Also, the mass/power ratio of that B-29 seems very good just seeing the way it accelerates and takes off ! The 4 props seem to deliver a lot of power.
I'm pretty sure that, provided a flat concrete runway, the model could takeoff with only 2 engines running, though it would be difficult to avoid stalling.
Another thing, do they have any instruments on their radio controllers ? I noticed they were 2 "pilots", maybe 1 for the engines management ? I guess it would be possible to put something like an artificial horizon in such a big plane, and to transmit the data to the controller ?
Here's another large model. A 70% size 3D plane...
At some point, I'm wondering if we should call these things models or drones :hmm:
The biggest ouch in RC plane history...
In the first seconds after takeoff, you can feel that something is wrong with the flight model / roll control. The plane rolls constantly on the Z axis. After the turn, it accelerates to high speeds, where it gets uncontrollable... Well, it's the way I see it.
BTW, there is a serious safety concern when you put in the air such big and fast things, could probably have destroyed a small house !
