Looking for some advice in getting more juice into a couple of my Taigen tanks. My Jagdpanther is fairly quick, and I feel a 4:1 gear box wouldn't slow it down to much, but I can't find 1 anywhere. I also have a King Tiger that has decent power, but they both struggle with spins and turns in the shortest of grass. It's kind of disappointing. I have modded a couple of my other tanks with help from this forum, and I was very happy with how they turned out. So do I go with bigger motors, if so, how big? Do I change tooth count on the gear, if so, how much? I'm stumped, and any advice from some veteran tankers would be greatly appreciated from this newbie. Thanks in advance.
