That's actually a question that can't be answered honestly. It might fly exactly like my real model (which I don't have), but then you could buy one and it would be completely off. It all depends on setup. If you set your real world model up identically to the RF model, you should get results that are rather close to a match between the two. Just remember,RF calculates things as a best case scenario.
Honestly?
It can be answered honestly if he set his plane up with all of the recommended components and the person answering it did the same
I was surprised that the stock setup in RF had a 2100mah pack and the wing loading was listed lower than the range listed in the real planes manual.
