It adjusts when the ignition fires as it works off a Hall effect sensor but is a wasted spark setup. That in effect allows it to rev at high rpm or low and lumpy depending if you advance or retard it.

The blower is used when the locomotive is at a standstill as it draws the fire. When the locomotive is running it isn’t required as the exhaust gases passing up through the chimney is enough to draw the fire.

Thank you so much ! that is really helpful, this confused me for a long time ! @@neilbottle6662

Thank you so much ! This confused me for a long time ! Really appreciate it !@@neilbottle6662

Hi, I am sorry to bother you again, I have two more questions about the train operation , 1. As the train starts to run , should I leave the water bypass valve open or closed ? 2. How to empty the water left in the boiler after finishing each running ? Thank you Best regards @@neilbottle6662

​ @zhengyangwang9713 That's ok, we all have to start somewhere so I don't mind the questions. The water bypass generally depends on the amount of water in the sight gauge glass. If it's full up to the top nut open the bypass, if it's 1/2 or 3/4 you can leave it closed for a few laps so it feeds water in but you have to try and balance the water and steam pressure because when cold water goes in it lowers the pressure. I find when running for an hour I will only open the bypass a few times for a couple of laps or when it starts priming which is when water starts getting ejected out the chimney. When you've finished steaming, at the bottom of the sight gauge glass there is a copper pipe and a handle, all you have to do is turn the handle and it will eject the water and steam from the boiler, to avoid it going in the cab I usually put a small piece of silicone tubing (like that used for nitro engines) on the pipe and then open it so it drains away from the engine but be careful as it's hot and could scorch you easily.

Haha thanks, but she’s been gone a long time, 520bhp RS3 now 😂

@@neilbottle6662 RS3 is a beaut, is it tuned by MRC?

@@11dm No it's tuned by APR, they've got a video of it being mapped

@@neilbottle6662 you got a link?

@@11dm Doesn’t really show the purple that well, kzbin.info/www/bejne/aomroWyaj7SdarM This one’s better kzbin.info/www/bejne/Z3eQoaOCm8qgjM0

There is 1 video of it running on track in my profile. I hope to do some more when the track at Ruddington is open again as I have several more big wagons to test. It’s lovely to steam and can run for an hour, just have to top the water up in the tender.

No mate, moved onto an RS3. Yeah I know the two lads, ones got a white K1, the other is black.

Neil Bottle haha small world ,only came across your vid through wanting to get one myself soon. I’ve seen the white one a few times ,sounds epic on full throttle ,I was behind it a little while back in the wet along the straight by Morrisons and the noise as it was trying to traction was mad. No doubt I’ve probs seen your rs3 then if you still live in the area

@@DG-ge2bo You can’t miss it, it’s purple! Yeah he’s got a few bits on it, forged engine making over 400bhp but they struggle to put it down. They’re nice cars tbf if you get one with the additional options, mine had a lot of add on’s, sat nav, sunroof, xenons from factory and was pretty clean for how old it is.

Neil Bottle ah nice ,now I know I’ll keep an eye out! Yeah not surprised from the noise it was making. Yeah definitely gonna pick carefully ,I was keen on the cupra 290/300’s ..especially the estates being 4 wheel drive but that rawness of the older models is what’s drawing me in

There are a lot of variables, this one can pull around 3-4 people as it’s fairly small but our City of Truro in the same scale can pull 10+ quite easily with the ride on trucks, it can still pull more.

How strong are they? The little engine in this video answers it: kzbin.info/www/bejne/mnzQfXxjqN-Jick

George Kruczko VIS high pressure fuel pump, welly intercooler, RS4 fuel valve, runner flap delete, turbo back miltek exhaust, uprated clutch and brakes, anti lift kit, lowered on springs and a VW racing intake. That’s all I can think of at the moment

Jack Boddey The plans were in Model Engine Builders number 10&11. I believe you can order them online and the magazine will e-mail the issue over and you can print them from the issue.

Just need dual carbs

That’s at Shackerstone Railway. Some of the gauge 1 people were supporting as there were some big engines visiting. Only a temporary track but being indoors helped

Alex Dinu peaks at 25psi, not sure at redline cause I’m usually more focused on staying on the road and shifting gear

gardeningklp I use a couple of drops of two stroke oil mixed with Coleman fuel that’s used in camping stoves. It doesn’t smell quite as bad as petrol and seems to run fine on it.

Chris C No it’s built by drawings from Charles Kennion but the cab was added as an extra by my dad when he built it as an apprentice.

@@neilbottle6662 Neil, would you still have any drawings of the cab as it was built by your father? I am more and more keen to have this same look every time I watch the video. Cheers.

Chris C it’s certainly different! I much prefer it compared to the open cab. He’s away at the moment but I’ll ask him when he gets back. If not I’m sure I could take some pictures and e-mail them to you.

My dad didn’t draw up any plans for the cab, he just kind of made it up as he went along. It’s a fairly simple design really.

@@neilbottle6662 Perhaps a few flat-on photos with a ruler included for scale? I don'tmean to be a bother.

The engine was purchased from The Steam Workshop as they had purchased it from an estate, although there wasn’t much history with it. It will be getting torn down and repainted soon to add some finer detailing to it.
