Odyssey Question

[rick486]

Got two questions really:

I've noticed that when the track voltage is around 14-15 volts, the odyssey speed control seems squirlly..i.e. the loco takes off wildly and derails....When the voltage is turned up to 18+, the speed control seems to stay level...Perhaps the TMCC electronics need a minimum voltage to operate properly?? Someone with expertise comment??

Secondly, with a less expensive TMCC equipped diesel (UP freight set), there was a way to set the crawl speed as well as the top speed via the eng ID# and the "SET" and "Boost" buttons respectively....With two of my more expensive, newer O-scale engines (PRR diesel and a Lionmaster UP Big Boy), there's nothing in the instructions for setting these...I've tried using the keystrokes from the cheap loco, but it doesn't do anything...It would be nice to be able to set top speed on all locos with small kids playing with them as I've had....

This one is new to me because I run full voltage all the time. I have Legacy cab 2 setup but my track comes up to full voltage at start up and never notice the issue. I do not have any Legacy engines just TMCC and they work really nice. I am going to test out this voltage issue and I will update you on what I find. I am wondering if you are losing the signal on the lower speed. Hum I will check that out.

The control set for speed I do not know on the legacy engines but dose work for my TMCC engines.

I have done some testing this morning and could not make my TMCC engines fail. I ran at 10volt and 6.5 volt and had no problems ran great.

Here is the engine.

Here it is at 10 volts

I believe it must be the number of feeder connection to the track causing the signal lost. This is just my thoughts and maybe someone else can chime in here with us.
