How to use C4 on drone?

[Ka'shurio]

I just unlocked the drone recently, and am learning how to use explosives on the drone.

I learned that you can place anti-personnel mines on it, and fly it under the enemy's toes to let it blow up.

However, what about C4 charges? Do we just ram it into the enemy, or do we have to press some button?

Thanks!

use anti personel or have a buddy put c4. If you wanna c4 yourself, you have to be really quick with switching back out of the drone and pressing your c4 clicker..
