I was thinking that as long as we are modifying the motors in a manner to
perform better, I was looking at the possible places we could open the motor box
to allow ventilation for the motor. Perhaps we could cut a hole on the bottom
directly under the motor? My concern would be dust entering the box and gumming
up the grease, but directly under the motor I think the chances of this would be
less than holes on the top or in an end (mostly because the motor rests pretty
close to the bottom plate).
Another thing as far as DCC, if the decoder is overheating, could we mount the
decoder outside of the motor box to keep it cool? Maybe we could keep the RCX
cool with fans? If we go with "full Throttle" do we not use the RCS? And are we
running 9V or 12V on the track to power the DCC? I was reading someone's post
that said the decoder required 12V?
I will work on either replacing my gray wheel sets or modifying them. Another
concern I heard and observed in my visit to the show on Sunday was that a lot of
the engines had problems with the tunnel. With the larger engines, the fact
that the track is slightly banked may be causing the wheels to twist when the
body of the engines are not. I believe this is why my engine actually had to go
slower in the tunnel or else it would derail.
