Welcome to the club. First off settle on a weight category. Beetle and Feather are worlds apart in terms of the parts they use.

Second read through all the threads in your chosen weight category. There are dozens of starter threads that other people in your position have started. Read the build diaries section and find machines in a similar weight category.

Third, if you can then get along to a live event. There is nothing like seeing the machines in the flesh to understand the details involved and to speak to people in person.
