From: "Thruster87" If you are worried about paint burning and giving off toxic fumes I think by the time it can do you harm you are in real trouble already so just make it look nice and paint it.Even galvanized steel will rust [ saw a Skyfox Gazelle with a half rusted firewall that was around 15yrs old] .A galv. etch primer then a K2 top coat comes up looking good.

Take any Cessna, fill both tanks to the rim, and go fly. Slightly left wing heavy, just a tad. Switch to the right tank for about an hour, and see what happens. Then, run on the left tank until it's almost dry. Interesting.

Dont shoot the messenger, Ask any aeronautical Engineer, this plane is light wing load, thus, with weight shifted about it will tend to fly in that direction.

I am glad to hear someone from the Zenith/Zenair community actually suggest there is a need to do something about all the accidents. Reduction of gross weight and airspeed limits certainly should help with the future safety record of this design. I am now more hopeful I will receive "Official" design changes for the XL that I decided to wait for before entering flight testing. The ones I want are aileron mass balance and control system force changes as demanded by the NTSB.
