EXI T-450 SE Carbon Edition ARF at Xheli.com

Looking to purchase this heli. Is it really a TRex clone? Can you use TRex parts as spares. My only reservation about buying this is the availability of parts.
I would like to use following components, Will this work???? Need a reccomendation for how many teeth for main motor gear. Any advice will be appreciated!!!
Thanks. Safe landings!!!!!

Sorry, missed this somehow. For the motor get this, its the Alpha Brushless that is recommended for this heli and it includes a pinion. And its only $15 - http://www.xheli.com/18h-ee0080.html. Everything else looks good. I'm not 100% sure about the Carbon edition but I know the Squadron and SE 9not carbon) both can use T-Rex 450 SE parts. They're alot stronger. Especially the main gears.
