I was running a QAV-R 180 clone (4") for almost 1.5 years, which I really came to enjoy flying. It eventually became a basher that I used for warming up, light racing, and light acro. In early spring, I managed to break a motor in half on a gate, so I rebuilt it with some new components, and also added a RunCam Split for HD recording. Fast forward to late August of 2017. I had another bad crash with some smoke coming off carbon fiber (due to antenna connection short), and the motor screws really dug into the frame. So I decided to start a new build. Good 4" frames seem to be hard to come by, and I don't want another X frame. I've always appreciated Shendrones design, and fly a 3" Shrieker that I really enjoy so I would like to give the Tweaker a try.

My goals for the new build: no X frame (have two others already), re-use my Runcam Split, and have something fun to fly that can keep up with 5" on the race course. Budget is a concern, especially with FPV Fest (in Willard, OH) coming up in a few weeks. Fortunately, I have several parts laying around. After doing inventory, the only thing I really need to purchase are the 2205 motors, though I'm also going to try the Omnibus Betaflight F4 over re-using my current one. I normally purchase "name brand" components after being burned by clone parts in the past. However, after seeing a lot of positive reviews on the Racerstar motors and the Omnibus FC, I would like to give them a try.

Update: after completing the build, I am really amazed how well it flies stock settings! I did a lot of soft mounting, including the PDB, the Runcam Split, and the motors. I designed the soft mounts for the PDB and Runcam Split. All up weight (without battery) is 300g, which I think is pretty decent for a 4" especially with a 5mm thick frame. I can fly 850's or 1300 lipos on this build no problem, getting around 3 minutes. After doing a maiden LOS flight, the motors were cool to the touch.
