Thanks Ted!!!
Yeah, the 54mph speed (measured at 90% throttle) of the 4-8-4 is fine, I think your 25:1 on the Mike is correct (from memory). Not sure what the Lionel 4-8-2 is but I'll try to remember to check next time I work on it.
I'm pleased with all my battery-powered engines, just curious as to why a few were slower than what I was getting when using TMCC or DCS.
But there is a big difference between 12 volts and 9.6 volts. Maybe that's all it is that I'm seeing in these comparisons. That's 20% less voltage. Doesn't explain why the 4-8-4 was so slow (48mph) when using the 11.1 volt LiPo pack though.
I'm really surprised at how well my RailKing USRA 0-6-0 runs at slow speed, the gearing lets it crawl. Even the Weaver 4-6-0 I got from Ed Rappe is a great moving engine at low speed.
I have two RailKing 2-8-0, one has a 9.6v battery the other has an 11.1v. The oldest one (11.1) has a top speed of 70mph at 80% throttle and the newer one (9.6) has a top speed of only 55mph at 80% throttle. Both are faster than what I would run a 2-8-0, easy enough to back the throttle down.
Other than the 4-8-4 (now 12v NiMh), the 3 engines currently using the 11.1 LiPo pack are the faster group of engines.
