Well, as you can see from Pete's pictures, the plane goes together quite easily. Even if you don't have any room to build, like me.
Pic #1 is a picture of my first stock kit Strikemaster (1973-74), just to jog your memory of what the completed .40 size plane looked like. Enya .45 and GeeBee plastic floats.
Pic #2 shows the flap and aileron servo hatch positions. The stock plane uses torque rods but on a plane this size, we think you really should have a servo on each aileron (and/or flap if you have them). Besides, servos are cheap.
Pic #3 shows the super complicated drill bit I made to drill the servo lead holes in the foam wing. You could always trench the leads holes on the surface of the foam but I like to be different. I'll say this though, it takes a lot longer to do it my way. The drill bit is 1/2", using zagi tape to attach it to a 1/2" dowel about 24" in overall length. It is a hand drill and it helps if you have a third hand to ensure that you are going into the wing at 90/90 angles. The Estes BT5 rocket tubes are a perfect fit.
Pic #4 shows the servo pockets and the rocket tube installed.
