Impressive. Both the build and your cranes lifting effort. Now try it with the Bissy!!!

6 volt Graupner Speed 400 motors for the Bismarck.

took a closer look at the datasheets of your motors: they're rated 18.000 rpm @ 6volts (mine are 16.400 rpm @ 7,2 volts) so you could run them with only 4 cells (4,8volts) and use a battery box for supplying your receiver using 5 cells will make her the fastest bismarck down under markus

Not necessarily - both the 6v & 7.2V Speed 400's are rated at 35W (according to an R/C flyer web site). The 6V draws a higher current to make up for the reduced voltage. The unloaded speed may be higher, but the loaded speed is likely to be similar. FWIW I don't know why Graupner quote the unloaded speed - it's not a useful figure Loaded speed at max efficiency (and produced power) would be more useful. Then if props showed a graph giving power against rpm, then you could match your prop to motor. If the prop gave a pitch figure, you could then work out your maximum speed (less the slip caused by the drag of the hull). it's all quite simple maths, if you have the right data..........

And in your calculations, remember to allow for water temperature and salinity! Wind and waves are extra.

LoL NM You forgot about whether anyone 1 was firing torpedos at you as well.

She be coming along fine Skyfire. Now chin up matie .................one plank per side at a time , and don't try to use too much pressure to get them to butt together. If they get too difficult, glue a plank that touches bow and stern, and let it lie along the frames the way it wants to go, glue it in position. Then fill the hole (gap I mean) in later by tapering planks. This may sound fiddly and long winded, but after a couple it becomes easier, and less stressful in many ways.......so to speak. The good thing about the Bluenose is that it's hull was painted (black I think..........'thinks again'...must check before opening my mouth and putting my foot in it ) Baz

The hull planks are the same thickness as bismarcks 2nd layer planking, so they bend very easily with hardly any force needed.
