I have finally returned to work on this project after taking a long break! I just completed my training with American Airlines on the E-190, and I am now back to a semi normal work schedule. Actually, I will be on reserve for the next month or two, so I will have even more time to do some modeling if they don't call me to fly!
This is my second prototype of the model, and I really enjoy experimenting with improvements to make my design better. On this model I used a more powerful 4mm motor out of a micro R/C drone. I also used M0.2 mod gears from shop.kkpmo.com instead of the M0.15 gears I used on my Pennsylvania 4-6-2. The M0.2 gears have larger teeth, giving a little more bite on the gear mesh. However, this lowered the gear ratio a bit. I used 12 teeth M0.2 gears to drive each steam wheel, and 13 teeth for all other gears. This gave me the same spacing as the M0.15 gears, so I can use the connecting rods from TGauge.com.
The model is running beautifully, and has lots more power than my PA 4-6-2!
