Joe,
The cheapest system new is the Nitro Planes Falcon 120 and King Tech 80. You can
use all standard servos, except the elevator, which I use a good digital (not high dollar).
There are some mods needed, but not major (glue joints and glassing the formers).
Go fixed gear first, put brakes on mains for AMA (get used set). If you have the radio
system, you can do the complete system at $2000 if Todd at Dreamworks still have
the K 80 for $1550. The plane is a dream to fly and land. The Falcon at Nitro is still
$179.
