Building Fool-Flying Noob
This is shaping up. I had very good success building a dual sweep with with my Heaven's Spade Carrier. Take a look at that if you want another idea. They are right about having a separate BEC and you need to make JST split of the main lead from the battery, and depending on your comfort soldering, you many need to buying a setup. While cheap, This can add some un-needed weight. I bought a few as my models get bigger, the weight is less an issue, and the motor count increases.
