1. Athearn blue box rectangular gold stock with brass fly wheels #1
2. Helix Humper Can motor #1
3. P2K stock open frame motor and brass fly wheels #1
4. Mashima 1824 can motor with brass fly wheels #2
This engine is shown in the following figure:
This discussion will focus on the performance measurements of the unit. The basic test requirements are as follows:
1.) Powered with DC voltage with no pulse wave modulation
2.) Running on a level surface, measured and adjusted as required weekly.
3.) The same 8-foot segment of track is used for all the basic tests.
4.) the track is cleaned before each test.
5.) the unit is run without external load for all but the max draw bar force tests.
6.) Each track running data point is the average of three measurements.
These discussions can be down loaded for $0.50 here:
