Well Im happy to report another balsa-box success! Works excellent! The carb plate worked pretty good but there was still the occasional loading up while inverted but with the box its completely gone..no loading up at all inverted..in fact you cant tell ANY difference between upright and inverted flight..I tried to get it to load up by doing long inverted elevators and rolling from inverted to upright and it never missed a beat! If anyone is having those issues..the box works!!!
