I built this as a display model. Overall shape and dimensions are good. Vacuform parts are terrible. Cowl halves have huge gaps that will need additional styrene added then filled. Engine parts very bad. Wing tips unusable. Balsa is acceptable (barely). Not sure this could be made light enough for rubber power. I scratch built some parts including wing tips from balsa blocks. Modified aftermarket wooden prop used. Silkspan substituted for kit tissue. Large decals for wings will need to be cut into sections and installed to avoid damage (they're just to big to handle). Scratch built cylinders. Although challenging to make an acceptable model it looks great finished and hanging from the ceiling!
