Question on Drone Upgrades in Rigger 5

Specifically Armor: Are we paying for the difference in armor, or are we paying for the total end amount of armor? the wording in the Armor section states "Cost equals the

**upgraded** Armor multiplied by the drone’s Body, then multiplied by 200." But the Example shows total amount "Increasing to an Armor of 15 on a Body 3 drone would cost (15 x 3) x 200, or 45 x 200, or 9,000 nuyen." Which is correct?

EX: Upgrading a Roto-Drone to Armor 16 from Armor 8: Am i paying total cost: (4 x 16) x 200 to equal 12,800?

**The above is correct for SRM. rr**or am i paying the upgraded armor cost: [4 x (16 -

] x 200 to equal 6,400?

This is probably a question for the Errata team as well, and as such i will post there.

Also, if you are purchasing upgrades for your drone, specifically in the case of Sensors and Pilot Programs, is this a situation where you pull the old one out and put a new one in? so you can get 20-30% of the value of the part being pulled out by selling it back? or is this more of a case of "expansion" where you add to existing capabilities? which could imply that you are upgrading the armor as in my 2nd example above. Leading back to that example as well, if it is a matter of complete replacement, do we get 20-30% of the value of the armor being sold back if we are doing the "total cost" example?

**For both questions, you pay total cost and do not receive anything back via a selling back scenario. rr**
