C701 wont lock hellicopters

[RPY Variable]

My understanding is that it is an air to surface missile. Nevertheless, it should be able to contras lock a helicopter. The AGM-65 can do it, so this one should do it too. Then it may or may not hit, but at least it should be able to lock.

To lock the AH-64, you have to set the sensor to 15m width, I ran into the same problem, and 5m it can't find it but 15m it can.
