen will have the wheel chair motor, with Mtronks control. Joilie Brise Is having a new ballast keel cast to lowere C of G and Improve sail power.
Sea trials passed OK! The Graupner 600 drives a 38mm 2 bladed prop. Performance Is good not super fast. Interestingly this set up powered by a 3000mh nicad ran for nearly an hour. While at the Warwick show I asked for advice from one of the clubs exhibiting. My problem was that my electric models hesitated while running. The advice was that my 40mz and 27mz radio set ups were probably the cause and I should use 2.4MZ. This change has completely cured the problem. May be second nature to you chaps...but I did'nt know. Apparently the radio signals given off by the motor do not enter the 2.4 range.
Hi My model ASL now has Its electrics fitted, Graupner 600 motor Mtroniks 15amp controller and 3000 nicad battery. Sea trials Thursday...watch this space! Your model looks very good....there was a super ASL at the Warwick Show Regars frank
HI Yes It Is...I scratch built It using a GRP 'workboat' hull as a base. I used a simple drawing from the 'Jolie Brise' book blown up to size. I altered the bow, stern and the keel to match the drawing. The rig Is slightly undersize and simple the keel Is deeper, the deck layout Is very approximate taken from photos but simplified to make It more robust for sailing. It has a winch for sail control and the rudder Is controlled from the tiller via lines and blocks to a servo under the cabin top. As you probably know the boat was bought as a Le Havre Pilot boat by EG Martin who then Instigated the Fasnet Race, which Jolie Brise won 3 times. Thanks for recognising It.....best regards Frank
Thanks Lyle Great to hear from a colleague In OZ. It struck me, reading about the original boats with 3 Napier engines, God knows how much petrol at 35 knots, It was a bloody dangerous war for those blokes. Best Regards Frank
the scale Is half Inch to 1 foot..my hull Is 32" and the real boat was 63ft My turrets are just radio valves glass about 1" dia there Is a web site of a club for Air Sea Rescue launches with lot of pics Regards Frank
