Panther: Thanks for the info! I'm on my way to my local hobby shop now to see if they can help. They have a very large choice of just about any rc part made. I'm sure they'll be able to find what I need.
Erik: You have been a big help to me since I got into tanking, and seeing that all my tanks are Taigen, I'm sure you'll be hearing from me in the future. I may hold off on the jag gearing if you may have them soon. I'd prefer to get parts that are made by Taigen when they are available. Great customer support at Imex. So keep me posted about that shipment and I'll gladly wait. And LMK about those kv-1 gears also.
YHR: Thanks for that input. I may go with those for the k.t. If I can't get the results im looking for at the hobby shop. Like I said, I did it with my bulldog, and couldn't be happier. I added some weight to it and went with metal road wheels, and it rips through whatever I put it through. Also spent hours painting bed liner on the track pads. Man..... This whole tanking thing really takes you over doesn't it......
