Once I finish my RC18T FT project I'm going to start this over the summer.

So far my list includes:
HoBoa Hyper ST Pro - $330
Castle Creations MMM v3 - $140
HobbyCity KD36/74 9XL 1900kv - $30 (I know this motor is going to run hot but it's temporary)
Zippy FlightMax 5000mah 5S 30C - $100
Custom Motor Mount - $10
Custom Battery Tray - $10

Good luck mate, but keep in mind, it's Hobao and not Hoboa.........
