Today I flew my Angela in medium wind conditions.

The airplane is very very docile, not so twitchy as a flying wing.
The butterfly/crow is very helpful for the spot landing.

Tips:
Keep speed.
Never fly in weak lift or in poor wind conditions.

My friend Yoshinori and Takaya took a short vid:

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

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.
The travel total is about 4"(100mm).
