I built the original (not a high-quality ARF, by the way). Here are the updates on the new one according to Cermark's web site:

New version with some upgrade features:
AVIAT Team color scheme: Blue on white or traditional Red.
Quick and simple I-strut mounting method.
Metal cabane and reinforced top wing bottom sheeting
Allows 4 standard or mini servos for additional positive control and :EZ" service
Reinforced firewall with exchangeable Engine Mount (fit any size/brand of glow or gas Engines)
Tail mounted servo for direct Elevator and Rudder controls(no more mixed control cable or pull-pull system).
Laser cut all air-frames and ribs.

The fact they went to metal cabanes and a reinforced top wing is probably a good thing, as several experienced failures there. Mine held up fine for 2 seasons, but I spent A LOT of time going over its many problem areas before flying it.
