what you can see here is a set of rc cars wich are specially made to be droped from helicopters. they have (almost) no wheight (about 1 lb each), also they are easy to Control.

controls:
(requires the activationgroup of the car you wanna use)
Pitch: drive Forwards/backwards
Roll: turn sideways
(only for car 3: Trim: Pitch)
note: when you release the pitch, the cars will stop moving.

ActivationGroups:
1,3,5: release+activate the car
2,4,6:activate the self-destruction for the car (2 destroys 1, 4 destroys 3, 6 destroys 5)

about the cars:

car #1 is intended for offroad and Research stuff.
car #3 is usefull for exploring other planes/cars/boats in multiplayer.use pitch if you Need to climb
car #5 has a huge ammount of explosives, wich are spreaded when launched... good luck with that. also, its a good climber. if anyone cares, its the "Seeker Mine" from the game "The Division"
