What is it that makes this plane so snappy? From all the threads I've read about it, it sounds like I'm going to need a change of shorts and a large garbage bag for the maiden.

Also, I got a email back from Sullivan pertaining to the flex tanks:

Randy:

The gentleman who originally designed and specified these tanks is out of the office and will be for two weeks however I did to some research with our plastic resin supplier. It would seem that there should be no problem with compatability of this material blend with gasoline based on the known chemical compatabilies. Keep in mind however what we had spoke about regarding addatives. I am sure that the chemical compatability tables do not take these into account. Based on this I would reccomend testing these yourself, our offer to replace them if they fail still stands. I would note two things, one is the weight the other is the strength at the knit line (centerline of the tank). For the weight just do as accurate of a before and after weighing of the tank as possible. If you do not have a gram scale or something comparable a simple balance scale will work fine since you are just looking to see if there is a change not what it actually weighs. Please keep us posted.

Sincerely,

So I guess I will take his advice. I'm going to fill it up tonight with a 50:1 mix, let it sit a week or so, and re weigh it, and check the seams for strength.
