Help with Techs

[TerraBoom]

I just started working on TerraTech today, and I wanted to know what is the best cooperation to make a tank/plane??

Hawkeye for Tanks, Better Future for hover vehicles that can fly. Hawkeye also have a lot of plane parts so you can build some good fighter type planes. But their parts will probably have to be made instead of earned doing missions. You can also buy them when you've maxed out the license for them as you get terminals to buy items from if you have the money to. You get the money by harvesting resources and selling them, it's a good idea though to refine them before selling them as they're worth more than raw resources.
