I have a pre-built racer called the Vortex. For hobbies like this with lots of variables, unique setups, and many technical aspects it just seems like a Moodle course on getting started would be a great resource for beginners. For people with the pre-built racers with standard equipment it would be easy enough to put a course together. I might give it a go and see what I can make.
For the past 9 months I have been loving flying Quadcopters. It is such an amazing experience flying like a bird with the first-person-view goggles and the freedom to explore parks/open spaces.
