The most effective way i found to destroy a VTOL or a Condor VTOL is with a sniper.

What do u mean by a sniper? how do i use it?

A: everyone can see that orange thingy in the VTOL ( the rotors )

The most effective way to destroy it is by getting a sniper and shooting these rotors.

The condor is easier and you can destroy the rotor with one shot.

The VTOL will take 2 shots to destroy a rotor but without this rotor it will go down or blow up in mid air.

The easiest and most known way to take down anything.

it gets easier when you upgrade your rpg and turn lock-on on military vehicles.

Just get your rpg out aim at the vehicle and when the aim turns red you fire and you destroyed it ( tanks take more rockets)

If your poor and cant buy the lock-on upgrade you will need to know the physics of the rpg so you can hit the aircraft ( or vehicle )

1: The condor has 3 rotors shooting both in the front will cause it to lose control and explode after 2 seconds. If you shoot one in the front and the back one it will instantly explode.

2: You can blow up a stag tank with 2 grenades ( future soldier DLC grenade launcher)

3: You must take down a Condor VTOL first than a VTOL because the condor carry STAG Commandos (Orange Outfit) they are a real pain in the ass to kill.

4: You can also blow up VTOL wings if you shoot them.

Sorry about my grammar in this guide.
