This is the SeaWings Fighter v1.0 of the Empire from the RA3.We make more upgade and change about this.Actually,it can take-off and landing in any flat surface on this simple planet.With 12 missiles,it is more like an air-defense missile boat and not an aircraft.So it is heavily,firepowerful,and easy to understand.

Operation:
Act4 - Self-explosion(Detach all missiles)
Act5 - Parachute
Act6 - Flight Beacon
Act7 - Guns turret control system online
Act8 - Radar turret control system online
VTOL cotrol - turret aimest up and down
Trim contol - turrest aimest go left or right

Attiation:
1.Don't try to lanuch missile when the target below 30 degrees of aircrafts level(May hit pilots'self).
2.Don't try to lanuch missile when your sailling above 150MPH,or drift on thewater in a high speed,it maybe stuck the missiles into a dangerous situation.
3.Don't try to lanuch Interceptor when your are sailling,this missiles ignition is a little late(May drop into the water before it ignition).
4.Don't touch Act4,we set this so can make the missiles have enough detach force,but also means it can make a self-explosion.
5.Don't try to get guns turret degrees change which situation you cannot understand,some point of view are not able to be shooting.
6.Don't fire the guns when you keep landing on the ground and turret downward.
7.Don't make the missile boxs into water,it can make the missile's ignitions off-line.

Tips:
If you want to let it be a normal fighter,than do well like this:First Act7 is online then De-Act8,push the VTOL up,so can make the guns aimest to the 12 o‘clock.After that we DE-Act7 and make Act8 back online,so it can an ordinary fighter.

So that is all,thank you for your download.
