I am interested in the Mayhem .40 and want to put a saito 65 4 stroke in it and do some hovering. Can some please tell me why all the threads on this .40 size plane are negative?? Please let me know what the deal is with this plane and does anyone know why it is hard to hover. Is their anything good about this size plane? It seems very compareable with the Twist and the Harrier .40 sizes that is in dimetions of course. These planes seem to get good reviews and their all around the same weight and size. Please can someone give me some real facts so I can make a good choice. Thanks
