Range Safety Launch? by RNinMunich Fleet Admiral!   Posted: 8 days ago
I agree Donnie, I did just that (turning inwards seen from behind for moving ahead) on my twin screw single rudder destroyer. It made it much more responsive to the helm😉 Same with my long thin U26 Type 1A U-Boat. I am making the same changes to my Belfast cruiser, 4 screws, and the Graf Spee, twin screw. Both with single rudder. On my twin screw / twin rudder PTB they turn outwards. Cheers, Doug 😎

To be honest Doug I didn't read down all of the posts, that's why I put the ASR/MCS reference in, just as an aside I was a crew member on four RSLs in UK and abroad and accompanied 1659 to RAF Abingdon for the 50th Anniversary of The RAF Airshow in 1968 which is quite sobering when I realise how long ago that was, the launch was 11 years old then, and it is still working in Holland today.

Mornin John, pdf works fine for me! Left click on the icon so that the larger one appears in the 'Media Gallery' window. Then left click on [Download] in the top left corner of the window. Windows then asks you if you want to Open or Save the file. If you're using a phone - DON'T!! Cheers, Doug😎

I use silicone grease. Looks like Vaseline. Works great.🤓👍 Can't open the PDF Doug. I have Adobe ????👍

New info I've never seen before. I wonder where robbob got that drawing! The 2 photos are fascinating as they show the angle metal screwed top the corners and chines all round. I can understand someone getting so into the details, but I have to stop myself. My natural inclination is to put everything in, but I want the model to look like it might have been given to me for my 11th Christmas, 55 years ago, so must stop short at what might have been a conscientious building effort by a proud Dad. I would, if I were a much younger chap and free to indulge, buy one of the 46" kits and do a real "number" on it, detail-wise, but I ain't. So a half decent finish is what I aim for. My main concern is finding the damned Taycol motor I rebuilt for it! I went to the drawer of early motors and it wasn't there! Panic!! Thanks for these new items of reference, robbob. Martin

Hi George, if they look the same as mine then they are geared! Good for a tug. The gear box is the bulge at the business end 😉 Might pay to apply a little Teflon grease to the gears!? BTW: The P94 has a rudder mixer built in to assist with turning! It might be that you are chasing a ghost😲 If the rudder trim is a bit off centre it might affect the motor speeds? Effect depends a bit on the Mode you selected on the P94. Especially in Mode 3! Nevertheless; the above tips are good maintenance routines. Have fun, cheers, Doug 😎

Doug thanks again for all your help not sure if my motors are geared or not but they look exactly the same as yours. My tug is 1/24th scale I think lol Cheers George

Hi George, Good setup for a tug, mighty meaty👍 With or without gearing? I had one in my Sea Scout but the performance was 'sedate'🤔 Pic shows the old and the new ! For a tug they should be ideal though, lots of pull😊 How big / heavy is your tug? I also have the P94 dual ESC from action. Was going to put it in my Southampton tug but now think it would be more useful in my 53" destroyer because of the rudder mixer! Hope some of the tips solve your snag, fingers crossed😉 Cheers Doug 😎

Thanks Doug for your response I will try everything you mentioned I have decaperm motors and dual esc from action electronics. Cheers George

Hi George, Had this snag with my Graupner Graf Spee as well. In my case the stbd prop tube was misaligned 😲 Major surgery 😡 First off; it's unlikely that the motors are perfectly matched, but if the difference is that noticeable I would suspect the cause lies in propshaft resistance and / or dry motor bearings! I would disconnect the prop shafts, oil the motor bearings and run them in a bit off load for a few a minutes. See if you notice a difference there at low speeds. Also; remove both shafts; clean and oil. Clean the tube end bearings with a pipe cleaner and some light machine oil. Squirt some Teflon grease into the tube from the prop end. I use a small plastic syringe for that. Before reassembly check as far as possible that neither shaft or tube is bent at all🤔 If all seems straight reassemble and run the motors at medium speed a minute or two then slowly and see if you can still detect a difference. Reduce the throttle gradually until the motors stop. If one stops significantly before the other that suggests extra friction in that drive train; misalignment somewhere! Thrust washers too tight? BTW: which motors? One ESC or two? Hope this helps! Cheers, Doug 😎

Hoping I might find out some advice I have a smit zweden and one motor seems to be running faster then the other anyone got any ideas?

Air screw driven hydro by boaty Captain   Posted: 10 days ago
Thanks Westquay. I like your comments about air boats not being used much anyway. This is very true. Even if the boat was powered by an electric motor there would always be some miserable sod who would complain about the rotating airscrew. Boaty😁😎👍

Warning by onetenor Fleet Admiral!   Posted: 10 days ago
Funny I usually mention the apron trick and a doggy on a lead????? That's a magnet on a string. I use speaker magnet with the isert. I trap the string in the hole with the insert. Dragged around the floor will pick up any ferrous stuff. Another is a telescopic rod with a magnet incorporating a light for nooks and crannies Where springs or spring loaded stuff fly to. The Apron you can buy or make with eyelets on the hem hooked over little hooks like those used on curtain wire or tiny cup hooks.Screwed under edge of bench. A round Water of Ayr stone (cylinder) is very handy too. Give the stones a clean now and then in detergent rubbed in by hand or meths/paraffin mix but use wet. Good luck.👍

One crew member modified to have separate arms to keep the caster happy,so that'll go back for moulding tomorrow. I reckon crews could be ready in a fortnight. Cheers, Martin

Don't do it! Use a river or a public lake. We HAVE to middle finger the arseoles who would have us using electrics as a matter of course. Rivers and canals can be used with ease as the real thing is already dirtying up the water, which, of course, the wild life are well used to. As an air boat would never be used that much anyway, keep it for when you travel to a river. Keep the electrickery for the Jobswuffs. AM 15 is a great little motor. I used to have one. Alweays started easily. Trouble is these days the fuel ain't exactly cheap, but then, neither is a brushless motor, Li-Pos, special charger, watt meter, battery condition meter, special wires and connectors, and of course special ESC which will almost certainly burn out like they all seem to eventually. Failing that put it on the shelf and await interested questions! Martin
