Near disaster for a ducted fan RC jet on its maiden flight

When the CG is too far forward, requiring a lot of up elevator just to fly level, landing a ducted-fan RC model plane can become very difficult, as this video demonstrates.

This was the first flight of this airframe with a new OS91 engine.

I threw in the "interesting arrival" of an ASP61-powered Bobcat 52 as well, just for your entertainment.

I HATE those NItro DF.. they have no reason to exist,,, really .. just crash it or make it electric..

[mythicalhell]

@MSargeNZ why?

[geekfish]

So much airspeed on landing..... Won't stall with all that wait in the front, but good luck landing...:)'

His wings are too close to the ground and getting ground effect.

@SPAINFALCON sabes que yo no se cual avion empezar pero yo te reccomiendo que si apenitas estas empezando a volar, uno electrico porque quizas no podras con el de gasolina... puede que se vaya fuera de control. y si lo chocas, no es tanto el precio que perdistes. soy bilingue

[SPAINFALCON]

Buenas! Hay alguien que hable español? Quiero iniciarme en este mundillo y no se con que avión empezar. Un entrenador de gasolina, o mejor uno eléctrico mas barato. Alguno sabe de algun canal de habla hispana para comentar? Gracias a todos y disculpar las molestias! Un saludo

@MSargeNZ Nitro engines is all they used back in the day for ducted fans. But then again I been flying since the 80's so this looks normal to me lol. Well now days turbines and electrics have become more popular.

Good to see Nitro powering a fan unit. Dont see many any more. Great video!

@mythicalhell Oh I see. Well, I don't really know yet as I'm just getting into RC(newb still)and trying to learn as much as possible.

peace and happy holidays

look at vid at 17 sec mark..nose is up far enough to land properly. smoother hands and some expo and all would have been well.

[MSargeNZ]

@thebobzilla He may have the CG to far foward, and thus not have enough elevator to increase the angle of attack to a point at which the model will not bounce. Compare it to trying to 'fly' a model onto the deck by just pointing it at the ground. A bounce is almost guaranteed.

[MSargeNZ]

@mythicalhell Well it's just my opinion, but nitro engines screaming at stupidly high rpm don't do it for me. Electric ducted fan on the other hand I really like.
