Deltang Rx60 and Tx22 issues with power dropping

[Stewart Gethin]

Hi Guys,

Basically I have installed a deltang RX60 in my HGLW battery diesel. This loco used to run fine until I installed the rx60 in it.

My issue is the power seems to drop after about a yard of running on the track? Is it that the motor is asking for too much from the deltang unit?

What cells are you using? You need to ensure the RX has a high enough voltage to operate correctly.

I'm considering doing this with my HGLW loco at some point. Having read one of ge_rik's helpful postings on the Deltangs (http://riksrailway.blogspot.co.uk/2013/ ... ntrol.html) it seems that the 2.4V that NiMh AA batteries will provide won't be sufficient, so I was going to try to fit an 18650 cell in there. I think there's room (just about).

I've used 3 x AAA rechargable or 3 X AA rechargable (depending on the space available) in three locos I've converted this way with Deltang units and they work fine....

Hi Guys,

I've used 4 x AA Batteries in a trailing wagon to power the loco. (Before having the deltang fitted I used 2 x AA and it worked fine)

Have you got a way to measure voltage? It would be worth checking how much the voltage drops under load. What transmitter are you using? Make sure you are actually going to full throttle.

I am using a TX22 transmitter. When I open the throttle at all this happens.

I had this problem when you increased the throttle. The Deltangs have a LiPo protection setting on them which isn't needed for NiMh.

Programming info is here:

Then under Menu 7 look for LVC (Low Voltage Cut). It needs to be disabled.

Hi Stewart
You say you're using 4 x AA. Are they rechargeables? It sounds to me as if the batteries are not delivering enough power. One of the cells might be duff (I've had a similar problem myself) or there might be a fault on connections between the cells.

Does the LED flash five times when the loco fails? That's the signal for a brown-out (ie not enough power from the batteries)

I'll have to have a look at it in depth and get back to you. Thank you for your response.

If it's as simple as that Rik I'd love it! I'll have a look as thinking about it the batteries could've been sitting around for a while. But no they aren't rechargeable.

I'll let you know my verdict once I've sorted it.

Thanks everyone.
