Now there's some color contrast! Definitely not the fastest delta, quite possibly the slowest. Definitely a great flier.

Of course I vote for the Screamin' Demon - I expect a high speed ride and a rush of adrenaline and get it every time. The tracking, smoothness, high/low speed ratio are all exemplary, and flies real nice A/E aerobatics when not rushing around at top speed, although it can do them at top speed too if the pilot is up to it. Dunno how the roll rate compares, the best I've managed is about 12 a second while climbing vertically, but I could dial in some more throw if it needs it.
