Hi Jeff,
I just got two sets of low speed motors for my non S&S Tiger and Pershing to help with this problem. Once I get some help on working with these electronic things, I'll start doing my own modifications. In my museum, I run them all slow and try to make them look like the real ones. Nothing I can do about turret traverse speed....the Tiger was very slow, even with power traverse. The driver and TC had to coordinate and place the main gun in pretty much the right direction for the gunner to gain speed in engagement. I did the same in Korea. On the models, they are generally too fast to be realistic. Maybe I'm too museum or authenticity minded, but having worked with 1;1 scale and have dealth with the speeds, it's sometimes hard to replicate it with a HL tank. Just got my Super Pershing about 95% done and now have to find a way to make it sit a bit lower in front to replicate the weight from the long gun and added armor. I guarentee it will move slow.
