EXI 450

So i am going to build an EXI 450 and i know that you have to buy the electronics seperate. But i can not find a complete list of exactly everything you need to build it. Does anyone know everything that you need and the number of those items to build the heli?

1 - Brushless Motor
2 - Brushless Speed Controller (30A and above)
3 - (4) Micro Servos, 8 or 9gram
4 - Head Holding Gyro
5 - Transmitter and Receiver

just so you know, hobbypartz is selling the sg90 towerpro servos for 3 bucks something, get atleast five so incase one of your servo goes bad, you'll have extra to replace it. Personally i used the 30 amp volcanoe series but i am upgrading all my 450 helis to 40 amp esc,. like nuttcaze said, you needa brushless motor, alpha400 3500 kv, this comes with a pinion and i believe its 17 bucks, and get the telebee gyro at helidirect, then your good to go. once you have all this, you can check Nuttcaze's video on how to build exi 450 as your guide. It would be wise if you have a dx6i or dx7 transmitter. It's a lot easier to pragram your heli that way. good luck !!!
