I make and fly Thomas' Jyro.
This contra-rotating gyrocopter flies very well.
I say I was the first to make it in Japan and skip it.
That's why I drew the Hinomaru on the aircraft.

The WIG machine "Red Dragonfly" that was once operated by TEST in Hiroshima was reproduced with a radio control. The actual boat runs slightly above the water surface due to the ground effect created between the water surface and the wings of the WIG machine. It uses an outboard motor, which is rare for a WIG machine, and is compact and lightweight. Manufactured by M Shipbuilding in Japan. Although there is a speed difference, the actual boat runs I was able to reproduce it.

RC model of YAMAHA's experimental hydrofoil OU32 manufactured in 2008.
At the time of production, it was only possible to sail in a straight line, but in 2020 this year, the hydrofoil system was completely refurbished to enable free turning movement as it surfaced. Its appearance is like a fighter running on the surface of the water.

New Kawasaki JETFOIL [YUI]
RC Jet foil YUI (5 min 6 sec)

This is the first model of a new jet foil ship that has been in service for the first time in 25 years. ‥
 Although this model is completely original and has high maneuverability, it is the world's widest model, but it is the only jet-foil radio controlled model ship that I can only make.

Launched and launched my own 3307.
Damen3307 RC Model Ship (4 min 50 sec)

The acceleration was more than expected.
The new AX hull has excellent performance.
What made the AX-BOW into an RC model ship
I am the first! ..
Even if you model the hull of low resistance with excellent straightness and acceleration
I confirmed that it has the same effect.
It was also found that this boat did not induce the triangular towing characteristic of the drainage type. A small, low towing wave is generated, but it sticks to the starboard and flows so as to join the wake of the boat without developing.
However, turning performance has some quirks.
At the beginning of the turn, understeer occurs and when the turn begins, oversteer occurs.
I think this is the same effect on an actual ship.

Tokai Kisen produced and launched a radio-controlled model of the “Ai” jet ship operating between Tokyo Takeshiba and Izu 7 Islands.
The hull design is the late Uncle Tris, Ryohei Yanagihara.
I have produced three of his design works, “Rainbow”, “Friend” and “Daisen”. In all cases, the paint masking work was difficult due to the unusual pattern design. This “love” also has a heart-shaped design,
The curve masking took time to reproduce. Even so, the pink color of this hull is the first color in my ship's coloring and I feel a culture shock.
