The motivation for a flight affects the SPEED of the ships. You can motivate a flight with a start time more than 40 minutes. If the flight is between 40 and 60 minutes, you can motivate it up to 25% and it will be completed 25% faster. If the flight is over 60 minutes, you can motivate it up to 50% and it will be completed 50% faster. The flights of type Recycle CAN'T BE MOTIVATED..All other types of flights can be motivated and completed faster.
If motivated fly has been returned in 5 minutes after you send the fleet, half of the spend nanocredits for the fleet will be restore to the player.The round is to the smaller number, which means that if you spend 5 credits it will restore you 2.
If Alliance А declares a war on Alliance B, the players have right for motivation of a flight on the following conditions: a flight with duration more than 20 minutes can be motivated with 25%. A flight with duration more than 30 minutes can be motivated with 50% (applies both for the players of A and B). If Alliance B is declared Union with Alliance X, than the war declared by Alliance A doesn't affect in any war Alliance X. Nevertheless, if Alliance X declared Union on Alliance B, than the war rules apply both for Alliance B and Alliance X. This means that you should be very careful when deciding to declare a Union - you could end up taking place in very unpleasant war actions.
