RE: CoroCub - a little bigger one.
It is going. Unfortunately I can not spend as much time on it as I would like so it is going slowly. The wing is finished in ARF state, so I started to work on the fuselage. The tail section is going by original instruction from SPAD site. The only change I did was mounting servos on the tail (rudder and elevator will get HS-475HB each), and mount the tail wheel bracket. I also prepared hard points on the elevator and the rudder for control horns. Even now, not glued together, the whole tail is stiff and strong. I am surprised that so far the fuselage is very light - as for the size of the plane.
If I will have a camera and someone to operate I will provide a video. I hope it will fly like a very big trainer. I simulated it in RF G2 with all parameters and in G2 it flies just great. And so far RF G2 is very accurate for the flying envelope of models I built. I simulated my H9 Edge, Powerline Hobbies Edge, Giant Wilga and even GWS C-47. So I don't expect any surprises here.
