New Product
Elektro Rookie from Graupner

Finally an Elektro Rookie kit arrived today. I had already mentioned the model in the EasyStar thread as a serious competitor:

While the new Elektro-UHU with 1200mm wingspan already outperformed the EasyStar, its nose may have been its weakness for beginners.

Everything is different now with the new Elektro-Rookie S(olidpor). It is bigger and it comes with many interesting features at a competitive price:

Why do they supply 2 different size props? One is 6" x 3" and the other is 6.3" x 3".

It is all mentioned in the instruction manual :

The 6.3x3" SF prop is for 2s, the Cam Slim 6x3" is for 3s.

Maiden flight and more pictures ...

You really can get this model airborne within 2 hours, but I took a bit longer as I was not in a hurry.

This model is even easier to fly than the famous EasyStar. Straight from the "build board", i.e. living room table, no trim changes were required during the maiden flight. CG at 80mm from the leading edge worked fine.

The model has no tendency at all to spiral dive - even with continuous full rudder and full elevator applied. It is also very tough. I intentionally stalled the model approx. 10ft above the ground and kept full-up elevator. The model took the nose down to pick up speed and hit the ground at an angle of approx. 30° - no damage.

Unfortunately the recommended 2s/2500mAh battery was not available right now, so I had to use the 2s/1500mAh from the Elektro-UHU plus 60g of ballast.

All up weight at the maiden flight was 530.1g, plus 89g battery, plus 60g ballast. I guess the model will weigh approx. 700g with the decor added.

Great model for beginners!

Pretty cool. It least Graupner made it look a little different from the Easystar, unlike the Sky Surfer which is basically an exact clone. I like how it comes with a brushless motoe and CF spars. I'm not sure whether that justifies the $25 (US)price higher than the Easystar kit price. I guess it depends on which brushless motor you upgrade the EZ with.

Having the high T tail makes things a little trickier for connecting a servo to the elevator, but it puts the elevator right in the prop wash, which is good for control at lower speeds.

I'm not sure if I like the internal servos or not. They are nice you have inside where you can't see them, but they take up a bit of space inside which a lot of people use for other things. They also look a little tricky to install. Other than that it looks good. I like the shape of the nose and canopy.

I'd love to see some video...

Well, I would not mount an HD Hero at the wing tip (as shown on their website), but I am sure the Elektro-Rookie can carry about the same loads as an EasyStar.
