I made an Rc blimp using a 1/350 Academy Cutty Sark for the gondola. I had to widen the hull to accomidate the electronics, then had to made it light enough to achieve neutral bouyancy.
First up the gondola with excess plastic removed:
side veiw:
front:
Deck:
on helium bag:
total model weight( sans bag) 93 grams
Used very thin clear plastic for much of the body work. Deck is a picture ofwood planking glued to top. Houses and chain wheels are cut from the original kit's deck.
