Can anyone tell me if this radio has end point adjustments for steering and throttle, and also if it has a built in fail safe of some sorts?

No, it just has steering and throttle trim adjustments. Not 100% sure about a failsafe, but I believe the current version (v.3 I believe) does have one built into the receiver. I you want EPAs on a cheap system, look at the GT-3. It's only minor issues are throttle/steering curves set improperly from the factory (easy fix in the menu) and sometimes the steering return spring will break its pin (simple 5-minute fix). I have it and it has lots of great high-end features at a good price.

It does have a fail safe but its not mentioned in the manual. And yeah, just like G33Kster said, if you want those epa and other features, have a look at the FS-GT3. I just got my GT3B yesterday and I believe it has the same features as the GT3.
