Will be made of fiberglass/polyester.

Just want to be sure, are these pictures of a plug or an actual boat?

They are plugs.

As boaters suggested. Need a stronger boat bottom. Tested with one with the rear 55% of the bottom and transom made with double fiber layers, equivalent to 600g/m^2. Weight increased by 90g. Feel that the bottom is now very strong. The hull weight is now 850g.
Believe that can make the whole bottom and transom with double fiber layers and can maintain the same shipping cost. Estimated hull weight should be 880g.

Hello boaters,
Since the bottom made with 600g/m^2 fiber. JetChopper30 hull specification changed to:
Weight(new): 850g(1.87lbs)
Bottom and transom shell thickness(new): 2mm
Deck and hatch shell thickness: 1.4mm
Length: 760mm(29.92inches)
Width: 230mm(9.06inches)
Height: 129.5mm(5.1inches)
Deck to keel height: 100.6mm(3.96inches)
Resin: polyester
Fiber: MAT, 300g/m^2 for deck and hatch, 600g/m^2 for bottom and transom
Surface material: gel coat
The bottom and transom are now very strong. Yet, some sort of rails, connecting rods for the motor mount are still highly recommended.
Happy rc boating,
Leo

Refer to Glenn Cupit's article on rudder set up, RUDDER "CASTER", A LITTLE CAR TALK, BACK TO BOATS. Articles talk about rudder length and rudder lift. With many testing, I got the following conclusion on JetChopper30 set up:
Offset the rudder 55mm to the right. Pretty stable turn at full throttle. Rudder too close to the centre line has too much prop., keel lift, lower turn stability. In perfect situation, rudder lift just balance the prop., keel lift.
