RE: suitable esc
If you are referring to the Park 450 Brushless Outrunner Motor, 890Kv, it has a maximum continuous current of 14A and a maximum burst current of 18A. So a 30A or 40A ESC will be fine.
E-flite recommends a 20A ESC for that motor (see: http://www.horizonhobby.com/Products...rodID=EFLM1400), but that is the smallest ESC you should use; a larger one is always OK. The only downside to using a larger than required ESC is that the larger ESC might weigh slightly more than a smaller one. But the larger ESC will run cooler for a given current load, and that's a good thing.
