Since I can't find an actual assembly thread on the Seagull Extra 300 - 75, I'll just start one. What I can find is old.

Mine arrived yesterday from Horizon Hobby, very fast shipping. I'm very impressed with the Seagull Extra 300 - 75. Looks very good, I'm not sure why they call it a .75 though, looks like a .60 to me.

This is the equipment I intend to use.

Futaba 7C 2.4 w/617 reciever.
Futaba 3004 servos on the ailerons and elevator.
Futaba 3003 servo on the throttle.
Dymond D5000 High Torque Metal gear on the rudder.
6v NiMH 2200mah battery.

Tower .75 w/Bisson pits muffler. (because I already have it.)

Radio gear will all be new.

Most of the hardware that comes with the plane looks ok but I will upgrade some of it. The fueltank, landing gear, control horns, and hinges. I may replace some other parts as I get into the assembly.
I will use Robart hinges and control horns. A Dubro Super Strength landing gear because it looks better and I have yet to bend or break one.
