FlyFly MD11 fiberglass ARF

I stumbled upon this:

http://www.hobby88.com/shop/product_...roducts_id=784

then saw the video:

MD11 NEW (2 min 5 sec)


Anybody build one? Does this thing even fly? Two 70mm EDF fans with an expected weight of 5.5kg. Not convinced that's enough power. It seems like there could be a third fan installed in the tail like the real one.

I haven't seen this until now. I know Fly Fly has moved away from foam and into composite. Interesting. I don't have all the details, just making a guess based on what I see from the video - thinking it's gonna be challenging to keep this size of an airliner light enough to be "in the zone", being composite and all. But I am prepared to hope for the best! I think 70mm fans can be very powerful, that's not a problem as long as the motors and batteries are up tot he task, but the weight will have to be watched. It looks scale. I applaud them for trying to get the landing gear, wing and details close! Looks pretty good from a visual stand point.

Good looking Bird, a tad pricey but Very well made.

Did you Guys see Dan Asher of Gemini Jets in that Video?

I did!

That Video was taken right outside Beijing

It's seems very under powered for it's size, plus airliners need flaps to get lift under there wings to fly. I also see lack of elevator throws, it need more pitch. 3rd EDF will definitely help in this case or twin 90mm will be needed in #1 and #3 nacelles. Profile out line of the fuselage looks pretty scale. yeah vertical stab wobbles quite a bit.

I agree Sam, More power is needed, But this MD-11 looks no bigger than 72" inches or so, It might be too small for 90mm Units.

Is it just me, or do the inlets on the wing look too small? Look at the tail fin inlet, it looks bigger.

I think they are generic 70mm Engine cowells off An RC A320 or other RC airliner.

Of course, a single gas turbine in the tail nacelle is the best choice for a MD-11 model. And there are several examples flying with this kind of power.

thats the nobert rouch one they are massive but look the dogs dangles" in the air
anyway"
they have made an error on the c of g (center of gravity) acording to the manual it says the c of g on the md11 is 240mm from the leading edge of the wing" 240mm sits way behind the uc" under carrage) the photo shows the c of g at about 140mm that is just behind the door" but i am abit confused i believe they have made an error any sugestions??

Compare with the instructions on Norbert Rauch's site.
The CoG ("Schwerpunkt") is located 27cm in front of the trailing edge of this much bigger wing. But you get an impression of the correct location.
BTW a tail-mounted turbine needs a lot of incidence to avoid a strong nose-down tendency.
