Wouter, thanks for the web sites. I wish I could read them. My daughter did not build in any angle into the rear tires. I do not remember any info about needing it in the information she got from the web. If you could measure it on yours, I am sure I could build it into the axles. I have come to take ownership of the land sailor as my daughter is sailing for the University of South Florida (Saint Pete). The wheels that are on the rear now have bearings, but the metal structure is to flimsy to handle the loads and now wooble. I considered the plastic wheels for the front but we thought that the spoked wheels would be stronger (wrong again). Anyway thanks for the help,
Carl
