Focsle by Gdaynorm Commander   Posted: 3 days ago
Actually you sent me the bow shot some time back. What I am missing is the layout of anchor winches and anchor chain runs. I guess they will be similar to Nelson. Pity Greenwich has got SO expensive!

Hi Norm, maybe this GA dwg and bow shots will help a little? Cheers Doug 😎

H.M.S. BRAVE BORDERER by RHBaker Fleet Admiral!   Posted: 3 days ago
Once the rudder, propeller and shafts were installed, the position of the motors could be established. A light aluminium bracket to hold all three was fabricated and bonded to the hull. Due to the high speed capability of the brushless motors, particular attention was paid to alignment. Also kept to the shortest prop. shafts that could be fitted to avoid whipping. Although the motor type might change, whatever is best will require a sound electrical installation as the current requirements for each brushless motor could reach 50 Amps. Wired each motor and ESC separately with its own dedicated fuse to give the maximum system protection. There is an extra fuse section allocated for auxiliary circuits, such as a cooling water pump and lights. Will try the original planned layout of 3 x 2835 motors with 30mm propellers and a 2S Li-Po battery first. Am hoping the reduced voltage will also make these motors more tractable. For the test program the three ESCs will be each controlled from an individual Rx channel. Once the final layout is determined, a more sophisticated and flexible control system can be installed. To minimize ballast, particularly around the stern, the battery will be housed as far into the bow as possible. After the test runs the final battery type, size and location can be established. To assess performance, hope to try both 2 and 3S Li-Po batteries. Planning to reduce heat build up by fitting cooling water jackets to the motors, these are easiest to instal at this stage so the wiring or mounts are not disturbed in the future. Have not decided the layout for the water circuit yet, but this easily can be added later. All that is needed now is the ice to melt off our local lakes so tests can commence.

Choose a brushless motor by CB90 Commander   Posted: 6 days ago
1. Added strakes to bow used a rectangle section of styrene as more flexible. 2. Brought a motor mount (cooled) but may also add a jacket. 3. Painted cabin will need to redo as paint cover was poor. 4. Looking to find the best brushless motor for the job, remembering these boat race on 7.4v 3300mah batteries fo 5-6 mins. That gives a ruff consumption of 33 Amps which means the motor need to be able to handle about 250Watts. I have pick out 4 to test 1. 2850 2650 kv, 800W, max 19v, max 52A. 2. 2860 4050 kv, 1300W,max 12v, max 108A. 3. 3650 3930 kv, 800W, max 13v, max 60A. 4. 2845 3100 kv, 800W, max 17v, max 47A. On paper it should be between 1. and 3., 3 being the most suited ???. So on paper motor 3. running 7.4v will give 450 watts max at (60A max current at 13v) so 7.4v should have a max a round 30A (unless stalled). giving 222W 244.2 watts target at 7.4v = 33A max for 6 mins on a 3.3ah battery if battery function is good. 33A drain will depend on the propeller size 32mm- 45mm ! A safety margin may be 30A when moving and 33A in bath. 7.4v x 3930kv = 29,082 rpm perfect for hydro, not for sub drive.

Hi John, Thanks 👍 yep apart from constant battle with blood pressure I'm battling along! Sorry to hear about the leg, less port? (And I'm writing that with a glass of tawny at my elbow 😲) All the best Doug 😎

Help Needed new Builder Billings St Canute by Richard7 Chief Petty Officer   Posted: 12 days ago
Hi everyone, l checked the planking balsa in the kit and they are all the same length, so when fitting l assume that you should start from the bow end and the next from the stern end and vice versa. Then fill the shorter lengths use a full plank strip and cut small lengths to fill the end gaps? Between us l cannot see what the logic is behind Billing Boats doing this? Both my previous billing boat kits came with planking longer than needed. All very odd. I will ensure that l strengthen the keel as suggested, thanks to all for your help. Frodo l look forward to seeing some photos of your planking once you’ve started. Cheers Richard.

Help Needed new Builder Billings St Canute by Richard7 Chief Petty Officer   Posted: 13 days ago
Yikes Frodo, I have just measured my plank lengths and indeed they are shorter than the hull approx. 90-100cm!! Considering two kits are identical this must be the intention of billing boats. Has anyone got and advice on this? I was thinking that it might be best to split the plank in half, glue the bow and stern ends first, then glue a plank section in the middle area? "We could do with some help here chaps". Another thing Frodo, do not try and fit the M500 motor I have!! (please see photos), stick with the M400 its smaller. As you can see in the photos my battery will not fit....GULP. Does anyone know if there is a smaller battery out there? The one I have is a 4405385 (Cornwall model boats P/N) 7.2V 3300 H. One other thing Frodo "DO NOT" fit the metal rudder post & item 16, if you do you will not get your inner prop shaft into the tube. The only way to do this would be to remove the motor. Probably best to leave the rudder & item 16 until you have fitted the motor & battery. Also I am finding the space in the hull is very limited for radio control, choose your equipment wisely. I am now thinking I must ditch the M500 motor for the M400 and then look at alternative battery size. After building the Boulogne-Etaples this St Canute kit is extremely challenging. Anyone out there with some suggestions would be a great help....kind of sinking here a bit (a few photos attached) Frodo if you have any further questions please let us know. Cheers Richard.

Grimmershorn II by CB90 Commander   Posted: 20 days ago
[Score: 5/10] 40"/5000g Grimmershorn II Capable of 7mph and a runtime of 60mins Single Propellor (3 Blade 70mm) Direct Drive to a 950 (3 Blade) Powered by Lead Acid (12v) 12Amp/h Batteries Controlled Through 15A 24v (5Amps) ESC - Comments: The Motor vessel 'Grimmershorn' was built in 1956/57 by Hansa Stahlund Schiffbau GmbH at Koln-Deutz for the Waterways and Shipping Administration at Cuxhaven.Her Daimler-Benz four stroke diesel engine had an output of 500hp. permitting a speed of 11.5 knots. The model hull and deck are vacuum formed ABS, timber work of precision cut ply, 2 full size plan sheets and a construction manual along with a fittings pack complete this kit. Technical Data Scale: 1:20 Length: 1038mm Beam 305mm The Grimmershorn was the second major kit I purchased from a model shop on the outskirts of Harlow in Essex back in the 1980s. The Krik kit is still produced and sold today. My build was a slow and lost enthusiasm so after completing the hull, deck, motor and bow thruster installation I gave the boat to my father in-law who completed the superstructure and sailed the boat for a while, eventually the boat was given back to me when the father in-law moved house. I then repaired the rudder, added a moving radar, a adjustable water cannon and pump also various extra fittings such as a detailed life raft and crane, buoys and captain figure. thus renamed the boat as Grimmershorn II a Search and rescue fire boat.

Bismarck paint scheme (for Rookysailor ;-) by Rookysailor Lieutenant   Posted: 28 days ago
Fantastic photo's Doug, never seen these before. The one without the camo but with the bow & stern waves is an option in the trumpeter paint options, which I like best. Very quiet show at Heywood but got a decaperm 6v for £10 and a Marcle card model of Tirpitz @ 1/200 for ....£10, a bargain.👍 many thanks, Peter

Bismarck paint scheme (for Rookysailor ;-) by RNinMunich Fleet Admiral!   Posted: 29 days ago
Hi Peter, have found some more pics that indicate a simple black and white camo pattern applied March 1941, including some rare colour photos😊 Pics 1 & 2; painting at Kiel. Pic 3; canal near Kiel March 1941, Pic 4; Oslo 1941 before heading into the Atlantic and Denmark Straight, Pic 5; down at the bow after hits from Prince of Wales, Pic 6; as built Summer 1940 before commissioning. Pic 7; alleged paint scheme for Unternehmen Rheinübung, May 1941. Stripes are gone but false bow wave and stern are still there. Can't find official archive corroboration of this so like I said 'You pays yer money and yer takes ya choice'. Think I'll do mine this way and leave the stripes on as in the photo near Oslo. Happy painting, cheers Doug 😎

Bollard Hieght! by figtree7nts Fleet Admiral!   Posted: 1 month ago
The bollard height on the Brooklyn. Is off by about 1/8" towards the bow. And a little over 1/8" towards the stern! If you use the recommended height. Given the bollards don't have enough to bite on. So I compensated by adding 1/8" to the bollards! Now by adding the thickness the bollards needed. The bollards are in their right height.... I've seen this inaccuracies on prier Brooklyn's built! If you take a look at the picture of the Brooklyn. You can see that person followed the Dumas instructions. Which gives the bollards incorrect height! My bollards will be at the correct height required! 👍
