The stream passes through the lubricator and drags it along to the cylinders to oil them

The steam oil (grade 460 only for model locos, nothing else) is specifically formulated for use in lubricators. As per the other reply, instead of breaking down, it’s designed to be carried with the steam to oil the valves and pistons that can’t be reached externally with the normal oil

Send her back to the maker. If u want to save some labor n shipping costs, u can remove the boiler urself off the chassis n body. Or maybe it's nut (not) the boiler dat's leaking. Maybe condensate from the cold cylinders leaked into the smoke box? Chk it out.

I have to say I do not have a Caradoc, but I do have a Mortimer (similar 0-4-0 layout) and that tank takes about 30 seconds to fill and indeed lasts about 20-25 minutes. The question has to be asked, are you sure it is full when you think it is? Does the gas spray out as it does on my video? I cannot see any other possible reason as to why it would only last 5 minutes when full.

Thank you for your reply. I probably don't fill it for 30 seconds (seems longer than you think), i'll give it another try and see. Many thanks.

Also you can try once it’s full try pressing down but not a strongly and that tends to get at least 5 more minutes on my Talgarth which is quite similar to the caradoc and ragleth.

@@AceEngineeringWorks Or, it can b a bad input vale can also b the cause. Unscrew it (need a forked wrench u may make out of a flat scrw drvr) n check it out, or just replace it. It's known as Ranson valve used for a butane cigarette lighter. RndHse shld have a spare... Also, if the tank's temperature is too cold, the gas won't go in. May try wrapping the tank w a warm soaked cloth?

DRIFT3RS consider the roundhouse basic series. They are incredibly simple, but when upgraded they are wonderful. They are also good for beginners, if you are one.

Whist I agree with the points raised about not checking the r/c, generally with 2.4 ghz radio systems they either work or don't. That said once you get to know your engine you will know by a quick glance whether the regulator is open or shut and sat in gear or not. Therefore the engine will simply not take off. With regard to battery level, I listen to the servos when operating. If they don't sound right, then its time to change the battery. The generous use of oil is something I often do. Yes it may create a larger surface area for collecting dirt, meanwhile it also flushes it out at the same time. A mere dab of oil will also in turn gather dirt particles that do not get flushed out if not generously applied. This is my theory and I'm sticking to it. I have engines that are 20+ years old that I have owned from new, ran regularly and not had to replace motion parts on yet. For me this system works. For lighting the burner below the smoke box. You cannot simply generalize where you light an engine. Most accucraft you open the smoke box and light inside. Be aware of what engine you have in front of you and adapt your technique to what it needs, (eg gas tanks are always filled differently, you wouldn't try and fill an accucraft ngg16 gas tank in the cab? You wouldn't light a Roundhouse Millie at the chimney?). With this particular engine lighting under the front buffer beam is easier, quicker and safer. The gas is heavier than air so it takes a while to get to the top of the chimney. Any delay in ignition will see the loco standing in an invisible puddle of gas, which will then go "pop" with all manner of interesting results when a source of ignition arrives. Lighting under the buffer beam puts the flame where the gas IS, not where it might be. May I also add that manufacturers/builders do not put perishable items directly below the smokebox alowing paint, radio or general damage to occur. We have all had smoke box fires that have not popped back properly so the area below the smoke box is in the direct firing line from this also. As for the locos general condition? She was 15 years old when this video was made so please excuse a little scuffing from the occasional derail. Surely you must have had one of those once in a while? It shows she has been used....

What's funnel? Or is it tunnel out in the track ahead? If this Lady Anne is truly a lady, then she must have her petticoat as a funnel under her boiler?
