Builder's Notes:

1. SAM220 Frame: This is an interesting frame design, in that it departs from the current status que of cutting the frame from a solid piece of carbon fiber. Instead the SAM220 is actually 2 molded carbon fiber plates sandwiching a balsa wood core. This makes the design exceptionally light, and purportedly increases the "absorption" properties of the frame as well.

2. Betaflight F3 Flight Controller: Because this flight controller makes use of both sides of the board it requires more height on the stack than a single sided flight controller. That being said, it replaces any external PDB and OSD boards. While I am not totally sold on the vertical orientation of the power leads, the final result is a very clean design, easy to wire, amazingly simple OSD setup, and support for any/all features Betaflight has to offer.

3. TBS Bulletproof 25A BLHeli-S ESCs: If you plan to run DShot600, be sure to remove the cap. See this link for details.

4. Cobra Motors: Back in the day, Cobra motors were considered the "standard". That is until they started throwing magnets, after which they fell out of favor. I was happy to see Cobra bring some new designs to the table, and curious to see if they were contenders.
