Currently the Locust 3S has bugs with rocket launchers. Equipping four rocket launcher 20s or 4 rocket launcher 15s(two on each arm) it displays the incorrect model and shows a srm6 instead as the 2nd launcher per arm.
The rocket launcher 10s are correct on the left arm but the 2nd rocket launcher 10 on the right arm will incorrectly clip into the first position. This covers up any other missile model used as well.
Not sure if related or design decision but srm4s have the same model as srm6s.
