Good news, I upgraded my Aerobird with the Xtreme tail option and it flies much better now. I was even able to do a loop, it wasn't the prettiest thing but it definately looped. The Xtreme tail upgrade includes a larger v-tail with bigger control surfaces and a 7 cell (8.4V) battery. I like to use the lowest hole on the control horn so I get the most control surface movement.

In winds of 8mph or less it is a real pleasure to fly now.
