you guys seem to have a very active shop which is very nice to see and love reading about. when you have a chance, please post your tips to making dnano racing successful. unfortunately, most other stores don't seem to show much interest in it, or they just don't spend much time outside their limited reach in the store in promoting it. i know it takes time, but it really does pay off when you see tracks like this one being very active vs. some that have not had any responses.
cudos to you my friend
