Thanks everybody!
Yes, I know, the bodywork is far from best, but it's the best look I've managed to achieve. I wish I had those flat red panels from the 42029 set.
Unfortunately I don't possess any PF motors. If I had ones, I'd definitely use them.
Yes, I'm aware of this, let's say, feature of the chassis, that's all because I don't have those spherical joints. But in fact this parasite swinging adds a little of extra flexibility, which is nice :)
