LST 368

Not really an LST subject but I'm going to tell the story anyway. As Alice has built the beds in the Mobile Sausage Roll producing vehicle, I ordered the mattresses on line. They came just before 6pm today, Thursday. An hour later, I had a message from ebay saying that they were dropped off at 1.04 GMT on Friday 4th December. Time Travel by Yodel?. It's still Thursday as I write this. Cheers, a perplexed Nerys!

Wich motor

Hi Mark, That is undoubtedly a Hectoperm👍 Easily recognisable as the case extends right back to only a thin edge of the brush end cap. The Decaperms have a shorter body and different, wider, brush gear end cap with an earthing tag sticking out. Pics attached of both Hecto (pic 1) and Decaperm (pic 2) courtesy of Jotika😁. Also of my Decaperm (pic 3), now sitting on the shelf after long since being removed from my 1960s 28" 2kg Sea Scout, where it provided very sedate performance🤔. Pic also shows current fit of a Propdrive brushless. Much zippier😊 I assume that your Hecto is the 6V version, based on your preference for onboard power stated below, and the 6V 6.5(?)Ah SLA battery in the background of your photo. Therefore it's current draw at max efficiency ON load should be around 8A. These Marx motors are built for torque and pulling power not for high revs and speed! So I reckon your 6V Hecto should be fine to get your your 6kg freighter on the move. Freighters of that era were not known for speed, maybe 16 - 18kn. Accepted formula for max Scale Speed is the square root of scale x the max speed of the original in knots. You didn't tell us the scale but I'm assuming 1:100, or 1:96 if imperial units. For simplicity assume 1:100 and max original 18 kn. Thus Max scale speed = √1/100x18 = 0.1x18 = 1.8kn. Which equals a gentle stroll of 2.714mph😉 Or if you prefer 3.33kph, or roughly 1 metre per second😁 That hull can probably take a 6V 7-8Ah SLA without problems (better useful ballast than 'dead lead'😉) so I reckon you'll get well over an hour cruising (like I do with my 1.35m destroyer; 2 540s running on 2 6V 7Ah SLAs in series), or are you a 'pedal to the metal' kinda guy?😁 Hope this helps Mark. Looking forward to the Sea Trial report👍 Stay safe🤞 and don't run aground!☹️😭 Cheers, Doug 😎

The Duchess

Hi woodie, l A little diagram may help! please note a car fuse holder will do, The speed 600 will pull 85 Amperes when stalled (stops spinning due to weed or string) max efficacy is 12 A so a 20 Amp fuse would be a reasonable choice. Specification Nominal voltage 7.2 V Operating voltage range 3.6 … 8.4 V No-load rpm 18200 min–1 No-load current drain 2 A Current drain at max. efficiency 12 A Current drain when stalled 85 A Max. efficiency without gearbox 69 % Length of case, excl. shaft 57 mm Diameter 35.8 mm Free shaft length 8.7 mm Shaft diameter 3.17 mm Weight 195 g Hope this helps Regards Roy
