Just my 2 cents, but I wouldn't be so quick at cutting off those pylon tanks.

The classic flash flies a little different than the UF but it flies great. And those pylons make it easier to see and carry around.

Also the classic lands a little more 'draggy' more like a conventional jet. The UF is more like a pattern plane.

I love them both, have flown them both. Just my own personal opinion but I would not want to cut the ones off mine. Just saying ...
