Thanks joe ..I found that making bushings drilled to the size of the tubing worked fairly well ..I had some 3mm threaded fittings so i tapped the the ends and soldered the bushings to the tubing ...I noticed that those european fellas building their vario machines are doing tubing as well...Did your machine come with that stuff or are you going to have to build that yourself.?
The mamoth tires are working great..Im thinking the other tires may add a bit more scale and a little more tracttion.
