Here are my notes from my first builds, hope it helps you out some. I've built 4 flippers and these are the notes I've accumulated during the process. If I can help feel free to shoot me an email
larevo@gmail.com I can send you some pics of what I've created as well. I've learned most of what I've done on this forum and online. Some really good stuff, just have to find it is all. Just want to pay it forward if I can.
Sorry if the notes are hard to make sense of, I plan on putting all this down in more a tutorial at some point but hopefully it can help answer some questions you may have to get started.
