CPO-135-Tricopter-Body-pdfCPO-135-Tricopter-Booms-pdf CPO-135-Tricopter-Body-dwgCPO-135-Tricopter-Body-dxf Alright…let’s get to the good stuff! Here is all the content related to my CPO 135 Tricopter build. Most recent stuff is up top. If you want to go through the entire process in a systematic fashion, start at the bottom and work your way up. I start out with my design concept, and go into some tricopter design theory…then start the build. There are now two versions of the CPO 135 Tricopter. One is “The Original” which is a large FPV focused machine. Because of it’s size, it is very smooth and stable…perfect for FPV. Don’t worry, it’s lots of fun, and can be flown hard. The latest version, however, is more of the race car. It’s called the “G10 Shorty”. I am using laser cut G10 body panels on this build, but the original wood is just fine. The booms are 150mm shorter than what I call for in the original build plans. I am also cranking up the stick scaling and other awesomeness in the KK2.1 to push it to its full potential. This is a great version for those that want to play. I left the camera tray off for now, but the same method can be used to put a camera on it as used in the original. Enjoy!
