RE: How's this for a second plane
Newb,
The Ultra Stick series from Hanger 9 are GREAT Flying planes! They're very versatile, can fly fast, slow, sport, 3D and carry a payload (camera, bomb bay ect) I'm flying the Ultra Stick Lite (1.20) now with a Super Tigre G2300 and it flies 10X better than my Superstar did. i'm really big into 3D and pattern/IMAC and this plane does whatever I want it to. I can fly lazy circles, loops, rolls, hammerheads, and spins on Low rates then flip it to High and pull every manuever in the book! I know the 1.20 sized is way more expensive than what your looking for but Check out the .40 sized.. I thinks it's around $130.. IMO the sticks are some of the best planes flyin.
now with your other plane choices:
I'd say the GP Patriot and Lanier Stinger and Shrike are out for sure. I wouldn't go with the Air core plane either.
The Goldberg Tiger 2 is a great Flyer.. i've flown one with a Vmax .52 then later the guy opted for a GMS .76. It flew great with both but one mod to make is to extend the rudder out 1-1.5 inches. If you can shell out for the .60 sized it's a great performer with a SAITO .91 or Super Tigre G90
I've never personally flown the Sig SE but there's a guy flying one at our club and it seems to fly great.
i've never seen a 4-star fly.. but I've heard they're similar to the Tigers.
I'd go with either the Tiger or the Ultra Stick
