just skim the windmills, get tht first rudder level ASAP, then buy the crane boost and windmill bonus... should b np... go for low leveled out flight, not height.
tip for keeping your sanity.... with all fuel levels starting with the 400k+ ones, just buy an auto collector, and ALWAYS keep enough money to buy fuel once.... just do it, took many many grinds to get tht starting money, and learn tht.

i found wht i assume to be a glitch.... the first play of each mission is the only one tht gives unit experience, however, if u hit restart, instead of continue, after u win the mission, u can repeat till your units r maxed on exp... still love the game, but seemed like an unintended advantage
