You're learning to fly, not going someplace. How far you can fly is important during cross-country training, and the airplane's range is determined by how much gas it carries divided by the amount of gas the engine burns times the airplane's speed. Most training airplanes carry 2 to 4 hours of gas and fly at around 100 mph. The cost to rent these airplanes per hour is at least equal to their speed, so your training dollar may be better spent on a simpler trainer. You can save the go-fast airplanes as a personal present to yourself after you earn your pilot certificate.
Many trainers have just a few communication and navigation radios and all the essential instruments.
High performance airplanes generally have all the latest radios including GPS satellite navigation, advanced instruments, and autopilots. Learning how to navigate from one airport to another will be part of your training, and you'll put into practice on flights with and without your instructor. You'll first learn pilotage, where you look out the window and compare the landmarks you see on the ground to an aviation sectional chart, and dead reckoning, which is used in conjunction with pilotage. Short for deduced reckoning, dead reckoning is flying a compass heading that has been corrected for such things as the wind for a certain time at a certain speed. There are several forms of radio navigation, and you'll at least learn how to navigate with VORs, very high frequency omnibearing radio ranges.
