I've got one with about 12 or so flights on it and did the following:

Modified tail heavily - just my choice
Glassed wing seam - do this!
Put on carbon gear
REPLACED tail wheel immediately
REPLACE main wheels as they fall apart - foam I would recommend not even installing the stock wheels. Replace immediately if you're on pavement and save your wheel pants from eventually hitting the ground.
Upgrade tail wheel springs - not much control with the factory ones - in my opinion.

I did use the factory tank and actually thought it was great... wish it was bigger but it fit perfectly!

Engine: Brison 2.4
