RE: Tamiya Question
Ya know, the more I look at it, the more I think the Wecohe suspension system will fit. Looking close at the photo, it looks like the suspension arms are the same as Tamiya, and if so, the kit will probably fit. Pity I'm not nearer to you, as we could try it. Lemme talk to someone I know who has both the kit and the AT KV hull. He'll try it I'm sure.
Now, a question for you on the KV hull. Are the return rollers bolted to just the plastic hull, as I see triangular cutouts in the hull for what I think are the return roller bolts.
