Sub dive system.

Ho Peter, What gas do they use then? I was actually thinking more of Sparklets syphon soda blubs, er 'hic' 😮 If you want to go the gas route I suggest you look for some US model sub sites. They seem to favour gas tanks whereas in Europe the piston tank is more popular. I've been wondering for a few days why our antipodean colleagues haven't chipped in to this discussion! Reilly 4 for instance. He has at least one great sub model and has posted super videos of his underwater travels. BTW Pete, It doesn't end with just the ballast / dive tank system! If you want to keep an 'even keel' while travelling underwater the following are highly recommended. - Attitude controller (Pitch Controller), which constantly adjust dive planes to stop the boat pitching up and down, or even porpoising along the surface 😮 - Reverse detector. This actuates as soon as the motor reverses. It commands the pitch controller to reverse the action of the dive planes if you also want to be able to reverse while underwater. Otherwise the planes would have the opposite effect to that which is required and make the pitching worse instead of smoothing it out. Of course you can still sail and dive without these but depth control will be very difficult. You'll be constantly correcting and correcting the corrections 🤔 Just like with a dynamic diver. The Yo Yo effect! Cheers, Doug 😎

Pictures of American river boats...

Hi all, a friend of a friend, hoping to raise a few bob for a dog rescue centre has several pictures in black and white of the lovely old American steam river boats with some descriptive paperwork. Is anyone interested in a donation in exchange for these? Cheers, Martin

futaba radio and receivers

I don't have this system, so I can't speak from experience. But I see non-futaba receivers which are claimed to be compatible advertised. So I guess that you must be able to get such items. https://hobbyking.com/en_us/corona-r4fa-2-4ghz-fasst-compatible-receiver.html https://hobbyking.com/en_us/orangerx-gr400f-futaba-fasst-compatible-4ch-2-4ghz-ground-receiver.html https://hobbyking.com/en_us/frsky-tfr4-4ch-2-4ghz-surface-air-receiver-fasst-compatible.html If you buy from a model shop you should be able to try the receiver out first, of course. Here is a model shop's list of compatible receivers - https://www.rapidrcmodels.com/futaba-compatible-receivers-74-c.asp
