I thought people were reporting some bad tendancies on the astro hog, or am I mistaken? (easy tip stalls on slow banked turns).

If it's your first low wing I would highly suggest the 4* series. I haven't flown one, but just from reading a lot about them and seeing them fly they are usually the "go-to" plane for a first low wing for most people as a kit.

The US will likely groove and fly faster/more aerobatic, but I'm not sure if most would recommend it for a first low wing. Tough to say, but if you're a good pilot and have quick correct reactions and fly at 1/2 throttle for the first while you should be okay.

GL with the build!
