RE: balsa 3d
The E-flight Cap 262BP is a worth considering. With the recommended 450 motor and ESC, four Futaba 3114 servoes and a 900 mil Inpulse three cell pack, mine weighs 15.3 ounces. It flys slow flight as good a most foamies, but because of it relatively thick airfoil it flys fast flight or windy flight like a real airplane, with none of the jumpiness of a foamy. It assembled in almost exactly the four hours stated on the box. It is a joy to hover, hovering almost as well as my Reflecton Foamy. Makes air catchs real easy. I've banged it into the ground several times from a hover on windy days and so far it has sustained no real damage. It does great walls, elevators, waterfalls, and harriers, fair blenders and has very little coupling in knife edge flight. I highly recommend it for a light weight balsa 3D plane.
