Without question, you NEED GOOD servos on that heli. You will need all the help you can get. For this, I HIGHLY suggest the DS-415's for the cyclic and the DS-420 or DS425 for the tail. These small heli's HATE cheap servos with a passion and will drive it's self into the ground to prove it. I know, I had one lmao. And it was nicknamed "Nightmare" for a VERY good reason lmao.
