Two years later and I am still contemplating if it would be possible to substitute an LGB, USA Trains or some other motor block into Percy. I was just out running Percy and found that the same old issues are still with us.
All of my LGB locos can run unattended, round and round without issue. Bachmann's Percy, on the other hand needs to be followed with my hand held remote. On up grades he slows too much. On downgrades he is a speed demon. LGB R3 turnouts can cause the occasional derailment. Uneven track is not a friend of Percy. The flanges of his drivers are too small I believe.
Has anyone substituted another manufacturers motor block into a Bachmann Percy ? If so, which one and were there any major issues ?
