I'm getting my e7se purchased on Friday and used but I have a few questions I have a pyro 700 52 setting around and would like to no if it's suitable for this heli. My target headspeed are 1800,1850,1900. If the motor is suitable will the stock pinion work or will I have to go down a size. also with those headspeed It's coming with 106 tail blades or should I get 116. Just trying to prepare before I get her thanx
