Thnx for your reply and your advise. I have seen the one and two motor mods with removal of the fake engine. I also found this one. It uses 4 motors with keeping the fake engine, what do you think of this one?

Does somebody have a link to the easy body removal mod? Cant Fins a separate instruction for that.
