I dont have personal experience with it but it is definatly a 3D plane and it looks similar to the harrier. as for the engine mounted inverted no worries some are a little more tempermental than others but all should run just fine. I run 2 engines inverted on my planes. A ys 1.10 in my Funtana 90 amd a YS 1.40 in my Quique Yak. Ideal for lateral balanceing.
