My best ARF's:

EZ Zero (58" span); the best flying ARF but foam core covering is it's weakest point and it is big$$$$$
GP Ryan ST-M; the best value in a Giant Scale ARF I have ever seen.
Kyosho PT-17 Stearman; a very nice surprise for a balsa/ply ARF, a bit pricey but worth it
Sig Somethin' Extra; THE MOST excellent fun to value ratio you can find, I couldn't build the kit version for the ARF price

My worst ARF's:

Lion Models Diabolo; a cheap ripoff of EZ
Thunder Tiger trainer 60; crappy 'shelf paper' covering is the WORST


Jury still out on these 'cause I haven't started them yet:

Kyosho GeeBee Z
KMP Super Chipmunk
Jet Models' Katana (same as GSP's)
