I sailed my DragonForce 65 with Catsails A and short keel in medium wind conditions yesterday.

The first vid shows my DF with Catsails A and the stock long keel.
The sails keep good shape. The visibility is also good under the sun.

The second vid shows my DF with Catsails A and the optional short keel.

Today I flew my XK K110 with Futaba T10J in moderate wind conditions; around 2 to 4 m/s wind.
The heli is so stable, not so twitchy even in 3D mode, the tail holds so well and back-flips are easy.

The flight characteristics are similar to Walkera V120D02S or Blade 130X.

Great little heli!

Today I sailed my Steerix Fusion Catamaran (AKA Joysway Binary Catamaran) in light wind conditions on Saiko.

Although she run so well, she was capsized suddenly. It took about one hour to retrieve her drifting ashore to the opposite bank.

An almost still pond showing ProBoat Ragazza in its water.

Lean your head 90 degrees to left side and watch the vid. You will find a bird or a flying wing gliding

Today I sailed my Ragazza in light wind conditions on Saiko.

It is a lot of fun to watch my Ragazza leaving her wake behind.

Last Wednesday, I sailed my Ragazza 39" in medium wind conditions on Saiko.

Although some fine-tuning might be required, my Ragazza run pretty well.

I took several short vids by myself.

Settings:
The end of the main boom is about 1.2"(30mm) away from the center line of the hull in the close hauled position.
The travel total is about 2.4"(60mm).

The end of the jib boom is about 2"(50mm) away from the center line of the hull in the close hauled position.
The travel total is about 4"(100mm).

Since it was a bit too windy in this morning, around 11 to 16 mph (5 to 7 m/s) wind, I tried to sail my RC Laser with C sail.

Today I maidened my ProBoat Ragazza 1 meter (39") on Saiko (Lake Sai).

I replaced the stock receiver with JR RG712BX.

I do love the way she sails in light wind conditions. She cruises so gracefully and majestically.
If you wish to enjoy relaxed sailing just for fun, the sailboat is for you. The larger is better, especially in light wind conditions.

Settings:
The end of the main boom is about 1.2"(30mm) away from the center line of the hull in the close hauled position.
The travel total is about 2.4"(60mm).

The end of the jib boom is about 2"(50mm) away from the center line of the hull in the close hauled position.

Last Tuesday, I sailed my modified Westward 18 in light to medium wind conditions on Saiko (Lake Sai).

Modifications:
-The stock boom vang was replaced with an adjustable one with ball link.
-1.5x3mm carbon stick was attached to the upper side of the booms.
-Small lead counter weight was attached to the jib boom for ease of wing-on-wing.

I replaced the stock 75MHz AM radio and servos with the following:

JR RG612BX DMSS receiver with telemetry
JR XG6 transmitter
Spektrum S100 servo for sail
Futaba S3010 servo for rudder

Now the voltage of the receiver battery is shown on the TX (see the pic attached).

Since usually I sail continuously for 20 to 60 minutes, the telemetry is very very convenient.

Today I sailed my Paradise with the new electronics in light wind conditions on Saiko.
I took a short vid by myself.

Tips:
The stock servo, AquaCraft SX-100, might be rebranded Fuataba S3003. You may install any standard servo to the tray without modification.

Yesterday, I sailed my modified AquaCraft Paradise sailboat on Saiko (Lake Sai).

I enlarged the stock rudder with 0.4mm carbon sheet. Then I replaced the stock bulb (12.7oz/360g) with the bulb for RG65 class (21.2oz/600g) from MX Components (see pics attached).

Now my Paradise runs so well in medium wind conditions, approx. 7 to 11 mph (3 to 5 m/s) wind .

I took several short vids by myself.

Tips:
To keep out water, lightly grease the rudder post and apply tape over the hatches and hull.

Today I maidened my new EFX Racer Yellow.

The airplane is very very stable even at low speed. No bad tip stall tendencies at all.

Today I flew my Durafly Me-163 Komet under windy conditions.

Since almost all flying wings are unstable just after launching, the hand-launch is a bit too difficult in general.
With the OrangeRX 3-Axis Flight Stabilizer, my Komet climbs straight after launching though.

May 3, I flew my Poky 40 DS at Sasayama, Chichibu, Japan.

This was the third flight of my Poky. Since the wind was so good, I enjoyed cruising flight for around fifteen minutes. Then I also tried light DS. Sooo challenging!

The landing area is so restricted, we lay a net and land into it.

My friend Takaya took a short vid:
