Upgrades are used to improve your plane. The current upgrades have been available since SR2.5, after having been absent during SR2.4.
Most upgrades come with a minor penalty to offset the bonus. Penalties originally included decreased cargo hold size, but cargo penalties were disabled shortly after implementation due to a bug.[1]

phil brand (TM) Useless Upgrades[]
Whenever phil hit a milestone number of posts on the Forum, (post number 500, 800, 2000 or whatever) he began awarding a useless plane upgrade to whomever started that thread.
The first such upgrade, a Grimby Card in Your Props (the text on the upgrade reads "Levernius Fuseli rookie card, it scares pirates and third graders!"), was awarded to Fenriq in November 2007 for starting the thread in which phil made his 500th post.[2]
Awarded to Luca Shoal
Luca Shoal was awarded Monster Truck Landing Gear in February 2008 for grabbing phil's 800th post. It occupies a Wing upgrade slot and increases Acceleration by 1. [3]
Awarded to Maya
In December 2012, Calvin (a Moderator at the time) revived the tradition by having the Devs award Maya with just such an upgrade when he made his 3000th post in her thread. The Spare Paddle has no in-game effect and occupies a single Combat upgrade slot.[4]
