Hi, can anyone help. I have a RC SCALE Harz 2-6-2 ( Piko ) it does not respond to the TX very well, ie it runs very fast or slow, the loco has sound & lights. I have just stripped it down, it has one card which runs the motor, lights & sound, I would like to keep the lights & sound but use a 2.4 receiver plus a ECS. Can this be done. I have a photo of the loco card if this helps.

It looks like Newqida brand. It is 27 MHz so you would probably ditch the entire control board. It sounds obnoxious anyway. The battery is 7.2 volts so that may be an issue. Best to change the bluish LEDs to warmer ones too.

Someone experienced with 2.4GHz remote control setups will chime in soon I'm sure. :nod:

Running it at 8.4V (rather than 7.2V) may be part of the 'speed-control' problem, but they are notorious for 'all or nothing' running.

A link to a revue:


A fairly easy loco to convert to something better. - I have one somewhere.. I will have to dig it out.

Thanks for any help you can give. I have ran it with 7.2v & 8.4v with the same speed-control' problem

I'll dig mine out, and see if there is any chance of 'jump-starting' the Ni-Cad's. :rolleyes::giggle::giggle:

I found with mine the proportional control is only ever effective with very a fresh quality brand battery in the Tx. To be honest though I quite often used to set mine on auto (and with the sound off), turn the Tx off and just let it trundle round for a couple of hours with a couple of coaches while I got on with other stuff in the garden.

I changed out the stupid blue LED lights for warm-white.

This was it on a visit to a friend's line, happily hauling the pair of coaches which came with the set plus 3 repaints by the owner of the line.

That looks well, I am surprised that so many out there like this loco ,I thought you all would laugh at me for having a cheap loco like this. Thanks all.

It is quite amazing how many of us actually have them. - Though I must admit it only got ran a couple of times, and for all of one minute with the sound on! :eek: :giggle: :giggle:

I got mine soon after getting up 'close and personal' to a fellow G-Railer's collection of LGB Harz stock, so it got put away.

Amazingly.. The 7.2V NiCad pack seems to be taking a charge, and not getting overly hot, so it stands a chance of running. :rock: - Though probably not tonight?

Rather than laughing.. 'Thank You' - A reason to get my mojo back on this one. - Or is that a round-toit? :think:

Mine got converted to this using 2 x LGB 20231 Chassis and 2 Bodies. Radio by Fosworks and a My Loco Sound Unit. So much better now.

Offered the Sound Card, RC Reciever and Transmitter on this site some time ago. No takers hardly surprising. Chassis now a 2-6-0 as I used the rear pony truck in the above Conversion, Chassis kicking around waiting to do something or other with it.

Gutted mine and fitted a 2.4GHz Reciever (from Hobbyking), 10 AA 2300mAH NiMh batteries and a Pololu simple motor controller (my go to for simple motor control and are easily programmable from a PC via USB if need be). I usually remove all electrical boards etc and wire directly to motors and lights just find it easier and less confusing.

Controllers; Pololu Simple Motor Controllers Haven't used the G2 versions yet but probably will in the future.

It runs well, but as SWMBO has just discovered I now have 14 locos
(we are moving house and they were on the inventory), I am considering sacrificing 2 Stainz that are surplus to requirement (how many can you have?) to make a Garret type loco.

The chassis may be used for a scratch build as well, time will tell

Hm you sure about that Stainz Conversion Gap will then give you 13 Locomotives? Need to find 2 more to blend together to give you a more acceptable 12 Lokies.

I have one, but I haven't run it for ages. I also have the track powered LGB one, so this tends to get used more, whilst the NQD one sits in the shed.

Although I am MTS, I have the Playmo yellow diesel, and the Piko Track Cleaner which are battery, and part of my 'Maintenance' fleet if I just want a quick run without the hassle of connecting up track power....
