I would like USA better if they got rid of that stupid floppy truck on their 6 axle locomotives.

I agree that USA has finer detail than some Aristo equipment on the other hand, USA's detail is more like to be broken.

I find the USA chassis design easer to install batteries.


I think the biggest issue with the USA motor draw is just the starting current. My SD-45 draws as much starting current with the wheels up in the air as my GP-9 does when running on the track.

I have not run my SD-45 long enough to find out if it's battery lasts longer than the GP-9.

I understand the simplicity of PNP but the 3 amp limit is a negative for the QSI controller. At 14.4 volts, the AirWire receiver is rated at 7.5 amps. On a USA engine, 14.4 is just fine. It's just OK on the Aristo engines.
