hi everyone. has anyone ever built the grs quarry hunslet. the info on their web site is vague . is the chasis for it battery powered? is it actually 32mm. easy to build? even better if anyone has photos of theirs. thanks.

Hi! I've got the cabbed version to build when I get the time. The kit seems fairly straightforward but I suspect it will take a bit of work and upgrading of parts to get a really good result as some parts are a little crude. As far as fitting batteries and r/c are concerned you'll be on your own as the instructions don't cover this. The chassis is ready to run. There have been two build articles in Garden Rail and in the 16mm Association mag which are really useful and which demonstrate just how nice these kits can build up. All in all they are good value but not a throw together job I think. Good luck! Kubes

My version is the cabbed one too.

You have to specify the chassis you want 32mm or 45mm.

Mine has 10 1.2v NiMh AA cells in the saddle tank area and uses Deltang RC which will fit almost anywhere. Eariler I did manage to squeeze in a standard 2.4 ghz Rx and motor speed controller.

GRS do rtr chassis in 32mm as well as 45mm and coming from O gauge 7mm scale I have to say that the GRS 32mm chassis seems reasonably priced and looks OK. Worth a punt in my opinion!

The loco and wagons are 32 mm. I re-wheeled the Newquida wagons.

Looks smart. I have a cabbed version too, running on an LGB ToyTrain chassis. At present she's track -powered but she's on the to-do list to be converted to battery power. At present the saddle tank is full of lead. Does she pull well with batteries in the saddle tank - did you need to add extra weight?

Mine is also the cabbed version shown here before the body was fitted. I have found that to get effective haulage power I have to run the motor too fast for a realistic scale speed. The chassis comes with a 15:1 gearbox fitted and I have purchased a 30:1 gearbox to see if that makes a difference, although I have not yet fitted it.
I also fitted the batteries inside the saddle tank and the control gear, charging socket etc is between the frames under the cab. Quite a tight fit!
Generally speaking I think that it is a very worthwhile project and the kit from GRS does represent good value. (Usual disclaimer) It is definitely not a five minute glue together kit though, a lot of thought will be required to accommodate and fit your chosen control system, as the kit does not come supplied with anything.

The lower section of the boiler is full of lead and the 10 AA batteries,resting on top in the wider space, supplies the rest of the weight. Loco gross weight 1.5Kg. Pulls those two bogie flat wagons up a 1:40 incline with power to spare.

Thanks Graham
That's reassuring. Although mine weighs in at a hefty 2.25kg at present, I've found that converting to battery requires less weight for the equivalent adhesion. I think it's partly due to lowering friction by the removal of the skates and wheel pickups and partly because the wheels and rails no longer need to be shiny clean.

I've now moved her batteryisation further up the todo list. Somehow doesn't seem right to run a narrow gauge light railway without having at least one Hunslet in service ...  :thumbup:

Hoping to take mine to the Llechfan Garden Railway Gala on Saturday. Just giving it a workout on the rolling road at the moment so I can give the batteries a charge before the event. Don't want it to stall on me for lack of miliamps when I get there :lol:
