Fenestron

A Fenestron (or fantail, sometimes called "fan-in-fin") is a shrouded tail rotor of a helicopter that is essentially a ducted fan. The housing is integral with the tail skin and like the conventional tail rotor it replaces, it is intended to counteract the torque of the main rotor.

Interesting picture - Mi-24A with the fenestron:

Autorotation

Using autorotation helicopter can be landed safely in the event of complete engine failure. Consequently all single-engine helicopters must demonstrate this capability in order to obtain a type certificate.

The height–velocity diagram (for a specific helicopter) shows the flight profiles, where autorotation can be safely performed.

Articles on Wikipedia about autorotation and H/V diagram:

 

If main engine or both engine fail, but helicopter was operated in the safe H/V profile, then it is possible to land safely. It is a safety feature of hely, so don't be afraid to fly! ;)

Another scale model of Ekranoplan Lun

Anigrand 1/144 Ekranoplan Lun by (sky_devil)

This model is better then the one from the previous post, but it is still missing some parts, which I would like to see:

• copper protection on one of the engines
• the ailerons on the wings should be down

Kamov Ka-26 rotorhead looks very complicated. Would be nice to find a model of it to see how it works...

Oculus Rift is an ideal match for FPV with pan-tilt camera!

rc-fever is not publishing bad reviews?

Some time ago I bought Upper Blade Motor replacement for my UDU U806. The motor I received doesn't really match one in the heli. I wrote a review:

It was send for approval to webmaster:

But it has never been published!

UPD: my feedback was finally published but it took a long time...

Walkera Mini CP vs Blade mCP X

It looks like "Walkera Mini CP" is a little bit better then "Blade mCP X"...

Helifanatics

http://www.helifanatics.com/ - "We are helifanatics and our favorite type of RC helicopter is a RC scale fuselage helicopter because it looks like real helicopter and they flies like real helicopter. We love flying them, we love owning them, we love collecting them and we especially love the sexy technology that goes into making them fly."

Agree! I also have the same passion! But another big thing is FPV. I think FPV can give you the feeling, that you are flying!
