I've been working on this with the ultralight. If i notice an organization is dropping cargo on their hangar, i try to ninja in on my glider. If i see they are driving a vehicle back i prox mine the road in and swoop down after the explosion and straight into my hangar. Granted this is a bit of a risky proposition due to the amount of armed aircraft that will notice you as soon as they get an unintentional lock on.How about just playing as a cargo-bandit?
Even with double money added it wasn't worth doing the missions as they're all so tedious.
Wouldn't make you popular lol, but you would skip the missions.
There is much to consider when trying to use the glider in combat. Also, it only takes one mkii explosion to take out the fragile craft. The payoff is almost nill but the satisfaction is quite near the pinnacle of what gta allows.
Edit- on topic, some times the anticipation is the most exciting part. The vehicles are mostly fun and add a balance to the game that wasn't there when all we had was the lazer. Now, the medium sized (the most deadly) aircraft are easily downed by the mkii HS explosive, whereas the small craft (moderately deadly) are a much harder target for ground snipers. This update adds the most balance to the game to date.
So, while the missions are meh... the juice is worth the squeeze. Lastly, the payouts are indeed trash and the update is the most expensive yet. C* moves in mysterious ways. I CBA to grind anymore and i think other veterans of the game are following suite or quit.
