From time to time I have a problem starting the drone engines using the CSC. I try inner corners and outer corners and they just wont start. I can control the gimbal no problem. My app (either dji-go or Litchi) tells me I have a good connection. I reboot the drone/controller & try again. Sometimes this goes on 2-4 times then, like magic, they start. Very frustrating at times. I never understand what I did (or didnt do) to get it working. Anyway, my question is, is there any other way to start the engine other than csc??
