Im kinda interested in this one. I wonder how rigid the wings gana be. I like the changeable winglets. Wonder if the performance difference will be that noticeable. The elevator looks a little small but I still like the look of it.

I like the high rudder. I want a slope capable ship that won't loose the rudder every other landing.

In some European countries also available as REELY SZD-54 from Conrad Electronic Link or their partner shops.
Choice between PNP or RtF versions.

This thing is heavier then my Phoenix Evolution.... which i thought was pretty heavy but it does glide better then i thought it would for its weight. This should have a nice glide with its wingspan.........i would hope.

For the glide angle weight (wing load) have no influence. A heavy plane can have the same or better glide angle. The glide angle depends only on aerodynamics, profile and drag.
But the weight increase the minimum flying speed and the sink rate which is also reduced thermal performance.

The wing loading is less than the eflight Mystique, and that flies very, very well.

From the video, I expect this to be a fun flyer that will thermal...not a world beating thermal duration ship made of gossamer. The radian flies well, but it is not "sporty".... This looks be be a higher speed frame than the radian.

The Mystique fly very well but the reason is because the wing load of the Mystique is much much much better.
Mystique: 33g/sqdm (66.7sqdm, 2,2kg)
This plane: 44g/sqdm (25.8sqdm, 1,15kg)

And the difference is also bigger than it looks because you can't compare "wing load" between planes in different sizes because a smaller plane need a lower wing load for the same performance.

You can use the Wing Cube Load (WCL) if you will compare planes over different sizes.


The Mystique have a WCL of 4
This plane have a WCL of 8.8
The difference is like night and day.

The Conscendo was the best "sporty" and floaty plane on the market and it's hard to impossible to find a RTF foam plane with similar or better performance.
It have more wing area than this plane but only the half weight.
