Hyper ST Pro Conversion

I have decided that I want to convert a HoBoa Hyper ST Pro as my next RC since my RC18T FT is nearing completion. It's going to take a long time to do this project considering I won't be able to get a job until September. A Bl/LiPo truggy has been my dream RC since I got into the hobby and I'm going to build one. I've done a lot of reading about the Hyper ST Pro and from what I have read it "handles like a buggy" and "is as durable if not more durable than a Savage". That makes it seam like the perfect Truggy for me. The $330 pricetag is also a huge plus.

My list so far:

Hyper ST Pro Kit - $350 w/ shipping
Zippy Flightmax 5S 5000mah 30C - $100
KD36-74-09XL 1900kv - $30
MG996R Metal Gear Digital Torque Servo 210oz - $30
Lutach LT 6S 150A ESC or Castle Creations Mamba Monster Max v3

Does that seam like a good list minus the motor. I'm just thinking about that motor because it's only $30 and would hopefully last long enough for me to save up and get a CC Neu 2200kv.

As for the Motor Mount and Battery Tray I was thinking about making those myself. The motor mount wouldn't be that hard from what I've seen, and the battery tray would be easy if I used some lexan. I just don't want to spend $45 on the motor mount if I could make one that would work for under $10 and same goes for the battery tray.
