New to me TC6 off eBay. This is my second one. My son swiped mine! I like this aftermarket lipo holder. I think they were made for the TC5. So I mounted it on the TC6 chassis. It locates the lipo about 1/8" further away from the centerline than stock, but I don't think that will cause much problem. Set up the rear with 2 degrees and the front 1 degree.
