Not too sure as my joystick won't work "nice nice" with my new motherboard. Finally had to break down and buy new USB CH stuff, so I havn't been flying.
The center bases are about 5k with some pretty big mountains around them, and the little I've seen of the rest looked hilly with small mountains.
Staying away while I can't fly.... kinda like having that nice cold beer in its frosted mug just sitting there dribbling drips of moisture down the glass and forming a small pool at the base..... and knowing ya CAN'T TOUCH THE DARN THING !!! LOL!
