why do you think the servos are responsible for the "almost" crash? either they work or they don't (fail). i flew for years with 3001 which have the same torque and speed than the 3003. i know of guys which fly with 148 in their raptors. i do not recommend it though.
i use JR servos and have a really strong one for pitch (110oz) and decent ones at the rest of the swashplate (90oz)
