I built mine a few years ago and I didn't use the lightest equipment available so it was a little ovwerweight. I removed most of the dihedral and wing incidence.
Specifications:
PeeWee .020
3/4" elevator and ailerons with covering hinges
Standard 9ch JR receiver
2 - Cirrus 26bb servos
110 mAh battery pack
Cox 4.5X2 prop that came with the engine.

It came out to 7.5 oz, but it still flew fine with the PeeWee .020 as you can tell by the poorly trimmed climb out on it's maiden flight.
