Hello Tony,

Herve is in France. Paul is in Australia. They might not know about the NAMBA race classes. I don't know too.

Happy rc boating,


Leo

I've ben communicating with Herve and Paul. Herve made me a beautiful motor mount, and I'm talking with Paul now. I'll have an e-mail for you later today.

very fun to drive it.

I am not yet have a chance to build one for own use.

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.

I am sure people would pay the extra for shipping I know I would to have a stronger hull

[leo_home]

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

Those are good improvements; even so the original hull I received was plenty strong. It's generally acceptable to install a transom doubler to better seat the rear hardware so that's not a problem. Using 3/32" plywood for the motor bed is also the simple solution to insure rigidity; also a simple operation. Mine's just about ready to compete in the P-Ltd Mono class at the NAMBA Nationals in two weeks. Should be a promising entry

Cool... watching.

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

looking to get one in red let me know if i can get one soon

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.

I'll check. But do give Doby a shout........

Hello all,

It is available.

I used to have some rudder setup very similar to Tony's. I found that too much rudder lift. Than started a very time consuming testing: RUDDER LIFT: offset distance, distance from transom, blade length/area. Last for more than half a year. Nearly finish. Will soon publish a general text, pretty good rudder setup, aimed for oval racing.

Best regards,


Leo

[Heath M]

any updates on this hull?

Recently rigged a JetChopper30 electric. Offset motor and offset drive shaft. The balancing weight is related to the speed. Would have some new video and figures posted here one some weeks later.
