This Mod will change your Cargo Bob helicopter into a Big Bob Vehicle Transporter. It is something I made mostly just for me to play with seeing as it will never work quite right but since it still has tons of possibilitys, works just fine as a regular helicopter and is alot more fun to fly around than the old Cargobob was so I thought I'd go ahead and release it.

I've had a similar Chinook mod that was able to carry things (in theory), but whatever I put in it, handled strangely. It just went mad when I took off. It moved up when going down and the same for every possible direction and crashed the heli. But nvm, I'll try this one too.
