RE: Top-Flite 1/5th F4U Corsair ARF Group Build and modification thread
Looking very nice MRadu. Regarding the drop tank I made some large ones for a friend's P-47 project that were droppable. We were concerned about them breaking as well so I vacuum formed them from very thin styrene and then glued the two shells around a skeleton made out of 6mm Depron foam. The tanks are very light and thus do not break when dropped. You might have a super detailed static display one from glass and then use a simplified vacuum formed version for dropping. Just a suggestion. Good luck with it either way.
