I just up graded from my Avistar to the Dragon 40 by 456 MB.
There is a artical written about it here on R/C univ.

The plane flys great not as fast as the Avistar with a 46 on it but more advanced in flight.
It may be the perfect 2nd plane.

I purchased mine at R/C Country in Sacramento for $140.00 and put my electronics out of my Aviastar in it.

Just a thought.
