i have finally got my p-51. it is a hangar 9 60 size, with a o.s. 91 four stroke. now for the big decision. what in the world do you do with the JUNK RETRACTS. second flight one folds up. that was pretty exciting. about the fourth flight they just decided not to stay locked down on landing. enough is enough. i know someone on this forum will steer me in the right direction. what are my options.
