S-31 Kestrel

The kestrel was a solid medium VTOL fighter, which could tilt up and down using R and T respectively, and swap between VTOL and normal flight mode using F.

Its prerequisite buildings were simply a service pad, and 3 extractors, meaning it was a very good early weapon for those who had it unlocked.

Sadly, it has been removed from the game, but was briefly accidentally re-added at around 2:00PM GMT, on Monday, November the twenty-third. Rest in peace, kestrel. You will be missed.

Advantages

 * Very good fighter
 * VTOL that behaved like a helicopter
 * Very fast firerate.

Disadvantages

 * High cost and low hull
 * High unlock level
 * Would constantly get stuck in the ground.

You would have tried to...

 * Be smarter and quicker than enemy aircraft, such as a conard, or an enemy Kestrel.
 * Avoid built up bases as it wouldn't last long against AA guns and Sam's
 * Avoid using vtol unless your traveling short distances or taking off, as it made you a very easy target.
