First Big Bird
The Midwest AT-6 is a good first choice
You cuould probable find a kit and the retracts for around $400 or less.
They build easy and fly nice
I have mine set up with a Quadra 40 and standard BB sevos
very econamical
It has a 83" wing to get you in the IMAC class and allways get peoples eye(everybody likes a T-6)
Food for thought
