Improving running of 23mm power unit

Postby dkightley » Tue May 31, 2016 11:11 pm

I've just bought a couple of 23mm power units that I intend running together as a pair and I've had to add a weight to each of the units to make sure they run correctly....as shown here:

There's just enough room to fit half of one of the self-adhesive weights that come with the adjustable chassis, etc. Without it, the non-powered end is too light and has the tendency to jump off the rail.

I've also noticed that the unit runs more reliably in rear wheel drive configuration, ie non-powered bogie to the front....to the left in the above photo. Running the other way, the unit tends to occasionally derail the non-powered end bogie.

Hi Doug
Thanks for that information as i had issues when running my full 9 car HST as the non motorized coaches did not run and tend to trip on the passing turnouts.

I have then placed the weights in from my Adjustable kits supplied within and they seem to do the trick.

Regards
Gr :lol: aham
