Elipsoid Evo 2.8E (ARF)
66 oz. (1865g)
Hacker A30 12XL, 14x9 folding
MVVS 4.6/840, 14x8 folding
One of the most impressive European made sailplanes that we have ever seen, the Elipsoid Evolution (Evo) flies as good as it looks. Gentle, smooth, and very long flights are the standards for this beauty. The careful use of composites with competition balsa, creates a good light structure that will hold its shape for a long time. The synergy of low weight and strong structure is very unusual in a production sailplane and can only be achieved with careful attention to design and construction. The manufacturer uses the latest construction techniques such as CNC milling and laser cutting. Each part is carefully hand-crafted with meticulous attention to detail. Value is simply incredible.
The Elipsoid Evo is just the right size for perfect thermaling.

Flies like a dream. Penetrates the wind beautifully, turns without dropping much and presents lift Very well. If you are a beginner, ignore my comment about cg below and use the forward most point or even a little forward.
Flying weight on mine was 52 oz making the wing loading around 9.6 oz/sq foot
The page calls for a thin servo in the tail. I purchased one but wound up putting in a standard micro servo. There was then room to mount the servo where you could actually replace it without having too many issues.
The rates published are pretty much right on and it is very to get way beyond the published rates easily on all surfaces. In fact I will be going back downstairs and reducing the mechanical throws.
This things will turn on a dime while pretty level and not loosing too much altitude
The firewall was loose in the front of the fuselage and I had to add some glass to get a tight fit.
There gliderdrive motor I used will take it verticle, and with a 4 cell 2200 and a micro servo in back I didn't have to add any lead in the front. There was an issue with being able to fit the canopy hold down screw head between the fuselage and the motor so I lost maybe 1 degree of down thrust to accommodate this. I miss this down thrust I would have liked to have even a little more. But I like my gliders to climb because I said so not because I turned on the motor. I am thinking about lowering the back wing joiner hole so I can get a little less climb when the motor turns on.
Also I haven't measured yet but I am guessing the Decalage is probably 3 degrees or so.. This will be Very easy to fix as the T tail makes it easy to adjust I Like 0 0
The back side of the CG range will eventually be abandoned and will be moved even further back, but right between the 2 points was a great place to start
Just plan on cutting the plug off of your servo extensions so it can be pulled through the wing because it was just to difficult to pull the plugs t

I am so excited how this plane flew! This is my first glider build so I was nervous but at 75% throttle, the plane practically flew out of my hand and was at a good gliding altitude within seconds. The Neo 780kv motor ran on a 4S 1800mah lipo and a 40A ESC is the perfect match when accompanied by a 14x6 prop. Flight times were nice and long.
I give this 5 out of 5 stars for a flight review for its extremely easy handling. Landings are a bit tricky if you are not used to landing a glider. I recommend programming flaps into your aileron configuration.
I am so glad I purchased this plane, the investment paid off in the first 30 seconds of flight. I recommend this elipsoid evolution to anyone wanting to get into powered gliders.
