Hi. I'm extremely new to forum posting and quad building, but I started a build with the help of someone who had done it before. I am using the Spektrum F400 Raceflight Flight Controller. I have attached the receiver, which is also Spektrum, and have bounded it to the controller. In Raceflight I get feedback from the controller so I know the receiver is bound correctly. My issue is that the ECSs will not react to the controller, or the Raceflight motor tab. Even when I try to arm them nothing happens. I was wondering if this could possibly be because the F400 flight controller is not compatible with the ESCs. The list provided by shows the Lumenier 35A BLHeli_S to be compatible. The ECSs I am trying to use are Lumenier 30A BLHeli. My worry is that the 30A and lack of _S are making the difference here. If this is not the issue, let me know and I will post a picture of the wiring and full parts list so someone can check behind me. Also, let me know if this is the right place to post this on the website Thank you.
