[Leo Ho]

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

We tested with different RUDDER SETUP. Found that this setup has pretty good stability to turn at full thottle:

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.

Happy rc boating,
