To elaborate on my fellow Texan's words of wisdom, you've gotten ahead of yourself just a bit. But first, welcome to the hobby and to RCU!
To answer your questions: The complications you'll run into, aside from the normal beginner difficulties, are that the Hellcat will be hard to keep oriented because of its color and shape, will not self-correct, and will be difficult to land without stalling and crashing. There are planes made to help beginners get over the hump of learning to pilot called trainers. Skipping the trainer step is one of the costliest mistakes a new RC pilot can make, and the cause of many a promising new hobbyist to quit before even learning the basics.

Reading between the lines of your post, you want advice on how to get started in the hobby successfully, right? If that's the case, put aside the Hellcat and buy a trainer. If you absolutely must be self-taught, then the HobbyZone Super Cub is a pretty good first plane. If you can get an instructor, your options open up a lot. Download the FMS simulator and get a cable off Ebay to attach your transmitter. Alternately, you can buy a control box for FMS off Ebay that comes with a free FMS CD. Learn to takeoff and fly constant altitude circuits and do no bounce landings consistently on the Super Cub (harder than it sounds), then give the Hellcat a try.
